NAME

point_based_filter - abstract class data_in to be either display_data or data_set

DESCRIPTION

Point_based_filter is an abstract class that allows the input of either display_data (or display_filters) or data sets (or data_set_filters). Subclasses of point based filters only deal with the input point data, and ignore any other topological information.

The behavior of subclasses of point_based_filter is as follows. If the input is a visage_data_set, and scalar and vector visibility is on, the subclass operates on the visage_data_set scalar and vector. If the input is display_data, the subclass operates on the display_data scalars and either 1) the normals or 2) vectors. order. Whether normals or vectors are supplied depends upon whether which of the two are present, if any. If both are present, normals are supllied as the vector input for the subclasses of point_based_filter.
