Creating Vector Scene Pictures on Cluster

rollmops94 · September 10, 2018, 05:34

Hi,

I am trying to create Pictures of a Vector Scene (Line Integral Convolution with velocity) on my cluster. I wrote a macro which creates picturs (hardcopies) from my simulation. I tested it on my local computer and then I tried it on the cluster. Everthing is working great (creating surface pressure pics, creating scalar scene sectioning pics,...), but the vector scene pictures aren´t created. The folder in which they should be is just empty and the macro isn´t running forward. It is like it stopps on the point in which the first hardcopy should be created.

Does anybody know what´s the problem?
(I have the same problem with the resampled volume pictures -> parts are in the pictures(the geometry of my parts), but the resampled volume which should be shown in scalar scene (Total Pressure) is not on the pictures - but lets first look at the problem with the vector pictures please)

Thank you!

It's my understanding that the Line Integral Convolution plots need what a graphics card provides. Mesa isn't good enough.

Thank you for your reply.

Do you know if there is any possibility to still create the LIC pics? Maybe with a smaller resolution?

No, you need graphics hardware for images like those. It's too hard to use software rendering.

It is possible to use the client-server feature to run the job on a cluster and have it render images on another node with a GPU.
