For example, the following code:
onEnterFrame(ev:Event):void {
movableObject.mesh.geometry.subGeometries[0].updateVertexData(_points[_renderBuffer])
}
I got part of the code from the ShallowWaterDemo.as, however I do not know how they managed to have updateVertexData(...) run so fast: 30 FPS on ~80k polys.
Thanks.
