Two questions ... read please :D


How do I avoid using auto-texture-coord generation (how to calc tex coords)?


How do I implement Detail Texturing while using auto-tex-coord generation?

Lot of thanks
and sorry about my english.

First question : that’s easy ! Just specify your texcoords with glTexCoord2f (or glTexCoord2fv or glTexCoordPointer…).
To disable texcoord generation (anyway it’s off by default), call :
glDisable (GL_TEXTURE_GEN_S);
glDisable (GL_TEXTURE_GEN_T);

Second question : I couldn’t give you a complete answer since I’ve never tried detail texturing. Maybe you could look on the Extension Registry somewhere on this site. It’s a catalogue of all opengl extensions, with many explanations on each.


Detail texturing is just applying a second texture that is tiled very often.

Just enable blending, choose a blending function, select your texture, and alter the texture matrix using glScale.
