Hi,
i have a bigger case (20e6 points) - there i found the time from
clicking for e.g. rotation till showing the coarse view (LOD) is nearly
the same, however from the coarse view back to the detailed one pv 3.9.0
is about factor of 2-4 slower compared to pv 3.8.1.
My settings of the LOD are:
LOD Threshold (on), 0 MB
LOD Resolution (160x160x160)
Outline Threshold: 0 MCells
LockInteractive Render 0
Allow Rendering Interrupts: off
Output of Timer Log:
3.9.0:
Interactive Render, 3.79491 seconds
Interactive Render, 0.029547 seconds
Still Render, 7.85055 seconds
Still Render, 6.95442 seconds

Execute vtkPolyDataMapper id: 169, 1.7e-05 seconds
OpenGL Dev Render, 0.000572 seconds
OpenGL Dev Render, 1.7e-05 seconds
What are the changes between 3.9.0 and 3.8.1 regarding the LOD? Seems,
3.9.0 is not using OpenGL? I have used the same complier-settings for
both versions.
If checked the effect with smaller cases - there the effect is smaller.
Best regards,
Stefan
