Long overdue update

It has been a long time since I have written about the editor. I took a break for a while, not because I wanted to but due to circumstances at work that drained my desire to program. That has been resolved and I have been working steadily on the editor again.

I have designed a new content browser that looks eerily similar to Unreal's UDK content browser. Here it is with some sample content shown:


It does support the same real-time preview when you hover over each item. This helps a lot to identify the correct item before you place it. You can simply drag and drop from here into the scene.

The sample content that is visible in the shot is actually from an awesome game made with Ogre called TorchLight. I am simply using their assets for testing purposes since they look really good and are already in Ogre format. I wanted some real data to play with so I also wrote an importer for their levels which show up pretty well in the editor. I am still missing items such as particles, etc but I have the geometry loading so that I can work on my placement tools first.


I also fleshed out the undo/redo system so that every single operation in the editor (even loading a TorchLight level) is now an undoable operation. I do not want a single thing to happen that cannot be undo. I've implemented a History panel so that I can see the actions that were performed as well as what is about to be undone. The following shows the history stack (grows upwards from the bottom) as well as any actions that have been undone in blue.

I have made a lot of small improvements to the editor such as adding icons to everything, grid snapping, etc. I have also removed every single crash that I have seen to date. I am currently unable to crash the editor and every operation is undoable and redoable which I believe is very important to a good workflow. An editor isn't very good if it crashes on you all the time or if you make a mistake and have to start over.

I've also added a simple form of prefabs as well as the ability to clone an existing object in the scene simply by holding the Alt key and translating the object. This makes placing meshes such as floor tiles extremely easy. I will showcase these 2 features in the next video.

Drag and drop materials

Keeping in line with the 'everything is visual' motivation of the editor, I have added the ability to drag and drop materials from the resource browser onto the 3D scene. The materials themselves offer a live preview in the resource browser while the mouse is over it. As it is dragged into the scene, cursor feedback shows when the material can be dropped and when it cannot. I may add the ability to actually live preview it in the scene as well, applying it to the current object that is under the cursor.

Generalized resource preview

I spent a bit of time and have abstracted the resource browser and the thumbnail creator to support any SceneObject instance. All that is required is that a SceneObjectFactory be created that can return the template names of that particular SceneObject type as well as a function that can generate a SceneObject from a template name. The rest is completely generic.

Here are particle systems working inside of the resource browser. Now that I have the standalone SceneObjects done, I'll have to support things such as materials that have a 3D representation [a plane with the material on it or sphere or whatever] but aren't directly objects themselves. This will be the second phase of the browser which I will get to later.

I love you Ogre/Mogre

After getting home from work, I decided to add a live preview to the resource browser. This essentially lets you see a real-time rendering of the object that is being displayed. For particle systems, it will actually show you the particle systems working in real-time directly in the resource browser. This should allow you to find just the right effect quickly.

I'll be abstracting this into my generalized resource system that I had working in my old editor version so that I can plunk in particle systems to really show it off. Here's a sample video to watch. Pay attention to the knot right at the end. You can see the material rendering in real-time. Also, ignore the box that appears when I hover over objects, that's a work in progress :)

Resource Browser

I've started work on the resource browser which will hopefully make it a lot easier to find and place resources inside of the editor. Eventually, this will feature usability features such as tagging, searching, collections, and sorting but for now, it's pretty basic. There is a button in the editor to trigger the building of the thumbnails but eventually this will either be done by the asset server or by some sort of caching mechanism. For now, this works fine for me. Once you generate the thumbnails, you don't have to do it again, they just load with the editor.

Currently, you can actually drag/drop each of the mesh resources into the viewport to have them appear which is a lot easier than creating an Entity scene object and then changing the mesh reference. This is a lot more visual and fits in with the "You need to be able to build a scene with the mouse" motto that I am going for with this editor.

Custom Object Overlays

I've been working on adding overlays to the editor lately. Here is the design of the actual overlay that I'll be using


This will appear over objects whenever you hover over them. Any type of information will easily be displayed inside of the overlay. This will allow any object to display detailed information about itself to hopefully make it easier to find objects inside of the scene. The overlay can be toggled on and off in case it's getting in the way. It'll follow the mouse cursor around and will be shifted slightly offset as to not get in the way.

