This is a C++ wrapper around the NVIDIA OptiX library. It needs the rtac_base package installed, a working installation of CUDA 10.2 or later and the OptiX SDK 7.0 or later.
If you haven't installed CUDA yet, follow instructions from here.
Download the OptiX SDK from NVIDIA developers website. (You will need a NVIDIA developer account). Find a version that matches your NVIDIA driver version and CUDA version (see rtac_base installation).
Keep in mind that the RTAC framework was solely tested on the optix-7.3.0 SDK. While there should not be further compatibility issue with newer OptiX version, fall back to 7.3.0 if there are some.
Launch the downloaded script. It should generate a directory named NVIDIA-OptiX-SDK-7.3.0-linux64-x86_64 with 3 subdirectories 'doc', 'include', and 'SDK'.
Add a persistent environment variable 'OPTIX_PATH' pointing to the NVIDIA-OptiX-SDK-7.3.0-linux64-x86_64 directory (for example with the following commands)
echo "export OPTIX_PATH=<path_to_optix>/NVIDIA-OptiX-SDK-7.3.0-linux64-x86_64" >> $HOME/.bashrc
source $HOME/.bashrc
The OPTIX_PATH variable is needed for CMake to find proper header files.
