These are some old OpenGL screenshots of some work that I delivered at one of my previous jobs. Everything here is rendered with GL_TRIANGLE_STRIPS with every triangle colored via 1D texture mapping. This is using the fixed function pipeline instead of shaders (this was in 2004!!). I don’t think many systems around the office at that time were on the bleeding edge.
I REALLY REALLY would like to get back in the OpenGL game using shaders.
