[vtkusers] 3D rendering with Skin & colouring

[Gururajan]

Bill,

Thanks for your kind response, (try
actorskin.GetProperty().SetColor(1.0, .67, .67);)  thats right , but
this will help me in changing the skin colour,

but i need to form a layer like a skin which should cover the bone (like
human body).

Please guide me
Thanks
guru
