I recently fixed a few problems with my 3d engine and came accross another. I have been updating my 3ds loader. Before my engine only used texture maps, every object had a texture map or wass assigned the default. No problems so far but I want a color texture, no image just the color. Defined by diffuse, spectacular, and so on. Can I create a texture out of just color info and address it like a image texutre:

glBindTexture(GL_TEXTURE_2D, TextureID);

Would just texture maps be enough or would color textures be needed for particle effects like fire, snow, or rain?

Either disable texturing (glDisable(GL_TEXTURE)) before drawing elements that should have simple material based coloring, or create a 1x1 pixel completely white texture and use that (since by default, a fragment that has texturing disabled is also white).

Yes, I guess color textures are a requirement for particle effects, since color textures may also contain alpha values, so you can for example fade out the border of your particle quad. Consider the same without texturing: your particles will be single colored, all solid, which probably looks kinda weird.

You've got a point there ;) They indeed were cool back then ;o)
