Class movelight

java.lang.Object
  net.letskit.redbook.glskeleton
      net.letskit.redbook.first.movelight

All Implemented Interfaces:

java.awt.event.KeyListener, java.awt.event.MouseListener, java.util.EventListener, javax.media.opengl.GLEventListener

public class movelight
extends glskeleton
implements javax.media.opengl.GLEventListener, java.awt.event.KeyListener, java.awt.event.MouseListener

This program demonstrates when to issue lighting and transformation commands to render a model with a light which is moved by a modeling transformation (rotate or translate). The light position is reset after the modeling transformation is called. The eye position does not change.

A sphere is drawn using a grey material characteristic. A single light source illuminates the object.

Interaction: pressing the left or middle mouse button alters the modeling transformation (x rotation) by 30 degrees. The scene is then redrawn with the light in a new position.
