- I am sure I am missing something, but I open myself to abuse by asking a
- potentially stupid question:
-
- How do you draw lines, arcs, or other curves in the 3Dkit?
-
- I thought RenderMan would have a standard way to get "zero thickness" objects
- like the way PostScript has strokes of 0 width -- It does the finest line
- possible on the device. But the "RenderMan Companion" doesn't act like people
- draw lines, and I am confused.
-
- Do I just do PostScript, pumping my own points through the 3DCamera's
- transform? Use small cylinders? Polygons?
-
- Please no news on The Theory of Renderman, etc. I understand the high-end
- goals. But I was under the impression that the 3Dkit would do a lot of the 3D
- transforms for me. People even said, "Think of it as 3D PostScript".
-
- I hope I'm missing something.
