Detailed Description

Semi-abstract base class for distance metrics.

Distance measurement plays an extremely important role in skeletal implicit surfaces. Indeed a skeletal implicit surface is essentially an offset surface. This class abstracts the notion of distance measure into a function given a displacement vector. In this manner any distance measure can be implemented in a sub class and applied in a BlobTree.

This base class implements euclidean distance measures.
