I would like to use a few simple 3d diagrams in my LaTeX document. They primarily consist of polyline segments in 3d, along with an occasional simple surface (e.g. paraboloid). There are two questions:
1) Is there a good way to draw polylines in 3d that conveys the depth? I thought about fading based on distance from the eye, and also of shadows of the drawing on the coordinate planes, but I am not sure how well it'd work in practice. I'd love hear how others solved this/see some examples that I can imitate.
2) What are the drawing packages that are compatible with LaTeX that would make the task of drawing easier. I know of asymptote which can draw parametric 3d surfaces, but are there others?
