Other usage issues

i'm developing a qt application which should display large-scaled meshes (say 10.000.00 volume elements) and i'm using occ version 6.2. I just wonder whether
meshVS classes have some limitations on mesh size...

If you only need display 10K volume elements, I believe OCC should be no problem. We use it to do some casting project, the elements is around 200~300K. However, if you wish to display 1M, then maybe you need do some optimization as our experience.
You can consider Paraview if you only for visualization.

thanks for your reply. i can display meshes with 2-3M size without problem,
but in 10M display() function of AIS_InteractiveContext class does not respond.
