## Detailed Description

template<typename GridT = Vec3fGrid, typename PointListT = std::vector<typename GridT::ValueType>, bool StaggeredVelocity = false, typename InterrupterType = util::NullInterrupter>
class openvdb::v9_0::tools::PointAdvect< GridT, PointListT, StaggeredVelocity, InterrupterType >

Performs passive or constrained advection of points in a velocity field represented by an OpenVDB grid and an optional closest-point-transform (CPT) represented in another OpenVDB grid. Note the CPT is assumed to be in world coordinates and NOT index coordinates! Supports both collocated velocity grids and staggered velocity grids

The `PointListT` template argument refers to any class with the following interface (e.g., std::vector<openvdb::Vec3f>):

class PointList {
...
public:
using value_type = internal_vector3_type; // must support [] component access
openvdb::Index size() const; // number of points in list
value_type& operator[](int n); // world space position of nth point
};
openvdb::v9_0::tools::PointList
std::unique_ptr< openvdb::Vec3s[]> PointList
Point and primitive list types.

Note
  All methods (except size) are assumed to be thread-safe and the positions are returned as non-const references since the advection method needs to modify them!
