Class TransformedObjectPainter<T>

java.lang.Object

de.javagl.viewer.TransformedObjectPainter<T>

Type Parameters:

T - The type of the painted objects

All Implemented Interfaces:

ObjectPainter<T>

public final class TransformedObjectPainter<T>
extends java.lang.Object
implements ObjectPainter<T>

Implementation of an ObjectPainter that delegates the painting to another ObjectPainter, and allows setting an additional transform.

Constructor Detail

TransformedObjectPainter

public TransformedObjectPainter(ObjectPainter<T> delegatePainter)

Creates a new transformed object painter

Parameters:

delegatePainter - The delegate

TransformedObjectPainter

public TransformedObjectPainter(ObjectPainter<T> delegatePainter,
                                java.util.function.BiConsumer<T,java.awt.geom.AffineTransform> transformUpdate)

Creates a new transformed object painter

Parameters:

delegatePainter - The delegate

transformUpdate - The optional transform update

Method Detail

setTransform

public void setTransform(java.awt.geom.AffineTransform transform)

Set the transform that this painter should apply to be the same as the given one.

Note: If the transform update function that was given in the constructor was not null, then this transform will be ignored.

Parameters:

transform - The transform

paint

public void paint(java.awt.Graphics2D g,
                  java.awt.geom.AffineTransform worldToScreen,
                  double w,
                  double h,
                  T object)

Description copied from interface: ObjectPainter

Perform the painting operations for the given object on the given Graphics.

See Painter.paint(Graphics2D, AffineTransform, double, double) for more information about how the Graphics object is handled among painters.

Specified by:

paint in interface ObjectPainter<T>

Parameters:

g - The Graphics used for painting

worldToScreen - The world-to-screen transform. This transform encapsulates the translation, rotation and scaling of the viewer to which this painter belongs.

w - The width of the area, in screen coordinates, in which this painter operates. This is the screen size of the viewer to which this painter belongs.

h - The height of the area, in screen coordinates, in which this painter operates. This is the screen size of the viewer to which this painter belongs.

object - The object to paint. One has to assume that this object may be null, in which case the painting operation will usually be skipped.
