NAME

data_set_filter - abstract class for visualization pipeline filters.

DESCRIPTION

Data_set_filter is an abstract class that provides methods and data structures for the various data set pipeline filters. The data_set_filter takes as input a data set (e.g., visage_data_set, plot3d_data_set, etc.) and generates a data set on output. This differs from computed_feature that generates a display_data on output, or the display_filter that takes display_data as input and generates display_data as output.

SUPERCLASS

computed_feature

INSTANCE VARIABLES

data_in the name of the visage_data_set or another data_set_filter that is used as input.

data_out the name of the visage_data_set that is the output. If no name is given than one is automatically generated as necessary.

MESSAGES

data_in=data_set sets the name of the visage_data_set to be used.

data_in? returns the name of the input visage_data_set.

data_out=data_set sets the name of the output visage_data_set. This can be equal to data_in if overwriting data is desired.

data_out? returns the name of the output visage_data_set.

create_data_out! Creates the output visage_data_set.

EXAMPLE

Refer to specific classes for examples (e.g., delaunay).
