(...) For transparency, LDView sorts triangles, and only triangles, not parts. So the centroid of each triangle is (p1 + p2 + p3) * (1/3). All transparent geometry in the whole model goes into one big list of triangles. While I'm at it, I calculate (...) (15 years ago, 31-Mar-10, to lugnet.cad.dev, FTX)

(...) The only polygons that LDView sorts are transparent ones. Everything else is handled by the OpenGL depth buffer (glEnable(GL_DEPTH_TEST), followed by glDepthFunc(GL_LEQUAL)). Transparent polygons need to be sorted before being drawn, and (...) (15 years ago, 31-Mar-10, to lugnet.cad, FTX)
