Class GViewport

Object
  GViewport

public class GViewport

extends Object

This class represent the area of the window where graphics will be drawn. The viewport is defined by three points as follows:

     x0,y0 o-------o  x1,y1
           |
           |
           |
     x2,y2 o
 

A typical viewport will have y0 == y1 and x2 == x0, but the definition makes it possible to create skewed viewports in order to produce pseudo 3D graphics for instance.

Clients sets viewport on a scene through the GScene.setViewport() methods.
