class	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. More...

1) UniformPointScatter. Has two modes: Either randomly distributes a fixed number of points into the active voxels, or the user can specify a fixed probability of having a points per unit of volume.

2) DenseUniformPointScatter. Randomly distributes points into active voxels using a fixed number of points per voxel.

3) NonIniformPointScatter. Define the local probability of having a point in a voxel as the product of a global density and the value of the voxel itself.
