AkariRender is a CPU/GPU physically based renderer written in Rust and powered by LuisaCompute. Previous version with PPG and SMCMC is in legacy-cpp branch

Features

• Loading Blender scene
• Supports a subset of Cycles shader graph via JIT
• RGB/Spectral Rendering (WIP)
• Path Tracing
• Path Tracing with Metropolis Sampling
• Gradient Domain Path Tracing

Building:

If you are using < Windows 10, please upgrade to Windows 10 or above.

• CMake > 3.23
• Ninja
• Clone Blender 4.0 source code from blender-v4.0-release branch
• Put path to blender source in blender_src_path.txt
• Clone LuisaCompute alongside this repo

If you intend to run the renderer on cpu, the following runtime requirement must be satisfied:

• clang++ in PATH
• llvm dynamic library of the same version. For Windows users, it is the LLVM-C.dll.

Run

cargo run --release --bin akari-cli -- -d (cpu|cuda|dx|metal) -s scenes/cbox/scene.json -m scenes/cbox/test.json
