Detailed Description

template<miUint DIM>
class mi::shader_v3::Map_distance< DIM >

Map_distance<DIM> class. The Map_distance class is an interface template class, which defines all the virtual methods of Map_distance_base class except the distance from an element. The distance from a bounding box is quadratic.
