Thank you for the reference. I am playing with F-rep (implicit
representation) that Doug has mentioned elsewhere. I have implemented simple
modelling and rendering techniques using just OpenSCAD language. It is
certainly not efficient that way but promising. Here is an example of a
twist of a holed cube:
The twisted hole was made in the F-rep form. The vertical hole was done by
CGAL from regular OpenSCAD cylinder. Imagine do that with B-rep directly...
Note that voxel based methods leads naturally to bounding box benefits. The
edges in the above image are rough because I have not implemented a feature
recognition method like a B-rep boolean operation inside a voxel.
