NAME

abstract_geometry - abstract class for geometry sub- classes

DESCRIPTION

Abstract_geometry is an abstract class that provides private variables and methods for its geometry subclasses. Abstract_geometry is never instantiated.

SUPERCLASS

visage_data

INSTANCE VARIABLES

(Inherited from superclass.)

MESSAGES

bounds?, bbox? retrieve the bounding box of the geometry.

center? Get the center point of the geometry.

length? Get the length of the geometry.

compute_bounds! Cause the geometry to compute its bounding box.

compute_center! Cause the geometry to compute its center.

compute_length! Cause the geometry to compute its length.

compute_properties! convienience routine which sends "compute_bounds!", "compute_center!", and "compute_length!" messages to itself.

EXAMPLE

See various subclasses (display_data, structured and unstructured point and grid sets).
