Problems with texture transparency and segfault using GPU module/device #588

Open player1537 opened 4 months ago

Hi again RenderKit team đź‘‹

I'm doing a project using OSPRay for our Intel Center of Excellence program. The core idea is to create a rendering service/web API for visualizing biodiversity and energy efficiency data at a city scale.

We're at the phase of our project now where we have enough data (geometry, textures, etc) that we need to use the OSPRay GPU module/device.

During my testing, I noticed some weird rendering artifacts:

Initial symptom of the problem ![285ed794](https://github.com/RenderKit/ospray/assets/1215969/22bc5025-feee-4ae1-9ac1-1f60c1285cea)

Since then, I've tried to create a minimal reproducible example, and I've broken our problem down into a problem with textures. There are two symptoms:

First, on GPU, my texture maps are partly-to-mostly transparent. The amount and location of transparency is related to the texture size. In general, for a texture of size N, the first 1/N is only partially transparent and the remaining texture is varying degrees of mostly transparent.

Second, on GPU, copying the data for a 19x19 texture crashes OSPRay with a segfault inside a memcpy, inside ospray::Data::copy().

I did something kind of weird: my script to reproduce this problem is in Python using a ctypes-based wrapper around OSPRay. Everything works perfectly fine using the CPU device, so I don't believe the problem is related to my wrapper.

The source code for the script is in https://github.com/player1537-playground/OSPRay-GPU-Texture-Problem in the test.py file.

test.py has a small amount of documentation at the top, but the short form is:

2) Run the test.py script.

2a) Inside the script is a config variable, you can change it to change which test case to run.

2b) If the script is successful, it will create an image.png at the root of the repository.

Hi Tanner, nice to "see" you again :-)

  1. The initial image looks familiar. We fixed several issues related to textures on PVC in devel (soon v3.2), see e.g. 3692dd553e8181ca8c or 26de7347faa0dc6.
  2. I could not reproduce the crash with config=gpu19, but I was using the DPCPP-compiled v3.1 (not oneAPI). I also tried devel, which gives yet another result (see below), so this needs further investigation. The crash looks like access beyond the src array, could it be related to how the python wrappers use ospCopyData?
v3.1 devel
image-3 1 image-3 2 dev

Cheers, Johannes

I'm happy to hear that several texture problems have been fixed! Hopefully that bodes well for the issue that I'm facing.

I'll have access to that Intel DevCloud machine again in a couple of weeks, so I'll be able to do some more testing then.

Once I get access again, what's the best way for me to test the newest versions? Should I plan to build OSPRay and friends myself, or is there a nightly-built artifact that you can share with me?
