TrilinearTraits< ValueT, Staggered > Struct Template Reference

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...
