>>54577339This is what you call a height map... So, not even something geometrical, just information on a flat, low poly surface to reflect light differently, emulating geometry. The wire frame is couple triangles still.
Somebody took the initial high poly model into Zbrush, busted it up a lil bit, then baked a map out of it. It's one of the texture layers, along with colors and stuff like that. 2005 mainstream practice.
