Syntax

template<class TriangleMeshType>
class TFastWindingTree

Remarks

Fast Mesh Winding Number extension to a TMeshAABBTree3. This class is an "add-on" to the AABBTree, that can compute the Fast Mesh Winding Number. This calculation requires a precomputation pass where information is cached at each tree node.
