All Implemented Interfaces:

java.lang.Cloneable, PsUpdateIf, java.io.Serializable

public final class PvScene

extends PsObject

Container class for display. This class holds a set of geometries of class PvGeometry. Each PgGeometry registered in a PvDisplay is stored in the PvScene class associated with the display.

Version:

02.07.00, 2.10 revised (kp) Maximal number of registered geometries now automatically adjusted if necessary.
09.04.00, 2.00 revised (kp) Renamed to PvScene from PvPaint.
21.06.99, 1.02 revised (kp) Clipping activated.
02.01.99, 1.01 revised (kp) Additional integer argument for setList calls.
00.00.97, 1.00 created (kp)

Method Summary

void	addGeometry(jv.viewer.PvGeometry aGeometry) Register geometry to be displayed
boolean	containsGeometry(PgGeometryIf aGeometry) Checks whether geometry is registered in PvGeometry
PdVector[]	getBounds() Compute bounding box of all items in the scene, or return null if no items available.
double	getDiameter() Compute diameter if scene has items, otherwise return 0
void	init() If instance has missing name then assign default name 'object_NUMBER' where number is the total number of already created instances.
void	paint(java.awt.Graphics g, PvDisplayIf disp)
jv.viewer.PvGeometry	removeGeometry(jv.viewer.PvGeometry aGeometry) Remove geometry from list of registered geometries and return new current geometry container.

Constructor.

Method Detail

init

public void init()

Description copied from class: PsObject

If instance has missing name then assign default name 'object_NUMBER' where number is the total number of already created instances.

Overrides:

init in class PsObject

addGeometry

public void addGeometry(jv.viewer.PvGeometry aGeometry)

Register geometry to be displayed

removeGeometry

public jv.viewer.PvGeometry removeGeometry(jv.viewer.PvGeometry aGeometry)

Remove geometry from list of registered geometries and return new current geometry container. The current geometry changes if it was the removed geometry.

Remark: (Internal Note) The internal index of the current geometry also changes if it was the last one in the geometry array.

Returns:

PvGeometry new current geometry container

selectGeometry

public void selectGeometry(jv.viewer.PvGeometry aGeometry)

containsGeometry

public boolean containsGeometry(PgGeometryIf aGeometry)

Checks whether geometry is registered in PvGeometry

setState

public void setState(int aKey,
                     boolean aState)

getBounds

public PdVector[] getBounds()

Compute bounding box of all items in the scene, or return null if no items available. All items are multiplied with their modelling matrix before bounding box calculation.

getDiameter

public double getDiameter()

Compute diameter if scene has items, otherwise return 0

update

public boolean update(java.lang.Object event)

Update the class whenever a child has changed. Method is usually invoked from the children.

Overrides:

update in class PsObject

paint

public void paint(java.awt.Graphics g,
                  PvDisplayIf disp)