The system should be pretty automatic by allowing an OpenGL style Begin/AddTitle/AddBody/End style so the actual layout algorithm should be hidden from the user. I'll be integrating this into the actual editor over the next few days. I've also spent a bit of time scheduling out a task list for myself which should help out with getting stuff done on a regular basis. I've been really busy at home recently so I haven't done much coding in the past few weeks. That'll be changing.

MVC Patterns

I've gone back and finally implemented a model-view-controller system in my editor. I have had plans on doing this for over a year and some now but I finally got around to doing it. Basically, all of my data and algorithms on said data are stored inside of the 'model' while the 'view' of that data in terms of what the editor wants have been broken apart. The collision data for instance is something that belongs in the view since it's an interpretation of the model and only the editor cares about that. The mesh name that an entity is using belongs in the model since it is an integral part of the data. The graphical data associated with that is handled by the view since different 3D engines might represent that 3D model differently.

What this allows me to do is to work with my entire scene without having to load a 3D engine. This will work out great for tools since they can have the typed data that they want without having all of the graphical parts associated with it. We can attach different views as well for different applications.

The other important thing this allows me to do is unit test my business logic separate from my UI interactions. For example, I can now test that my terrain modeling tools provide the proper deformations or material modifications since the graphics engine doesn't need to be loaded. As I've already built up a small testing suite in NUnit, this works out really well. I can make sure that the only parts to break in the future are the UI components. If a bug is reported that is related to the business algorithms, I can fix it, write a unit test for it, and it'll never make it into the build again.

This has broken a few things that require refactoring but it'll be worth it in the end. Unit testing has proven invaluable for finding bugs in other parts that I believed my current changes couldn't possibly affect.

I'm also working on the actual resource management system again for my editor which should be pretty kick ass. I had a primitive version of what I wanted done a long time ago but I want to spend some more time on it again. It should allow for a pretty nice work flow.

Thanks to someone at work for reminding me that there is at least 1 person out there reading this. It's also nice to just have some place to ramble my thoughts off.

Switching Back

I've been in the process of switching back to using .NET and C# to create the editor. The language itself is just much more suited to what I want to accomplish with the editor and I've always believed in using the right tools for the right job. I am now targeting the .NET platform using C# and Mogre which is a managed wrapper around Ogre.

I am also focusing my attention on usability since it will be designers and artists using the editor and not programmers. As much as the property grid is an awesome tool, it is cumbersome, unintuitive, and sometimes hard to navigate for commonly used properties. I much prefer context sensitive menu bars and toolbars. In the following shots, the green tabs are added when a specific object is clicked. This allows for the most commonly used and changed properties to be readily accessible with just a few mouse clicks. Eventually, these will become customizable so that users can drop any properties they want and remove the pre-built ones all together.

Per-Face Selection

So after a single nights worth of work, I now have the ability to select individual faces from objects. I haven't implemented it in anything other than the 'BoxTrigger' but the way that it works now is fairly ideal. Each object itself can determine how it will report faces back during intersections. I just have it printing out which faces were hit but I will build a 'Face Shower Object' thingy tomorrow that will have wireframes around all of the faces. The great thing is, I have factored out a bit of the SelectionManager into the concept of a SelectionSet which holds all the information about the objects/faces/vertices that are currently selected which should be fairly reusable for selection groups if I ever decide to go down that route.

I should have the implementation finished up in the next sitting or two which will hopefully be soon. I am going to be using this to finish up the 6th step from my list in the previous posting [June 21, 2008] towards my goal of a simple test room. I will allow you to select a face and then a material can be applied to it. Internally, this will most likely break the object up by adding another child sub mesh on the fly to it (I will combine them when they share the same material) and then you can use the material browser to select a material to apply. This will actually go a long way towards creating the room. The face removal should be fairly straight forward once I get face selection finished. I also plan to add support for vertex selection as well which should also be fairly straight forward since I will provide a 'helper' interface that has things like 'checkVertexForClick' which will take a matrix, a vertex, and a 'vertex size' which will check to see if a box that gets projected into screen space where the vertex is would be hit by a particular mouse coordinate. Then it should simply be a matter of looping over the vertices and feeding them in to this helper class.

Once these two steps are done, the rest of it should be straight forward implementation things which just require me to have my butt in a chair for a while. All in all, things are going well. The editor is actually shaping up to be something useful. I might just get my work to review it [part of my contract with them] before I make an official release sometime. I will probably also end up taking suggestions and contributions from the community and integrating them into the editor when I get a chance. I still want control over this since I am using this for my own personal project but I will definitely integrate items when it makes sense to do so and release that back.

