Detailed Description

template<std::size_t NDIM>
class madness::SignedDFInterface< NDIM >

The interface for a signed distance function (sdf).

A class implementing this interface will need to provide the sdf given a point in coordinate space, and also the gradient of the sdf at this point.

NDIM is the dimensionality of the coordinate space.
