- I am trying to implement an interpolation algorthim over 3D space by
- using a "grid" of tetrahedrons. What I need to compute is a complete
- tiling of 3-space with unit length tetrahedrons: ie, given an XYZ
- location, identify the four points of the tetrahedron that encloses
- that location in this "packed" space. Obviously any offset or rotation
- of this packing "solution" is also a solution, but I don't care which
- particular tiling I compute as long as it is constant.
-
- Where would I look to solve this problem? Computational geometry
- books? I've already sat down with pencil and paper, and have also
- made about 10 oragami paper solids. This problem looked pretty simple
- when I first started it, but it seems like an elegant solution is
- eluding me. :-(
-
- If anyone can point me to any references for this kind of tiling, or
- by sheer chance have an algorithm (hah!) I'd appreciate any help you
- can give me. Thanks!