Success

So it turns out that I actually code a lot more effectively if I have a specific set of tasks to complete. I created a step by step guide to have the basic features required to build a simple test map. The test map is nothing spectacular. It's basically got a box that's been scaled out and had a face cut out of it for a 'connection' to another room. The other room is the same thing of another box with a face cutout that is going to be snapped to the first one. Each box starts with it's normals facing out but I am going to need to invert those so that the walls face in. I am also going to have to be able to assign a texture to each wall. So that's pretty much it. I have a lot of that functionality in there but none of it is really completed. There are a few bugs with each thing but now that I've tasked out everything, I am going through 1 by 1 and making sure everything works as expected before moving on. It's really nice to have a goal to work towards and having something tangible come of it.

Here are the tasks that I've prepared in order to be able to do the test room. This is the order that I have been tackling them since yesterday so hopefully when I am finished, there won't be much else to do.

1. Clear the scene
2. Translate tool
3. Scale tool
4. Box placement
5. Simple normal manipulation [just reverse them for now]
6. Texture assignment [per face or per object]
7. Face removal from a box
8. Vertex snapping
9. Object snapping
10. Light placement [point light]
11. Sprite icons for lights
12. Color adjustment for lights
13. Player start placement
14. 'Trigger' volumes
15. Rotate tool

So I think that should more or less add the required functionality to be able to create the room I want. I think I am going to always sit down, plan out the creation of something, and break it down similarly in the future. It lets me know how long I'll be towards a target, keeps me focused on getting something useful accomplished, not just something cool, and it also gives me a specific feature to drive towards completing at any given time.

That being said, I sat down today and did some actual work. I managed to fix/implement the first 4 features of that today. Granted, almost all of the framework was there but I at least fixed some bugs and made the scale and translate tool function as they are supposed to.

As it stands now, I've given myself the weekends and 2 'work days' throughout the week to be spending on this. I also gave rough estimates for how long things will take. Based on that [which may be horribly inaccurate], it appears that I should have all of this done by mid August some time. As far as that is, I think I can pull it back into late July which will be nice.

As far as the editor is concerned, I won't be recreating Maya/Max at all but I will be allowing for simple face manipulation that will allow you to create a basic room, block off some sections with walls, and place ramps and things so you can have multiple levels. Anything more complicated than that and I'll have to allow you to import it as a mesh from your favorite modeling package. I will have to create a suite of tools to allow you to place objects easily and line things up nicely so that will probably be coming soon as one of the next few use cases.

Scheduling

In my attempt to take a much more professional approach to the creation of my editor, I am actually using some scheduling software. It is called Hansoft and I am using the free license that they give to attempt to manage myself. I find that I am always wandering off the path towards actually getting something usable so in an effort to control that, I will become my own manager.

I just installed it and have been playing around with it for about an hour or so. It seems to support everything I will need: bugs, tasks, and scheduling. Hopefully I will be better at estimating how long features will take so I can be more committed to my release dates when I set them. Currently, I have too much of a 'when it is done' attitude and would like to correct that.

As an addition to this, I am also trying to come up with 'use cases' for the editor. I want to be able to build a test room as my first real milestone for the editor. In order to accomplish that, I am going to strip away all of the unfinished features, tuck them somewhere in a directory on my computer for later, and start fresh and actually finish a feature and flesh it out before I move on. That being said, the goals I have laid out for myself will mean that I can make a basic test map of 2 rooms [just simple cubes] that are snapped together with 2 lights inside as well as having 2 'volumes' inside that will be read in as triggers for the game engine whenever that gets completed. I have given a really rough schedule for this [I will go back and re-evaluate my estimates soon when I'm more rested] and it appears that I should be able to finish all of this by the end of August if I just work on the weekends and 2 days through out the work week. That being said, I am going away for vacation for 1 weekend in July so that will have to be taken into account. At least now I have a more realistic estimate as to how long it will take me which is always a good thing. It's humbling to know that what I want will take me 6 years but what I need will only take me 1 [as a metaphor, not in reality].

I'll probably post a schedule from time to time to show what I am working on, what's currently finished, and so that people can have more of an insight into my own work habits. I will post some more technical details about the tools I am using in an upcoming post.

