Hi everybody ! What happens if I call: IndexedGeometryArray . setValidVertexCount( newCount ) with "newCount" smaller than the specified indexCount which I set in the constructor ? Will then only "newCount" vertices be rendered ? How can I change the number of rendered vertices in an IndexedGeometryArray ? How do I update data in case of by reference ? Can someone give me an example of an implementation of GeometryUpdater ? Is it possible to share a single array of vertices by several Geometry objects by reference ? How can I update the data in this case ? Thank you in advance !
