OSPRay isosurfaces do not seem to work #2450

Open clyne opened 4 years ago

clyne commented 4 years ago

I'm unable to render an isosurface using OSPRay with any data I've tested. The application hangs indefinitely much like it does with the volume renderer for some data: #2449. Unlike the volume renderer there is no way to control the isosurface sampling rate.

To reproduce:

  1. Load Duku.nc
  2. Enable the isosurface renderer with OSPRay selected as the rendering algorithm

Correction. The ospray isosurface renderer seems to work fine with regular gridded data, but not a all for curvilinear or unstructured dat.

Note: isosurfaces are currently disabled until Intel fixes their bug.

We should retest this with the latest version of OSPRay

I have done some experimenting with OSPRay 2.8 and it seems to be working.

clyne commented 2 years ago

It's working, but the image isn't terribly satisfying; lots of holes suggesting the sampling is inadequate. See attached image and session file. Can this be fixed? Reopening.

No, unfortunately OSPRay does not provide any controls over the isosurface renderer. The volume renderer controls are nops.

We should revisit with the next release of OSPRay (2.9?)

@sgpearse will reverify - maybe test 2.10 if it's still broken.

sgpearse commented 1 year ago

The problem persists on Ospray 2.10, but there doesn't seem like there's a lot we can do about it.

We currently distribute ospray 2.11. Need to retest.

sgpearse commented 2 months ago

Might be fixed with upgrading to Anari?
