Hi,I have an 3d image which is a brain and the air surrounding it when scanned, when I render the data on the window, it gives me a red cube, which should be the air, and I cannot see the brain, how can I tell vtk not to render the air voxels and show only the brain voxels? I guess one way to do it using thresholding, but I am not quite sure, please help.thankshank
