The internalFormat comes from our use of glTexImage*D, so the OpenGL docs for glTexImage2D are very useful: http://www.opengl.org/documentation/specs/man_pages/hardcopy/GL/html/gl/teximage2d.html > What conversion takes place in the driver if sourceFormat is (say) GL_RGB8 > and the internalTextureFormat is GL_RGB32F? No mention of GL_RGB32F in the above docs though.... but this is rather a late addition to the family, so you'd probably have to look at OpenGL extension registry or OpenGL 2.x/3.0 docs for an answer.
