[Paraview] Desktop-delivery and LOD settings: no influence?

[Paul Melis]

Hi,

I'm doing remote rendering with PV 3.14.0, with quite a large set (isosurface of 98M tris) on 16 render nodes, each with a GTX460 and 12 GB RAM (Linux 64-bit cluster btw).

This model renders like a dog when interacting. I've checked the subsampling settings, compression settings and LOD settings to see make sure I'm actually using lower resolution rendering and model decimation during interaction. I have enabled LOD Threshold and set the value to 0 (to force LOD usage during interaction, per tooltip).

But I don't see any difference in the actual decimated model used during interactive rendering for different LOD Resolution values (checked using surface-with-edges repr and rendering without subsampling). I also don't see how the value for LOD resolution relates to the actual model used. I would expect something like quadric clustering to be used, but when e.g. setting LOD resolution to 10x10x10 the model during interaction uses many more triangles than "10 per direction" (or per data piece assigned per process, when showing Process Id Scalars).

I just don't see any difference between different LOD resolution settings. Am I missing a setting somewhere?

Regards,
Paul
