Hi !

Could somebody explain me the difference between GL_MODULATE and GL_BLEND ?

Thank you !


Texture Environments and Texture Functions

p.s. Any 3D chip supports GL_MODULATE, but only few can do GL_BLEND in hardware.

Actually, quite the reverse. Blending is far more common, and only really low-end cards (among them are some of the earlier ATI Rage cards) don’t support multitexturing. Most of the cards that do multitexturing can only do 2 at a time though… not that you could make use of more, really nVidia’s GeForce3 and most (maybe :P) industrial cards have 4 or more TMUs.

just search in here, we had a discussion about this topic last week…
