[JAVA3D] adding vertex to existing Geometry

[hterrolle]

Hi,   I would like to add vertex to already exiting geometry. I thought doing it inside my Behavior trough the Updatedata of the GeometryUpdeter. But i do not know if it is possible. Because that i read from GeometryArray method allow to modified existing vertex but not to add new one to the geometry.   So it is possible to add new vertex to existing geometry and if it is could you help me to find my way   Thanks         herve
