Hi,
Many of you know more about OpenGL than I so I'll ask a question. I'm slowly learning but I've yet to see an answer to what I'd like to do. I want at times to render a Sprite in black and white that is normally in colour. I'll assume for now I'm using textures as the Sprite images (SPGL).
Is this possible, is it easy, and most importantly does it make sense? I could also have a second set of textures that are of course already black and white and switch at runtime those I render to the screen. This is not too inelegant a solution.
Thanks for your help,
Bill
