SWF It Good

If you haven’t heard from the whole Flash community Papervision 3D 2.0 is out w/ textures, more interactive features and new coding conventions like BasicRenderEngine Class. I was working on a Coverflow thing for a client a week ago that I abandoned and just moded Doug McCune. But when I was going to do it myself I was using the Great White Trunk.

Here is what I came up with:

[as]

package
{

import caurina.transitions.Tweener;

import flash.display.*;
import flash.events.Event;

import org.papervision3d.cameras.*;
import org.papervision3d.materials.*;
import org.papervision3d.objects.*;
import org.papervision3d.objects.primitives.*;
import org.papervision3d.render.BasicRenderEngine;
import org.papervision3d.scenes.*;
import org.papervision3d.view.Viewport3D;;

public class PV3DTest extends Sprite
{
[Embed(source="images/one.jpg")]
private var Pic:Class;

public var scene:Scene3D;
public var camera:Camera3D;
public var viewport:Viewport3D;
public var renderer:BasicRenderEngine;
private var photoContainer:Plane;

public function PV3DTest()
{
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;
init();
}

private function init():void
{
scene = new Scene3D()
camera = new Camera3D();
camera.focus = 500;
camera.zoom = 3;

renderer = new BasicRenderEngine();

viewport = new Viewport3D(stage.stageWidth, stage.stageHeight, false, false, true, true);
viewport.addEventListener(Event.ADDED_TO_STAGE, init3d);
addChild(viewport);
}

private function init3d(e:Event = null):void
{
var data:Bitmap;
var photoMat:BitmapMaterial;

data = new Pic() as Bitmap;

photoMat = new BitmapMaterial(data.bitmapData);
photoContainer = new Plane(photoMat, 220, 210, 6, 6);
camera.target = photoContainer;
//photoContainer.yaw(45);

scene.addChild(photoContainer);
renderer.renderScene(scene, camera, viewport);
addEventListener(Event.ENTER_FRAME, render);
}

private function render(evt:Event):void
{
Tweener.addTween(photoContainer, {rotationY: 45, transition:”linear”, time:.5});
Tweener.addTween(viewport, {x: 300, transition:”linear”, time:.5});
renderer.renderScene(scene, camera, viewport);
}

}
}

Source | Example

I have been trying to understand Papervision 3d for the last couple of months, but all the examples are using collada or some elaborate functionality. I just wanted to test something simple. So I made a rotating box it rotates on the y axis.

Here how it goes in Flash CS3:

1. add an image into the library
2. set the linkage name to test.
3. make sure width = 336 / height = 335 (for this example)
4. and add this script

[as]

import org.papervision3d.objects.*;
import org.papervision3d.materials.*;
import org.papervision3d.scenes.*;
import org.papervision3d.cameras.*;

var container:Sprite = new Sprite();
container.x = stage.stageWidth * 0.5;
container.y = stage.stageHeight * 0.5;
addChild(container);

var scene:Scene3D = new Scene3D(container);
var camera:Camera3D = new Camera3D(p, 10);

var bam:BitmapAssetMaterial = new BitmapAssetMaterial(“test”)
bam.oneSide = false;
bam.smooth = true;

var p:Cube = new Cube(bam, 336, 335, 335, 5, 5, 5);

scene.addChild(p);

scene.renderCamera(camera);

addEventListener(Event.ENTER_FRAME, onFrame);

function onFrame(event:Event):void
{
p.rotationX % 360 == 0 ? p.rotationX = 1 : p.rotationX += 1;
trace(p.rotationX)
//p.rotationY = stage.mouseY – (stage.stageHeight * 0.5);

scene.renderCamera(camera);
}

[/as]

thats it
