It is possible to define new 2D graphics primitives using PostScript.
This is how the Graphics`Arrow` package works.
But does the user have any control over how 3D graphics are rendered? Is
is possible to add new primitives, for example a line whose width
depends on the distance from the ViewPoint (but not the viewing angle)?
A series of joined lines with varying thickness appears ugly. A polygon
would be a more appropriate low-level representation for a line whose
thickness changes linearly. But a 3D polygon appears differently from
different angles, and one would need access to the mechanism of
translating 3D graphics to a 2D projection to be able to use a 2D polygon.
Any suggestions for achieving this effect?
