Method Detail

addRenderable

public void addRenderable(LimnRenderable lr)

Description copied from interface: LimnRender

a renderable should be able to collect other objects that implement the Limnrednerable interface. These other objects are intented to provide additional augmentation graphics for the s

Specified by:

addRenderable in interface LimnRender

update

public void update(java.awt.Graphics g)

Overrides:

update in class java.awt.Component

prepImage

public void prepImage(LimnBasis l,
                      LimnRecorder r)

Description copied from interface: LimnRender

prepare/repaint the image for recording. This method will allow the canvas to repaint given the updated Basis and then notify the given recorder object that it has finished another image.

Specified by:
