## Detailed Description

template<typename CptGridT = Vec3fGrid>
class openvdb::v12_1::tools::ClosestPointProjector< CptGridT >

Class that holds a Vec3 grid, to be interpreted as the closest point to a constraint surface. Supports a method to allow a point to be projected onto the closest point on the constraint surface. Uses Caching.
