Weird artifacts in ParaFoam
Hi guys,
I've recently been seeing these weird artifacts when post-processing using ParaFoam when viewing slices: http://img267.imageshack.us/img267/2...dartifacts.jpg I have not seen anything like this before in OF1.6, and haven't noticed this in OF1.7 until now (since I haven't been using the slice function before this). Any idea on how to fix this problem? Thanks. My system is OpenSUSE 11.3 with ATI graphic card, if that helps. John |
Well, after some investigation it appears that the ATI driver is at fault. The flow field rendered correctly when using mesa driver through SSH.

Hi John,
Well, you got lucky that you only got artifacts. Some people aren't so lucky and get complete crashes of their machines, because the OpenGL driver (from the closed source ATI/NVidia/Intel drivers) put its finger in the wrong bits of memory, or GPU instructions, in the graphics card. You can try downgrading your ATI drivers to a previous version or upgrading to the most recent version. The other possibility is that you have enabled the nifty and sweet hardware acceleration for desktop display; you may loose eye candy when working on the desktop, but then it might be less likely that some application will crash due to it.
