<div>Hi vtkusers,</div> <div> </div> <div>I have a rectangular volume image which illustrates materials in a chunk of the earth. When the earth is flat, everything is OK. But when there is uneven topography, I do not know how to get rid of the air volume AND show a SMOOTH earth surface. The scalar of my volume image can be air/soil/rock density. This would be similar to show a volume image of human body or body part in the air with irregular body surface.</div> <div> </div> <div>FYI, my raw data is on an unstructured grid because of irregular shape of the earth. Someone please point me to the right direction about how to accomplish what I stated above.</div> <div> </div> <div>Thank you.</div> <div> </div> <div>Jim</div><p>