Refactoring

I have been looking at my code lately and it's time for another refactor. I've noticed that almost all of my SceneObject types require transformations. There are only a select few that do not yet I have implemented the transformation system through the generic property/command system. This worked well at the start but as I implement more complex, non-primitive, types for the editor, I'm realizing that it can be a pain to re-implement the same functionality over and over again.

I am currently working on a BoxTrigger which is composed of a SceneNode and a wireframe box (technically it doesn't require the SceneNode but I need it for later). I want to be able to translate, rotate, and scale this object but in order to do that, I have to forward the methods on to the SceneNode. I'd have to write all sorts of code to handle the transformations again when I really shouldn't have to.

My proposed solution, after looking at Sinbads wxOgreMVC code, is to implement the transforms on the base SceneObject class and then declare a way for each derived type to receive a notification when the transform changes. This will simply allow me to add the 'position', 'scale', and 'orientation' properties to my class and everything else should work.

The tools will need a very small rewrite to handle this but that shouldn't take more than 10 minutes. In order to transform a SceneObject, the tool should first check to see if the any of the 3 properties above are present. If they are, then the associated methods should be relevant. For instance, the translate tool should see if the 'position' property is available. If it is, it can then call 'translate', 'setPosition', 'getWorldPosition', etc knowing that they are fully implemented.

When it comes time to save objects, the transform information may require special handling. I believe that the 'position' property should be all that is required to be written out.

I'm doing some testing at the BoxTrigger level before I implement this at the base level but so far, everything has worked accordingly. I believe this transition should make all future objects a lot easier to implement and work with. Considering that most of the editor objects are concerned with transformation information, having it available at the base level should be a major feature.

A little too quiet

So it's been a few months since I last posted. I got busy with school and living in a house with 4 other people. Let's just say that there was a lot of Halo that happened. Unfortunately, that experience has come to a close. I wrote my last exam today and will be moving out on Sunday. I'll be in my new place with my fiance on Monday/Tuesday which will be our own place where we will stay for a few years. Eventually we're looking at getting a house. I also start my job again (game programmer) in a week and a half.

What this all means is that once the move is done, I will finally be able to work consistently on my projects again. The editor will start getting some much needed love and I am hoping to add a few things into the RTS game.

The main thing that I've been toying around with lately has been a visual scripting system. There are examples of this all over the place lately. The two that I first saw were the editor for the Crytek engine as well as the editor for the Unreal engine. Crytek calls their version FlowGraph with an example below.



I have tried both of the systems in a limited capacity and I just find that the Crytek version is easier to work with and a much nicer interface than Unreal's version. That being said, I haven't actually compared the capabilities of each but I haven't run into anything that I'd want to do that I couldn't in FlowGraph.

I've been experimenting with my own system and I seem to have come up with a reasonable solution. It's heavily based on the Crysis SDK but since I don't have actual source code for it all, I've had to do parts from scratch. I'm hoping that I will be able to implement this system into the RTS so that scripted sequences as well as some basic AI logic could be laid out with this tool.

There are a lot of possibilities that I have in my head for how this system could be used which I will explain in a future post. Needless to say, I will try to make this as powerful as possible so that I don't have to resort to the code-compile-wait-test-debug-wait-redo cycle that a lot of development gets stuck in. If I can chop out the compile part, that should save me a lot of time and at the same time will open up creation to many more people than just coders.

I'm also looking into toLua to expose a lot of the game to Lua so that I can write modules and some AI in lua without having to constantly recompile. At some point, I'd like to be able to define nodes in my visual logic system in Lua so that new functionality could be added on the fly without recompiling all the time.

There are a few other things on the burner right now but I am going to try and finish fixing the transform tools now that I've merged the 'tool' and 'gizmo' system into one system. This will make it a lot more consistent when a new piece of functionality is required.

And now. If you'll excuse me, I am going to get myself back into some coding.

Deformations

Well I am now officially employed back in the game development world once again. I am back working for the same company that hired me for a co-op position last year. I'll be starting in May. So I'm excited about that. I'll still be continuing work on the editor as well as on my game so that shouldn't change.

As for the editor itself, I now have the concept of a 'mode' which will be a distinct state for the editor to be working in. This will help the plugins organize everything that they need in order for their particular 'mode' to work. For instance, the terrain editing mode will disable regular object selection so that you can only manipulate the terrain.

