Overview

PhysRay SDK is a high performance modern graphics/compute SDK on OPLUS platform. It is mainly focusing on giving developers the ability to quickly utilize the latest graphics features provided by modern Android platform, such as real time ray tracing and heterogenous computing. Check out MANUAL.md for detailed explanation for the SDK features and tutorials of how to use them.

Please follow this document for detailed build instructions: BUILD.md

FAQ

Q: Does the SDK support OpenGL/ES

A: No. This SDK is based on Vulkan 1.1+ API.

Q: Does the SDK support ray tracing effect on mobile platform?

A: Yes. The new SDK will support Qualcomm Snapdragon 8Gen2, 8Gen3, and MTK D9200, DX-2, DX-3 platform.

Q: Is the ray tracing effect accelerated by hardware? What about on mobile platform?

A: The rendering is fully hardware accelerated on ray tracing capable hardware, such as NVIDIA GeForce 20XX graphics card. On mobile platform though, the rendering is currently simulated via regular shader (FS, CS) pipeline.
