Title
Body
What are good hashing functions (fast, good distribution, few collisions) for hashing 2d and 3d vectors composed of IEEE 32bit floats. I assume general 3d vectors, but algorithms assuming normals (always in [-1,1]) are also welcome. I also do not fear bit-manipulation as IEEE floats are alsways IEEE floats. Another more general problem is hashing an Nd float-vector, where N is quite small (3-12) and constant but not known at compile time. At the moment I just take these floats as uints and XOR them together, which is probably not the best solution.
