Shape3ds - 3ds shapes for TGE

Download Code File

Here is a precompiled version (based off 7/30/04 HEAD).

Usage:
* Install the code using the directions below
* Copy a .3ds file and any corresponding textures into your \data\shapes\ folder
* Open up the mission of your choice and hit F11 for the Mission Editor, then F4 for the World Editor Creator, drill
down into Static Objects and drill down into the path of your .3ds file. Click on it and it should be added to the
mission!

Important Notes:
* Texture names are limited to 8.3 (it is an old format)
* You *must* assign a material to any face that you want to be rendered
* If a texture is not assigned to a material then the diffuse color is used to color the material
* Transparency can be used with png textures
* To add a collision mesh simply start the name of the object with "Col-" (i.e. Col-1). There are no hard limits
on the number of these you can use.
* The collision meshes *must* convex (no creases) and *must* be closed (no holes)
* If the mesh is rendering oddly try resetting the pivot points to their default locations

Useful Rendering Modes:
* %obj.showMesh(bool) - hides/reveals the mesh
* %obj.showCollision(bool) - renders/hides the collision meshes
* %obj.showEdges(bool) - renders/hides the edges (green = convex or coplanar, blue = not shared, red = concave)
* %obj.showNormals(bool) - render the vertex normals

Future:
* Load collision meshes into a bsp for much faster results
* Basic animation support
* Make use of ResourceManager properly
* Lighting/shadowing properly

Installation:
* Copy shape3ds.cc/.h into anywhere in the engine folder (like TGE\engine\game\)
* Add them to your project/solution in the IDE of your choice
* Add the lines below to your code
