NAME

visage_display - an abstract class for the various VISAGE displays

DESCRIPTION

Visage_display is an abstract class that provides many methods for controlling the instance variables of its many subclasses.

Visage_display is never instantiated. Instead the methods here are utilized by the subclasses.

SUPERCLASS

object

INSTANCE VARIABLES

visibility indicates the visibility of the object. A value = 0.0 and the object is off.

scalar_visibility indicates the visibility of the scalar data. A value = 0.0 and the scalar data is off.

vector_visibility indicates the visibility of the vector data. A value = 0.0 and the vector data is off.

MESSAGES

visibility= value Set the visibility value.

visibility? Get the visibility value.

on! Turn the object on. It will display itself again.

off! Turn the object off. It will not be drawn.

scalar_visibility= value Set the scalar visibility value.

scalar_visibility? Get the scalar visibility value.

scalar_data_on! Turn on coloring by scalar data. A display will be colored if it can color itself using scalar data, and if scalar data is available.

scalar_data_off! Turn off coloring by scalar data. Then the color property will color the display.

vector_visibility= value Set the vector visibility value.

vector_visibility? Get the vector visibility value.

vector_data_on! Turn on warping by vector data. A display will be warped if it can modify its geometry using vector data, and if vector data is available.

vector_data_off! Turn off warping by vector data.
