The ray_trace_mode tracing mechanism operates at a per-pixel level. Thus, to get a small image with a nice outline, you simply render a large image and then shrink it down.
The black outline made by "set ray_trace_mode, 1 (or 2, 3)" is very nice if the picture is a zoom in view. However, when I look at a whole structure, a big one, the black outline is way too thick and the loops just turn into some thick black lines. Is there a way to adjust the thickness of the black outline in the ray-traced image?
