class openvdb::v7_1::tools::LevelSetRayIntersector< GridT, SearchImplT, NodeLevel, RayT >
This class provides the public API for intersecting a ray with a narrowband level set.
It wraps a SearchImplT with a simple public API and performs the actual hierarchical tree node and voxel traversal.
 Warning
 Use the (default) copyconstructor to make sure each computational thread has their own instance of this class. This is important since the SearchImplT contains a ValueAccessor that is not threadsafe. However copying is very efficient.
