Summary:
For real-time collision detection, signed distance fields are a pretty commonly used primitive, since vertex-signed distance tests are O(1) and volumetric representations tend to be more robust to interpenetration than meshes.

This is the actual implementation of the volume with interpolation and gradient calculation; actually creating them will come in later diffs.
