Detailed Description

template<typename TreeT, typename RayT, int ChildNodeLevel>
class openvdb::v5_2::math::VolumeHDDA< TreeT, RayT, ChildNodeLevel >

Helper class that implements Hierarchical Digital Differential Analyzers for ray intersections against a generic volume.

The template argument ChildNodeLevel specifies the entry upper node level used for the hierarchical ray-marching. The final lowest level is always the leaf node level, i.e. not the voxel level!

ListType is a list of RayType::TimeSpan and is required to have the two methods: clear() and push_back(). Thus, it could be std::vector<typename RayType::TimeSpan> or std::deque<typename RayType::TimeSpan>.
