Bertwim, I'm not sure that the volume renderer can handle VTK_HEXAHEDRON elements. Try the Tetrahedralize filter on your source and see if the Volume representation works. Thanks, Cory On Mon, Oct 13, 2014 at 10:19 AM, B.W.H. van Beest b...@xs4all.nl wrote: Hi, I'm struggling to get a proper

No, it doesn't work. The filter creates tets, which are visible in the wireframe representation, but when I select Volume representation the image disappears. I can't imagine it is so difficult to render a volume in Paraview. I must be doing something wrong Regards, Bertwim On 10/13/2014

do you have any scalars? those are not optional for volume rendering. Additionally you may need to adjust the transfer function, On 10/13/2014 10:22 AM, B.W.H. van Beest wrote: No, it doesn't work. The filter creates tets, which are visible in the wireframe representation, but when I select

Yes, I do set a scalar for each cell. I left them out in the example, as also with a scalar I couldn't get a volume display. I'm not sure what you mean by adjusting the transfer function. Regards, Bertwim On 10/13/2014 07:28 PM, Burlen Loring wrote: do you have any scalars? those are not

Aashish, I do see errors in the wavelet example, but not in the other cases. If ok with you , I'll send the full code (it is not much, ~100K) as a zipped tar file by email. There is no other data. Regards, Bertwim On 10/13/2014 07:43 PM, Aashish Chaudhary wrote: Bertwim, If you are seeing

Cory, Bertwin, et al.; The exact volume of an arbitrarily oriented, arbitrary 8-vertex hexahedron can be computed with a very elementary construct. First, place an average-coordinate point at the center of the hexahedron; this point will be a common vertex point for a set of tetrahedrons

Samuel, Thanks for taking the efforts to dive into this. In fact, it is a good reminder to me to try a single tetraeder first. My primary problem seems to be that I cannot get volume rendering to work. Kind Regards, Bertwim On 10/13/2014 07:17 PM, Samuel Key wrote: Cory, Bertwin, et al.; The