Each mode can have a custom tool window that is queried for, and managed by, the editor whenever that mode gets activated. You can see the terrain tool coming along in the video below, with the higher quality version available. It's tool window is shown in the lower left hand side of the screen which I use to change how I am manipulating the terrain.

Intermediate Terrain Editing from Shawn Carroll on Vimeo.

Terrain Editing

Two new things:

1) I've started working on terrain editing inside of the editor. I think this will be one of the most used features other than direct object placement so I'd like to make sure it's possible to do. I have to come up with a 'mode' system that will allow the editor to reside in certain modes. That is, object placement will be one mode while terrain editing will be another. No two nodes can be active at the same time so that they can be sure that their settings won't be changed while they are on. The switching between modes can appear automatic or manual to the user. If you click on an object to place it, you'll automatically be kicked into the 'object placement' mode. On the other hand, you will have to manually hit an 'edit' button to go into terrain editing mode. It's up to the designer how each of these modes will be activated.

2) I am going to try and upload videos now showing off the editor in action. I find that videos show more than a single static screen shot can. I'll post the videos through Vimeo since it appears to offer the best quality. I'll post the embedded video directly on this blog with a link to the 'higher quality' one on the Vimeo site. The originally will also be available for download on the Vimeo site (bottom right) for each of my videos if you want to save them to your local computer.

And without much further wait, here is my first video showing off the ability to raise terrain in the editor. I used the amazing editable terrain manager which was not written by me for this. I wanted a proof of concept to make sure it would be doable. I have to add proper support but it's running inside of the editor and was able to be interfaced as a plugin which was all I wanted to confirm.

Resource Browsers

I've implemented a system where a SceneObject can add a 'resource' property to the list of editable properties. What this will do is provide a text field as well as a '...' button next to it inside of the PropertyGrid. When the user clicks on the ..., a browser window is opened (all handled through the editor) for the appropriate type of resource. This browser window can then be used to preview and select a new resource that should be linked in. Of course, these browser windows can only handle specific types such as a material or a sound, so they will be able to be plugged in to the editor. When a resource is going to be changed, an appropriate browser is looked up and presented to the user.

So far, I have implemented a browser for Materials which will most likely also work with other types of resources that are built in to Ogre but I have to provide a ResourceFactory for those. It simply defines a type and the ability to query for the name and a preview SceneObject of it.

Example Code

[This is just a temporary theme. I think it's fairly dark so I will either change that or find something to lighten it up.]

I just wanted to post some code to show how working with my properties can work. I've switched them over to use the Any class that is built in to Ogre but originally I was using my own version of it. There is more to a property itself than just the Any instance but a property does have one of them attached called the 'propertyValue'.

Here is the code I use to actually export the properties of *any* SceneObject at all. This works on Entities, ParticleSystems, Lights, and will work on any future thing out there. *All* of the code in the editor is like this. There is no notion of a particular type *anywhere* except inside the actual SceneObject derived classes themselves. So something that works on one SceneObject will work on a completely different type of SceneObject as long as it provides the same properties and commands (commands are 'issued' to the SceneObject through a generic interface). I'll post an example of the translate tool a bit later. But needless to say, I write code once and if it works, it'll work for anything. I know that whenever I implement sounds, the translate tool will work on those without having to touch the code. It's nice being able to expect that.

void XmlSceneExporter::_exportProperties ( SceneObject* rootObject, wxXmlNode* propertiesNode )
{
 SceneObjectPropertyList properties;
 rootObject->getProperties( &properties );

 if( properties.size() == 0 )
  return;

 wxXmlNode* propertiesNode = new wxXmlNode( node, wxXML_ELEMENT_NODE, "properties" );

 size_t numChildren = properties.size();
 for( size_t i = 0; i < numChildren; i++ )
 {
   Any propertyValue = properties[i].getPropertyValue();
   if ( propertyValue.isEmpty() )
     continue;

   String strData;
   if( StringConverter::convertToString( propertyvalue, &strData ) == false )
     continue;

   wxXmlNode* propNode = new wxXmlNode( propertiesNode, wxXML_ELEMENT_NODE, "property" );
   propNode->AddProperty( "name", properties[i].getName() );
   propNode->AddProperty( "value", strValue );
  }
}

And here's the example 'convertToString' that is used. It's all very simplistic. And this will allow future objects to be registered and saved without touching anything else. Just implement a new TypeDescriptor, register it (at run-time) with the TypeDescriptorManager, and you're all set.

