Even, I am looking a way to treat the loaded model (.obj) as rigidbody.

Basically, I am loading "PalmTrees.obj" and I've rolling ball. I want my ball to interact with these PlamTrees - ball should not cross over the tree.

Please help.

Finally, its done !!!

Here is the code to extract the mesh data from loaded model and apply rigidBody to it.

I used "TestPhysicsStaticMesh.as" class from Proscenium Samples folder to get this done.

//=======================================

_modelLoader = new OBJLoader( "../res/content/PalmTrees/PalmTrees.obj" );

_modelLoader.addEventListener( Event.COMPLETE, loadComplete);

protected function loadComplete( event:Event ):void

{

          var tree:SceneNode = new SceneNode( "PalmTrees" );

          var manifest:ModelManifest = _modelLoader.model.addTo( tree );

          var scale:Number = 2;

          for each (var boatMesh:SceneMesh in manifest.meshes)

          {

                    var indices:Vector.<uint> = new Vector.<uint>;

                    var vertices:Vector.<Number> = new Vector.<Number>;

                    var indexVertexArray:btTriangleIndexVertexArray;

                    var shape:btBvhTriangleMeshShape;

                    var boatCollision:SceneNode;

                    var rbody:btRigidBody;

                    boatMesh.getIndexVertexArrayCopyForAllElements( indices, vertices );

                    indexVertexArray = new btTriangleIndexVertexArray( indices.length/3, indices, vertices.length/3, vertices );

                    shape = new btBvhTriangleMeshShape(indexVertexArray,false);

                    boatCollision = new SceneNode;

                    boatMesh.addChild( boatCollision );

                    rbody = mPellet.createRigidBody(boatCollision, 0, shape);

                    shape.setLocalScaling(scale,scale,scale);

                    rbody.worldTransform.origin.setValue(10,0,-20);

                    boatCollision.physicsObject.collisionFlags |= btCollisionObject.CF_STATIC_OBJECT;

                    boatMesh.appendScale(scale,scale,scale);

                    boatMesh.appendTranslation(10,0,-20);

                    scene.addChild( boatMesh );

          }

}
