Re: [isugamedev-devel] changing colors of textures

[Josh B. <br...@vr...>]

I think the fastest way to do what I want to do is to draw the object
using primitives in OpenGL and store it into a display list.  This of
course only works if you can change the color of an object that is in the
display list, is there a way to do that?  If not I'll just store all
objects of all different colors in display lists and have a look up
function for the correct object for what I need to draw.
