Creating a basic class for Papervision3D

In the previous sections you've learned what a basic scene is made of, and how you can create your own classes. Now that we have gone through all this theory, it's now time that we get our hands dirty by writing some code.

Start your favorite authoring tool. The first application we'll build is a 3D scene containing a sphere that is rotating over its y-axis. A sphere is basically a "3D ball" and is built into Papervision3D as one of the default primitives.

The basic document class

First, have a look at the document class that defines the basic structure for the rotating sphere application.

package {
import flash.display.Sprite;
import org.papervision3d.cameras.Camera3D;
import org.papervision3d.objects.primitives.Sphere;
import org.papervision3d.render.BasicRenderEngine;
import org.papervision3d.scenes.Scene3D;
import org.papervision3d.view.Viewport3D;
public class FirstApplication extends Sprite
{
private var scene:Scene3D;
private var viewport...
