git clone --recursive https://github.com/hietwll/Fumeng.git
Both Embree and OIDN are optional for Fumeng, but it's strongly recommended to use them. You can just download the pre-built packages from their websites, and extract the packages.
cd /path/to/fumeng
cmake -B build -DCMAKE_BUILD_TYPE=Release -DUSE_FLOAT=TRUE -DUSE_EMBREE=TRUE -DUSE_OIDN=TRUE -Dembree_DIR=/path/to/embree/lib/cmake/embree-x.x.x -DOpenImageDenoise_DIR=/path/to/oidn/lib/cmake/OpenImageDenoise-x.x.x
- -DUSE_FLOAT: use single precision if TRUE, use double precision if FALSE
- -Dembree_DIR: directory of embree cmake config file
