Detailed Description

prepare data object for volume rendering

vtkVolumeRepresentationPreprocessor prepares data objects for volume rendering. If the data object is a data set, then the set is passed through a vtkDataSetTriangleFilter before being output as a vtkUnstructuredGrid. If the data object is a multiblock dataset with at least one unstructured grid leaf node, then the unstructured grid is extracted using vtkExtractBlock before being passed to the vtkDataSetTriangleFilter. If the multiblock dataset contains more than one unstructured grid, the ExtractedBlockIndex property may by set to indicate which unstructured grid to volume render. The TetrahedraOnly property may be set and it will be passed to the vtkDataSetTriangleFilter.
