HIP RT is a ray tracing library for HIP, making it easy to write ray-tracing applications in HIP. The APIs and library are designed to be minimal, lower level, and simple to use and integrate into any existing HIP applications.
Although there are other ray tracing APIs which introduce many new things, we designed HIP RT in a slightly different way so you do not need to learn many new kernel types.
Download the latest version – v2.2.0e68f54 (December 2023)
This release adds the following
- Multi-level instancing
- Triangle pairing
- AS Compaction
- Optimized BVH build speed
- Ray triangle intersection.
- Ray custom primitive intersection.
- Ray mask to filter geometries.
- Several bounding volume hierarchy (BVH) options.
- Load and store BVH handy for offline construction.
- BVH import.
- Motion blur.
HIP RT runs on AMD and NVIDIA® GPUs. HIP and CUDA® APIs are dynamically loaded so you do not need to have these SDKs if your have these dlls installed with the driver package. Hardware accelerated ray-tracing only works on RDNA™ 2 GPUs (Radeon™ RX 6000 series or newer).
The supported AMD GPU architecture families are:
- Navi3x (Radeon RX™ 7000 series).
- Navi2x (Radeon RX™ 6000 series).
- Navi1x (Radeon RX™ 5000 series).
You will also need AMD Software: Adrenalin Edition 23.30 or later for Windows and ROCm 5.7 for Linux.
