OpenGL obj renderer

This is an early state of my OpenGL 2.2 loader/parser/renderer for .obj files. It uses VBO's for the modeldata, and DLs for material infos. It supports multiple materials per model, lights and reflection maps. I need to add support for transparancy and attaching models to each other and animating them. When that is done, I'll begin writing the game. Implemented in C using SDL and OpenGL, captured with glc. IDE: CodeBloack, OS: Linux, Also runs on Windows.
It runs 100% smooth, and with 0% cpu load when rendering a 1.4 MiB model. For some reason the capture is kind of laggy though..

Veree nais.

I have an OBJ loader on an engine I'm working on, and I have decided to ween myself of the old and into the new. (built in uniforms, you will be missed).

They way it is now is containers for normals, vertex and uvs. And indices sorted in groups -> faces.

Offcourse, the buffer messes up the indices i heard, so I'm currently reading about making a second VBO for the indices. (Moving from 2.0 to =>3.1 is confusing but well due its time)

How did you handle the datastructures?

@slitor I'm storing each object in a VBO as interlaced triangles

[slitor]

@DusteDdekay Is that, objects as groups/sections of a model or do you mean the entire mesh?

[DusteDdekay]

@slitor An entire obj file, my "engine" is very simple, and so, to make an "object" with movable parts, multiple .obj files would have to be loaded and attached together via the scene graph. To avoid myself loosing my breath, I chose to see objects with the same amount of simplicity as sprites, just in 3D, for now until I become better.

Very nice! Makes my object loader look like crap :-P

[DusteDdekay]

@jamwaffles Don't worry about that, 99% of the stuff I see around makes this look like it was done by a child in kindergarden with downs.. While sleep-typing.. In 30 minutes.. But well, coding is food for your soul, and about personal development and discovery, don't ever compare yourself with others, it'll only make you feel bad.

Neat! Is the source available somewhere?

Mmmmm delicious OpenGL.
