rtxTetAdvect - Collaboration Project for RTX-accelerated Tet-Mesh Particle Advection
==================================================================
Building
==================================================================
Dependencies
Optix 7, CUDA 10, and a recent NVIDIA driver.
Checkout w/ Submodule
Mind this project uses a git submodule, so idealy clone with
--recursive flag:
git clone --recursive http://github.com/owl-project/tetMeshQueries
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.
Building on Linux
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 tetMeshQueries
mkdir bin
cd bin
cmake ..
make
If you have any missing dependencies ccmake will tell you... just fix and re-run cmake
Building on Windows
- Install one-TBB.
- Modify
OptiX_INSTALL_DIRandTBB_ROOT_PATHin cmake. - Use CMake-GUI to build Visual Studio project, then use VS to build.
-
- Specifics: source code path is ...Gitlab/owl, binaries ...Gitlab/owl/build, and after pushing the Configure button choose x64 for the optional platform.
-
- If you get "OptiX headers (optix.h and friends) not found." then define OptiX_INCLUDE manually in CMake-gui by setting it to C:/ProgramData/NVIDIA Corporation/OptiX SDK 7.0.0/include
-
- You may need to Configure twice.

In addition, many of the core algorithms were imported from a project originally co-authored also by Will Usher and Nate Morrical, from the SCI Insitute, University of Utah.
