## Functions

template<typename GridT, typename RandGenT = std::mt19937, typename PositionArrayT = TypedAttributeArray<Vec3f, NullCodec>, typename PointDataGridT = Grid< typename points::TreeConverter<typename GridT::TreeType>::Type>, typename InterrupterT = util::NullInterrupter>
PointDataGridT::Ptr | uniformPointScatter (const GridT &grid, const Index64 count, const unsigned int seed=0, const float spread=1.0f, InterrupterT *interrupter=nullptr)
| The free functions depend on the following class:
template<typename GridT, typename RandGenT = std::mt19937, typename PositionArrayT = TypedAttributeArray<Vec3f, NullCodec>, typename PointDataGridT = Grid< typename points::TreeConverter<typename GridT::TreeType>::Type>, typename InterrupterT = util::NullInterrupter>
PointDataGridT::Ptr | denseUniformPointScatter (const GridT &grid, const float pointsPerVoxel, const unsigned int seed=0, const float spread=1.0f, InterrupterT *interrupter=nullptr)
| Uniformly scatter a fixed number of points per active voxel. If the pointsPerVoxel value provided is a fractional value, each voxel calculates a delta value of how likely it is to contain an extra point.
template<typename GridT, typename RandGenT = std::mt19937, typename PositionArrayT = TypedAttributeArray<Vec3f, NullCodec>, typename PointDataGridT = Grid< typename points::TreeConverter<typename GridT::TreeType>::Type>, typename InterrupterT = util::NullInterrupter>
PointDataGridT::Ptr | nonUniformPointScatter (const GridT &grid, const float pointsPerVoxel, const unsigned int seed=0, const float spread=1.0f, InterrupterT *interrupter=nullptr)
| Non uniformly scatter points per active voxel. The pointsPerVoxel value is used to weight each grids cell value to compute a fixed number of points for every active voxel. If the computed result is a fractional value, each voxel calculates a delta value of how likely it is to contain an extra point.