bool StringConverter::convertToString( const Any& property, String* strData )
{
 String strValue;
 const TypeDescriptor* descriptor;
 TypeDescriptorManager* mgr = TypeDescriptorManager::getSingletonPtr();

 descriptor = mgr->findTypeDescriptor( propertyValue.getType() );
 if( descriptor != NULL && descriptor->canConvertToString() )
  return descriptor->convertToString( propertyValue, &strValue );

 return false;
}

I am rather enjoying generic programming like this :) I haven't found myself going back to rework old code to fit a new object that I didn't expect to use. Anyways. I have another exam in 8 hours so I guess I'll start studying for it now.

Saving the world, one scene at a time

The conversion of the XmlSceneExporter is now complete. I can now save/load anything that's creatable inside the editor so far. It actually only took me about 2 hours to port it over, write any missing functionality, and test it. I had to change some internal workings in my SceneObject class as well as introduce a new class called a TypeDescriptor since I no longer had the power of .NET's Reflection. The TypeDescriptors are pluggable and they basically provide features for a particular type. For instance, they will provide a convert[To/From]String method so that data can be written to disk and reloaded again. I will be providing basic ones for all of the various things I'll need to save inside of Ogre but they can be plugged in through a plugin which means that people can add new types that are serializable with any existing exporter that uses TypeDescriptors (which will most likely be all of them).

I also revamped the blog style a bit. I will be searching for a better template eventually but for now, I just wanted something different. Anyways. I have a final exam to write in half an hour so I should possibly do something towards that :)

"I like to move it, move it"

The translate tool is done. I had changed how the selection manager was processing events which required some changes to the tools. I also was getting some strange issues with control focus and wxWidgets which ended up getting solved. I had to force the render panel to get focus when it was clicked.

One of the major down falls to switching over was that I wasn't NULL'ing out my pointers in Managed C++ since this was done for me. Now that I'm using C++, this has come back to haunt my debugging dreams. I've made a large pass over the code base and have initialized all my variables in the constructor but there are still some NULLs getting passed around that somehow worked in Managed C++. Who knows. It's all getting solved and it's making the code more stable with every step.

I am going to see about implementing the next plugin which is the Sample Exporter. At least this will let me load up the larger scenes that I had saved before. I'm tired of looking at a single test OgreHead. I am really not sure how I'm going to write out all of the variables right now. With .NET, I could write a converter that would parse from/to a string which meant that I could use this for my PropertyGrid display as well as for writing out to a file. Since C++ doesn't natively support this, I believe I am going to write a 'converter' class which will take a specific type and be able to parse to/from a string. For most types, I can convert *to* a string using Ogre's built in StringConverter class. I'll have to convert back from a string but worse things have happened. I believe once I have this, I'll be able to say Convert::toString( const Any& someObject ) and based on the value returned from Any::getType, I'll be able to match it to a specific converter and it'll be written out. The joy of this is that the exporter won't need to know how to save any particular value. The down side is that in the future, if the converter changes, there isn't really any way to know about it from an exporter point of view. That is, data could be written out with v1.0 of TypeX Converter but then that could be replaced with v2.0 of TypeX Converter which no longer recognizes that particular format. I'm sure I'll think of something other than just crashing :)

It's nice being able to finally put a scene together. Here is my current progress:

Base Editor: 95%

Plugins
--------
Basic Align Tools: 0%
Basic Object Editors: 0%
Properties Window: 0%
Sample Exporter: 0%
Basic Gizmos: 50% - Translate is done, the others are extremely similar to it
Basic Object Factories: 100%
Scene Graph Window: 100%
Resource Browser: 100%

Port Job

The porting is coming along nicely. I've made a few internal changes but nothing huge. The biggest problem I've had is that I had tons of memory leaks. I have removed all of them so far. The editor starts up and exits cleanly from start to finish. I still have to figure out how to handle exceptions better since once one happens, the app usually crashes and burns. This is going to be an issue between exceptions and wxWidgets but I'll get there.

I've completed the following plugins:

Scene Graph Tree
Resource Browser
Basic Object Factories

and am working on the Gizmos plugin which contains the translate/rotate/scale tools that will be provided. I will have to overhaul the UI once the porting is done to make it nicer to look at. Right now, I'm concerned with getting it functional to where it was with .NET/CLI C++
