Hi,<br>
<br>
i found a rendering problem with cuts through polyhedral cells
depending on which rendering backend is used. For example in PV
5.1.2 compiled with<br>
<br>
VTK_RENDERING_BACKEND = OpenGL<br>
<br>
a cut looks like error.opengl.v5_1_2.png - there is a wrong shading
and some facets coming from the wrong starting point.<br>
<br>
Switching to OpenGL2 everything is fine (error.opengl2.v5_1_2.png).
This problem is the same with ParaView 5.2.0RC1 and OpenGL or
OpenGL2 - however there seems to be an additional (smaller) problem
using OpenGL2: there are some lines drawn outside of the shell - see
error.opengl2.v5_2_0rc1.png (cutted on a different position).<br>
<br>
The example cell is for testing is attached as "error.vtk" - cut
e.g. in x-direction on different positions to get the described
effects.<br>
<br>
Best regards,<br>
<br>
