Method Detail

setScene

public void setScene(WPVSScene scene)

Parameters:

scene - the Scene to render

renderScene

public java.awt.image.BufferedImage renderScene()

Renders the scene to a BufferedImage. This Method uses the viewmatrix of the the ViewPoint class, which the defines the necessary viewing rotations and translations for the j3d scene.

Returns:

a BufferedImage where the scene has been rendered to

getImage

protected java.awt.image.RenderedImage getImage(javax.media.j3d.Canvas3D offScreenCanvas3D)

Called to render the scene into the offscreen Canvas3D

Parameters:

offScreenCanvas3D - to be rendered into

Returns:

a buffered image as a result of the Rendering.
