The Plane is the simplest object you can create with Papervision3D.

But “simple” does not mean we don’t have a set of options to custom our planes.

Look at this script, that is quite the same as the one published at Papervision3D for the absolute beginners:

package　{
　import　flash.display.Sprite;
　import　flash.events.Event;
　import　org.papervision3d.cameras.Camera3D;
　import　org.papervision3d.render.BasicRenderEngine;
　import　org.papervision3d.scenes.Scene3D;
　import　org.papervision3d.view.Viewport3D;
　import　org.papervision3d.objects.primitives.Plane;
　public　class　papervision　extends　Sprite　{
　　public　var　viewport:Viewport3D　=　new　Viewport3D();
　　public　var　scene:Scene3D　=　new　Scene3D();
　　public　var　camera:Camera3D　=　new　Camera3D();
　　public　var　renderer:BasicRenderEngine　=　new　BasicRenderEngine();
　　public　var　plane:Plane　=　new　Plane();
　　public　function　papervision()　{
　　　addChild(viewport);
　　　scene.addChild(plane);
　　　addEventListener(Event.ENTER_FRAME,　render);
　　}
　　public　function　render(e:Event)　{
　　　plane.pitch(1);
　　　renderer.renderScene(scene,　camera,　viewport);
　　}
　}
}

The only changes are I added an ENTER_FRAME listener to render the scene at every frame because renderScene renders the scene only once, and I added a pitch method to the plane to make it rotate along its x axis by 1 degree at every frame.
