(...) If you want a visual example on stipple, look at my LD4DStudio, it uses it for transparent stuff.

(...) In order for GL_DEPTH_TEST to work, you have to clear the depth buffer at the same time you clear the rest of the screen: glClearDepth(1.0); glClearColor(0.0, 0.0, 0.0, 0.0); glClear(GLCOLORBUFFERBIT GLDEPTHBUFFERBIT); (Note: the (...) (15 years ago, 31-Mar-10, to lugnet.cad.dev, FTX)

(...) I see.. but problem is that if I use glEnable(GL_DEPTH_TEST) then my polygons won't render at all. Tutorials related to OpenGL explicitly told not to use GL_DEPTH_TEST because of this.. how did you avoid it? (15 years ago, 31-Mar-10, to lugnet.cad, FTX)

(...) 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)

(...) If you prefer not to sort at all you can use glEnable(GL_POLYGON_STIPPLE) for transparent polygons. It doesn't look nearly as good, but it's really easy to code. Have fun, Don (15 years ago, 31-Mar-10, to lugnet.cad, FTX)
