I have already tried two ways to do it, but neither of them succeed.</div><div><br></div><div style="color: rgb(55, 86, 35); font-family: Microsoft YaHei;">1. Using vtkPolyDataToImageStencil<br>I got the example run on my computer, but the speed was really slow, it took me several minutes to compute a 256 * 256 * 256 volume data. What is the problem? Should the process take so long ?<br> What's worse, some of my surface to voxeliz is not watertight, which means I cannot use this route at all.</div><div><br></div><div style="color: rgb(55, 86, 35); font-family: Microsoft YaHei;">2. Then I found this mail in our mail list :<br><a href="http://public.kitware.com/pipermail/vtkusers/2002-April/011020.html" target="_parent">http://public.kitware.com/pipermail/vtkusers/2002-April/011020.html</a><br>I think rendering the mesh is a good idea, but I can only get 2D data , ie , a screen shot of the window. Is there anyway to obtain 3D data of the window , or should I move the camera to show the cross section of the mesh and screen shot the window again and again ?<br>In the bottom of the above mail , David said that I can also use vtkCutter to get section of the volume data , which is faster ?</div><div><br></div><div style="color: rgb(55, 86, 35); font-family: Microsoft YaHei;">Perhaps this is an small problem for advanced users, but it is driving me crazy, please help me !</div><div><br></div><div style="color: rgb(55, 86, 35); font-family: Microsoft YaHei;">Wei Ran, metorm at outlook.com </div><div style="color: rgb(55, 86, 35); font-family: Microsoft YaHei; font-size: 16px;"><br></div><div style="color: rgb(55, 86, 35); font-family: Microsoft YaHei; font-size: 16px;">Wei Ran, <a href="mailto:metorm@outlook.com" target="_parent">metorm at outlook.com</a> </div><div style="color: rgb(55, 86, 35); font-family: Microsoft YaHei; font-size: 16px;"><br></div><div style="color: rgb(55, 86, 35); font-family: Microsoft YaHei; font-size: 16px;"><br></div></div>
