Open Flash and create a new Flash File (Actionscript 3.0).

Select frame 1 in the timeline and open the Actions Panel (Window-Actions or F9).

Import the basic Papervision 3D Classes that set up a 3D scene and all the necessary constituent parts.

import org.papervision3d.cameras.Camera3D;
import org.papervision3d.render.BasicRenderEngine;
import org.papervision3d.scenes.Scene3D;
import org.papervision3d.view.Viewport3D;

Import the classes for creating primitive shapes.

import org.papervision3d.objects.primitives.*;

Import the classes that deal with materials (textures that cover a 3D model).

import org.papervision3d.materials.*;
import org.papervision3d.materials.special.*;
import org.papervision3d.materials.utils.*;
import org.papervision3d.core.proto.MaterialObject3D;

Import the classes for creating a point light (a light emanating from a single point).

import org.papervision3d.lights.PointLight3D;

Import the classes for dealing with shading. Papervision 3D offers different types of shading - you need only import the type you are going to use, but in this case we'll import all of them.

import org.papervision3d.materials.shadematerials.CellMaterial;
import org.papervision3d.materials.shadematerials.FlatShadeMaterial;
import org.papervision3d.materials.shadematerials.GouraudMaterial;
import org.papervision3d.materials.shadematerials.PhongMaterial;

Next, create instances of all the basic elements required for a 3D scene, and set up the stage.

var viewport:Viewport3D=new Viewport3D(stage.stageWidth,stage.stageHeight);
var scene:Scene3D = new Scene3D();
var camera:Camera3D = new Camera3D();
var renderer:BasicRenderEngine = new BasicRenderEngine();

stage.scaleMode="showAll";

Now that all the basic components have been set up we can proceed with creating the objects in the scene.
