Ray-tracing and 3-D objects representation in the BCC and FCC grids

Abstract
This paper describes a ray-tracing and an object description method for objects sampled not in the usual cubic grid, but in BCC (Body Centered Cubic) and FCC (Face Centered Cubic) grids, which are well known in crystallography. The use of this kind of grids is motivated by their interesting characteristics: they reduce the density of samples needed to represent a signal without information loss and they have better topological properties than the cubic grid.
