Skin And Bones in Papervision3D

When I was exploring Papervision3D source folders, I have seen MD2.as , DAE.as , ... , Bones.as, Skin3D.as , and I was sure that will works fine instantanetly.

First I have tried to use MD2 formats but I've not yet succeeded to find an adequate exporter. So I have try with a 3D model made , rigged and skinned in my favorite 3D application.

My firsts try was wrong because I tried to import it as Collada. Just changed Collada by DAE resolved the problem.

Joints were automatically converted to Bones3D, and mesh to Skin3D.

I have been able to animate my mesh using all weights params painted in favourite 3D application. I did not yet try to use Limits constraints.

I have just a little trouble when animate, if I rotate several properties of the same Bones3D, It is really hard to come back to the initial position. But I think it is due to the gimbal lock.

So this little Bones and skin Demo shows what you could be able to make when using rigged mesh in Papervision3D.

@Ben I will make it asap, but not much time right now.

 
/* Use of Papervision3d Bones */
/* Create a 3d Model with Maya, add joints , export with freecollada , check the joint box ( or check all boxes to be sure )
Then .... */
 
var colladaDataLoader : URLLoader = new URLLoader();
colladaDataLoader.dataFormat = new URLLoaderDataFormat.TEXT ;
colladaDataLoader.load( new URLRequest ("my dae file") );
 
/*When loader complete loaded */
var riggedDae : DAE = new DAE (XML(colladaDataLoader.data) );
/* When Dae successfully build */
riggedDae.getChildByName("my bone name" , true).localRotationY += 15;
 
/*I hope it help , but no more code needed */
 

Have a nice day.
