Papervision 3D Cube Example

View Example

The goal for this example was to create a simple way to display a cube, then rotate it one side at a time. The image is just from Google Images which will be all 6 sides of the cube. This again like the exploding image example illustrates some control over your elements. You can easily modify this example to include mouse events that you can use trigger a view each side of the cube.
