[vtkusers] A question about Rendering

[fofo]

Hi!everyone!
	When I am trying to render a flat volume data, I met a strange phenomenon.That is: when the volume was rotated to some special position, part of the image will disappear, just like been sheltered by shadow.
	Can you tell me how to solve this problem and what it is caused by? Thank you very much!!!
