Data Visualization Classes

This subsection details the instances used to process and manipulate the source data. The typical usage of some of the classes is also shown. See Section B.5 for sample images generated with these classes.

One point to note is that the source can either be point or cell data. If the source is cell data, a conversion to point data may or may not be required, in order for the object to be rendered correctly. If a conversion is needed, the 'cell_to_point' flag (see below) must be set to 'True', otherwise to 'False' (which is the default). On occasions, an inaccurate object may be rendered from cell data even after conversion.
