==================================================================
Optix 7, CUDA 10, and a recent NVIDIA driver.
Mind this project uses a git submodule, so idealy clone with
--recursive flag:
git clone --recursive [email protected]:ingowald/rtxTetAdvect
If you did close without this flag, you can afterwards also do a
git submodule init
git submodule update
Building then via cmake and your favorite compiler toolchain.
For linux, I assume that nvcc is in the default path, and that there is environment variable names 'OptiX_INSTALL_DIR` that points to the optix SDK install directory
cd rtxTetAdvect
mkdir bin
cd bin
cmake ..
make
If you have any missing dependencies ccmake will tell you... just fix and re-run cmake
For windows, install Visual Studio (2017+), CUDA (10.1+) and Optix 7 first. Then run cmake-gui and click configure with following
paramters:
CUDA_HOST_COMPILER =
C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.26.28801/bin/Hostx64/x64/cl.exe
OptiX_INCLUDE =
C:/ProgramData/NVIDIA Corporation/OptiX SDK 7.0.0/include
