Detailed Description
The DeformableShape is an X3DShapeNode which makes it possible to deform the geometry of the shape when touching it with a haptics device.
The deformer field specifies an H3DCoordinateDeformerNode that determines how the coordinates should be deformed on contact. If NULL, no deformation will be done.
The geometry field must contain an X3DComposedGeometryNode, and the coordinates in its coord field are the ones that will be deformed.
The origCoord field contains the coordinates that the X3DComposedGeometryNode had when it was added to the X3DComposedGeometryNode. These are the coordinates that was used before any deformation started.
The deformedCoord field contains the coordinates after deformation of current contacts of haptics devices. These are the coordinates that will be used for graphics rendering.
The restingCoord fields contain the coordinates that the geometry will go back to when there are no contacts to the geometry any longer. If the deformation is non-plastic, this will be the same as origCoord.
