 | | My attempts to get a vector line drawing —Eric Albrecht
|
| | | For various reasons, I've been attempting to extract a vector line drawing of a large LDraw model. On the surface, this would seem simple (which is always the case for the hardest projects). LDraw itself is a vector format. Each edge line is defined (...) (13 years ago, 23-May-11, to lugnet.cad, FTX)

This way the (OpenGL) 'Z-Buffer' does all the hard work for you. Maybe travis could implement it in LDView, (or (...) (13 years ago, 23-May-11, to lugnet.cad, FTX)

Every angle of white reflecting to the camera is actually a different shade of gray. I really want no shading (...) (13 years ago, 23-May-11, to lugnet.cad, FTX)

| | | | (...) Wow do I feel stupid. No, I hadn't tried that, and it works perfectly. It's still not a vector image, but at least it gets me to a good raster image in one step instead of five. It is a bit counter-intuitive to me that the way to get a good (...) (13 years ago, 24-May-11, to lugnet.cad, FTX)

| | | | | | (...) Hey, this is interesting. Is it actually just drawing the visible lines in some final rendering stage? Or is there more going on there with the Stencil and/or Depth buffer? (13 years ago, 24-May-11, to lugnet.cad, FTX)

| | | | | | (...) (FUT lugnet.cad.dev) I draw everything but the edge lines with glColorMask() set to all false. This updates the depth buffer, but doesn't update the color buffer. Edge lines are drawn with a standard glColorMask(). --Travis (13 years ago, 25-May-11, to lugnet.cad, FTX)
