Detailed Description

template<typename PointAccessorType, typename RandomGenerator, typename InterruptType = util::NullInterrupter>
class openvdb::v5_2::tools::NonUniformPointScatter< PointAccessorType, RandomGenerator, InterruptType >

Non-uniform scatters of point in the active voxels. The local point count is implicitly defined as a product of of a global density (called pointsPerVolume) and the local voxel (or tile) value.

Note
This scattering technique can be significantly slower than a uniform scattering since its computational complexity is proportional to the active voxel (and tile) count.
