Getting at individual pixels...

843799

After and individual frame has been rendered, i'd like to get at the individual pixels and alter them before the frame is displayed. By overriding the canvas3d's postRender() method, i can add my own code into the rendering loop, but does anyone know how i can get the individual RGB values of the frames pixels to alter them?

How do you override the canvas' postRender() method.

Please give me sample code.

Over-ride the existing canvas3d, and specify your own preRender method. Something like:

public class MyCanvas3D extends Canvas3D
{
public MyCanvas3D
{
super.Canvas3D()
}

public void preRender()
{

}

}
