class  UniformPointScatter< PointAccessorType, RandomGenerator, InterruptType >
 The two point scatters UniformPointScatter and NonUniformPointScatter depend on the following two classes: More...
 
class  DenseUniformPointScatter< PointAccessorType, RandomGenerator, InterruptType >
 Scatters a fixed (and integer) number of points in all active voxels and tiles. More...
 
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...

Detailed Description

We offer three different algorithms (each in its own class) for scattering of points in active voxels:

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.
