Segmentation fault when rendering

Open Zod-L opened this issue 2 years ago • 7 comments

Hi, I encountered a segmentation fault when trying to render the bunny.xml in src/optixRenderer/cbox. My environment is ubuntu 20.04, CUDA 10.2, optix 5.11.0. The error message is listed as follows: Input file name: /home/zod/OptixRenderer/src/optixRenderer/cbox/bunny.xml Output file name: /home/zod/OptixRenderer/src/optixRenderer/cbox/bunny.rgbe Material num: 5 Shape num: 8 Vertex num: 72 Camera Parameters: Camera Field of View: 60 Width: 512 Height: 512 FovAxis: x Target: 278 273 -799 Origin: 278 273 -800 Up: 0 1 0 Sample Count: 8192 Sampler: independent Sampler Count: 8192 No Environmental maps.

No output file is generated. I tried all examples in cbox, all encountering the same problem. Could you please help me with it?

That's very weird. I suggest trying different rendering modes, to render diffuse albedo and normal and see what's going on.

I have tried all other modes, all reporting the same segment fault problem.

I encountered a similar problem, changing CMAKE_BUILD_TYPE from Release to Debug can solve this without loss of speed. I have no idea of how this happens. I guess it is caused by the mismatch of cudadriver and deprecated OptiX6 library. I once had a Release build working fine, but got Segmentation fault error after I upgraded my nvidia driver from 470 to 510 and linux headers from 5.4 to 5.10. The error persists even though I downgraded them.

RTX3090 do not support cuda10
