DVR issue with CAM/AdamPhillips

[sgpearse]

To reproduce:

1. Import the following as CF compliant data, on cisl-vapor:

/little_glade/data/Source/CAM/AdamPhillips/v5_rel04_BC5_ne120_t12_pop62/FV_768x1152.bilinear.v5_rel04_BC5_ne120_t12_pop62.cam.h0.0001-01.nc

2. Create and enable a DVR, and the following behavior can be seen:

Home viewpoint:

Rotate about the X axis:

@clyne comments:

That may simply be because the ROMS data are uber thin along the Z axis and are missed entirely by the sampling.

[sgpearse]

@shaomeng and @StasJ will try scaling it by a lot. Will also test on another machine.

If I really understand what "scaling it by a lot" means, I get the following.

I renders correctly for me:

Then ignore my previous comments about the data being too thin and not properly sampled. This looks like a GPU or driver-specific bug. Or, perhaps a regression introduced by #2813. @StasJ have you checked that? If it is a regression I think we either need to fix the current problem, or consider backing out #2813

Yes, it works correctly with the most recent version of the renderer.

@sgpearse can we close this after @StasJ backs out the changes for #2800?
