performs ray integration with pre-integration tables.
vtkUnstructuredGridPreIntegration performs ray integration by looking into a precomputed table. The result should be equivalent to that computed by vtkUnstructuredGridLinearRayIntegrator and vtkUnstructuredGridPartialPreIntegration, but faster than either one. The pre-integration algorithm was first introduced by Roettger, Kraus, and Ertl in "Hardware-Accelerated Volume And Isosurface Rendering Based
On Cell-Projection."
Due to table size limitations, a table can only be indexed by independent scalars. Thus, dependent scalars are not supported.
