Hi! I''m just wondering if it''s possible using some commands in OpenGL to mix 2 texture maps together. Meaning, I load an image as the base texture and then load another one to affect only one of the color components (i.e. like only loading it to affect the alpha values of the first texture)?
Is there some command to achieve this? The only way I''ve figured out so far is to edit the actual bits of the first texture. Is there a better way?
SGI recently moved their extension registry to their open source site. Here''s the link:
although ARB_MULTITEXTURE doesn''t seem to be there. Michael Gold (of NVIDIA) has a list of the extensions their chips support. It has a short description of ARB_MULTITEXTURE, a link to the spec, and an example program.
