- Linux (Cent-OS 7), gcc10, C++14
- VTK-7.1 (various reason for not updating)
- No GPU available (running in VNC with OpenGL2)
- I also use Mesa3D (OpenSWR driver) but you can ignore at least for now because it’s probably irrelevant to my question and
vtkUnstructuredGrid to to
To my understanding by using vtkLODActor and setting the
vtkInteractor::SetDesiredUpdateRate() should adjust the various levels of detail in order to achieve that frame rate (i.e. the argument to the function e.g. 10 means 10fps).
Well, in my case
SetDesiredUpdateRate() seem to have no effect whatsoever.
Note that I deal with very large data sets (millions of points) that do not change (other than opacity and colors) where I end up with unaccepted rendering times of 1fps or less.
vtkRenderer::SetAllocatedRenderTime() does not seem to have any effect as well but how is is this related to
Thanks in advance
