DVextr_cell_comp extracts one cell_data component from each Cell_Data cell_set. If there are multiple Cell_Data cell_sets, the same component is extracted from each cell_set. DVextr_cell_comp is the cell data equivalent of DVextract_comp for node data.
Since the renderer draws just the first component it finds in each cell_set, you use DVextr_cell_comp to obtain the right component from a multi-component Cell_Data field.
A reference to a field that contains a Mesh and Cell_Data.
An integer that specifies which component (0-n) to extract. This is often obtained from a combination of a UIradioBoxLabels and the DVcell_data_labels base module.
The output is a reference to a merged object that contains the new Cell_Data, plus references to all other unchanged objects in the input Mesh.
