I have the following hardware:
HTC Vive Eye Pro
2*NVidia RTX 3090 GPUs
What I want to achieve: interactive ray tracing for a complex scene where the rays (e.g., primary rays) can be modified with respect to the gaze position.
Question: What is the best available API/ Engine/ Library to implement gaze-contingent ray tracing algorithm? Or for example, I extend to work on path tracing algorithm.
First I tried the unity3D, however, I have found the unity3d VR still support the directx11, and have not been updated to directx12, so ray tracing is not supported.
From the Unity discussion forum: RTX is not supported in VR in UE4 as of 4.26
There is a publication on RayVR, author used DirectX Raytracing-Falcor to enable ray tracing on VR (tr-05-2019.pdf (impa.br)), however the code repository is not available for public
Few publications, worked on VR and ray tracing used OpenCL RadeonRays
I would really appreciate if the experts show me a way that I should use to achieve my goal. I am really lost and randomly trying different path.
