@scheggia it’s the polygon count that’s important, not where the models come from, so making them in Blender would not help. On the other hand 1360 tris is not very many…

Suggestions:
- try setting Stage.quality to LOW
- if you can, switch from pv3d to away3d or away3dlite – this engine, in the fp10 version, is significantly faster

hi, i am projecting a game with at maximum 36 cones and 5*36 circles. if i use PV3D to buil the objects are about 36*5+5*6*36=1360 triangles and the game appears slow, too much slow! do you think that importing the 3d object with blender could be faster?

@MikeTheVike No, I haven’t. But I intend to go back to the Blender/PV3D topic later this month, so I will check that and maybe update this post. Thanks!

Have you tried using the newest version of Blender? I think they might have fixed it. I successfully exported a dae file and loaded it into Papervision.

@vitaLee These are the windows system environment variables.

On an XP machine you set them by right-clikcking the ‘My Computer’ icon, choosing the ‘Advanced’ tab and then ‘Environment variables’ at the bottom.

You will see 2 panels, one for user variables on the top, other for system variables on the bottom. I added the Python related variables to the system ones so that they are available for every user.

hi Bartek.
where are suppose to set these python paths you were talking about?

Thanks Bartek, that’s a great help! I’d managed to do it using the PV3D components, but this way seems to have more flexibility – eg for combining collada objects and PV primitives. Have you had any success exporting meshes with armature animations as colladas from Blender? Can’t get those to work either…
Can’t wait for Blender 2.46 by the way.

Cheers

In my code it goes something like this:

cola = new Collada(“model.dae”);
colaHolder = new DisplayObject3D();
colaHolder.addChild(cola);
scene.addChild(colaHolder);

and then I modify the colaHolder properties such as rotation, postion etc… Anyway, I updated the post with the source files (see above), so grab them and check them out!

That’s great – I’ve just managed to load up my first dae from Blender into papervision, but I can’t work out how to access the object for position, rotation etc…

Here’s my .as file –

package {

import flash.display.Sprite;
import flash.display.Stage;
import flash.events.Event;

import org.papervision3d.cameras.Camera3D;
import org.papervision3d.objects.DisplayObject3D;
import org.papervision3d.objects.Collada;
import org.papervision3d.scenes.MovieScene3D;

public class collCube extends Sprite
{

public var scene:MovieScene3D;
public var camera:Camera3D;
public var dae:Collada;
public var myobject:DisplayObject3D;

public function collCube() {
init();
}

private function init() {
//basic scene stuff
var container:Sprite = new Sprite();
container.x = 200;
container.y = 200;
addChild( container );

scene = new MovieScene3D(container);

camera = new Camera3D();
camera.z = -500;
camera.zoom = 5;

var dae = new Collada(“cube.dae”);
var myobject = new DisplayObject3D();

myobject.addChild(dae);
scene.addChild(myobject);

stage.addEventListener(Event.ENTER_FRAME, runtime);

}

private function runtime(e:Event):void {
//WHAT CODE DO I USE HERE?
//dae.Cube.rotationX += 5;
scene.renderCamera(camera);

}
}
}

Would love it if you could help me out – or even better – post the code from your example.

Cheers

Karl
