[Paraview] [EXTERNAL] Opacity crashing ParaView and Value Range field for creating multiple slices is missing

[Scott, W Alan]

Mary,
Since one computer works and the other doesn’t, sounds like a graphics card issue to me.  Try updating your graphics drivers?  Also, try PV 4.3.0.  I know there was a problem with some volume rendering for older versions of OpenGL.  This should be fixed for PV 4.3.0.  Note that the next version of ParaView will require a somewhat newer version of OpenGL than PV 4.3.0, so if this is the problem, you are on borrowed time for volume rendering and opacity rendering.

I just tried, and got multiple slices to work just fine.  The trick is to click on the blue plus sign, slightly right of the Value Range window.  You can then edit the value that appears.  Does that work?

Alan

Subject: [EXTERNAL] [Paraview] Opacity crashing ParaView and Value Range field for creating multiple slices is missing

Hi,

I'm new to ParaView and going through the first webinar, using the demo data set disk_out.ref. I'm using ParaView 4.2.0 on two different Windows 64-bit computers.

I'm having two problems, one on each computer.

1. On the first computer, a desktop, when I go to change opacity of the main disk_out_ref.ex2 object, ParaView crashes. Is this a problem with my graphics card?

2. On the second computer, a laptop, the opacity changes just fine, however, for creating multiple slices, the Value Range field is missing (under the Properties tab for Slice 1, immediately under the "Triangulate the slice" option). How do I get it to show up? I have tried quitting and restarting, and also tried ParaView 4.3.0 and had no success.

Thanks,

- Mary
