Classes
struct	TrilinearTraits< ValueT, Staggered >
	Traits for staggered (MAC) trilinear rasterization. This method only works on scalar or Vec3 attribute types and only ever returns a Vec3 tree. It is typically used for velocity rasterization in fluid simulations to avoid the pressure-velocity decoupling problem that occurs on collocated (cell-centered) grids. The resulting Vec3 tree effectively represents the velocity values on the cell faces rather than the cell centers. More...
struct	TrilinearTraits< ValueT, false >
	Traits for collocated, cell-centered rasterization. Work for any scalar, vector or matrix attribute. Note that integer values are interpolated at their respective floating point precision and returned as trees at that precision. More...

Functions
template<bool Staggered, typename ValueT, typename FilterT = NullFilter, typename PointDataTreeT = PointDataTree>
auto	rasterizeTrilinear (const PointDataTreeT &points, const std::string &attribute, const FilterT &filter=NullFilter())
	Perform weighted trilinear rasterization of all points within a voxel. This method takes and returns a tree i.e. ignores grid transformations.
