Hi All,<div><br></div><div>Is it possible to define a mask for a vtkImageStack so that every slice in the stack will appear transparent outside the mask?</div><div><br></div><div>Seems like it is only possible to "occlude" some parts of a slice by overlaying another slice that contains the mask. But the masked areas are still opaque.</div>
<div><br></div><div>I understand that for the masking technique I'm suggesting to work, I would need to be able to use some kind of multi-pass technique in order to mask the images in a temporary color buffer before writing to the main framebuffer. Is there any way to do that with vtk?</div>
<div><br></div><div>s.</div>
