You can update geometry in live Shape3D nodes in one of two ways.
First, you can replace the Geometry object referred to by a Shape3D
node using the Shape3D.setGeometry (or .addGeometry) method. Second,
you can modify the vertices of an existing GeometryArray object either
using the setCoord*, setColor*, etc., methods (for by-copying geometry)
or by using the GeometryUpdater interface (for by-ref geometry). In
all cases, you must set the appropriate capability bits. This should
give you the flexibility that you need.
