programs/raytr

[up]
I present here a simple program realizing 3D scenes. It uses ray-tracing
method. It was used to generate animations of two surfaces, spanned on some
curves. In both cases, when the surface is moving it contains all points in
3D space (plus infinity), each exactly once (excluding the boundary, which
is on each surface). The first surface is spanned on two circles and has
some connections with Hopf fibration (points of one colour on one surface
are arranged in circle, all circles are disjoint and every point of S^3 is
on some circle). The second surface is spanned on the trefoil knot.
