Irregular3DSet Appearance attributes control

Dear all,

Please could you tell me how it is possible to modify locally the Appearance
attributes (line thickness, fill polygon/wireframe, ...)  of an
Irregular3DSet surface, if I have several of these surfaces displayed within
one DisplayImpl window.

Thanks in advance for your feadback.

Best regards, Dean.
