The applet above is a deferred software renderer in pure java.

The controls:

• Click on the applet to switch between point light and rotation mode.
• Drag with the right mouse button (or apple key on the mac) pressed to rotate the camera
• Drag with the middle mouse button (or alt key on the mac) pressed to translate the camera focus point
• Use the scroll wheel to zoom in and out

It features:

• Environment and spot lighting
• Normal mapping
• Ambient occlusion
• Per pixel material properties (including specular power and fresnel reflection)

To achieve material properties with environmental lighting, multiple environment maps are used. These were preprocessed with the very handy HDRShop
