Well, I’m lost. Don’t have a clue how to even start and what everyone is talking about.
What I like to know is some answers to my light questions.
Is this just something like calling glColor3f(…); before glVertex3f(…); ?
These are just textures too, right?
Do I need to use multitextures, or can I place the 2nd texture over the old with some blend function. Or does the texture need a alpha channel too?
any other methods I need to know about?
maybe anyone can hint me on how to create something like this:
the camera is in a cube and three light balls (one red, one green, one blue) are moving with a nice sin function movement through the cube. What’s the best way to get the red, green, blue lights on the walls of the cube and blend the lights together when the lights overlap, or something like that.
