[Paraview] volume rendering of vtkRectilinearGrid
Hello, Does Paraview or VTK support volume rendering of vtkRectilinearGrid? Thanks. Weiguang ___ ParaView mailing list ParaView@paraview.org http://www.paraview.org/mailman/listinfo/paraview
[Paraview] Report a bug
Can someone report this bug (below) to the development team on my behalf? Thanks. Description of the bug: While linking cameras of two views, and you check/uncheck "Camera Parallel Projection", you will see the other view doesn't change accordingly. By "linking cameras", it should mean 100% identical viewing behavior.

Re: [Paraview] number of points in the Information tab
A naive question: how can a cylinder with resolution=10 have 40 points?

Re: [Paraview] number of points in the Information tab
Thanks for the answer, Cory.

Uncheck the "Capping" property and your source will have 20 points as you probably expected (but no end caps). If the point duplicating weren't done, the cylinder would look funny at the ends. Try running the Clean filter on the cylinder to see what it would look like. This merges the duplicate points.

I run into the same problem on linux.

Aashish, you're right --- it is fixed in version 5.1.0. Thanks. Weiguang On 08/07/2016 10:42 AM, Aashish Chaudhary wrote: Hi Weiguang, Have you tried recent release of paraview / vtk?

[Paraview] bug in v4.1
Version: Paraview 4.1.0 64-bit on Windows Recipe to reproduce the bug: (1) Sources->Cone; (2) Change opacity by moving the slider. A window will pop up, and it keeps printing message: ERROR: In C:\DBD\pvs-x64\paraview\src\paraview\VTK\Rendering\OpenGL\vtkOpenGLRenderer.cxx, line 1068 vtkOpenGLRenderer (0B2CDC50): failed after RenderPeel 1 OpenGL errors detected 0 : (1282) Invalid operation whenever it refreshes the display, even though the opacity is effectively changed.
