Detray is part of the ACTS project (R&D line for parallelization), the ACTS project can be found: https://github.com/acts-project/acts.
This is a C++17 header only library for detector surface intersections using different algebra plugin libraries. It follows the navigation and propagation concept of ACTS, however, with an attempt to create a geometry without polymorphic inheritance structure.
- The C++ compiler must support C++17
- The CUDA Toolkit version must be greater than major version 11
- CMake
The respository is meant to be possible to build "out of the box", with standard CMake build procedures.
git clone https://github.com/acts-project/detray.git
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -S detray -B detray-build
cmake --build detray-buildFor tests and benchmarks with the inhomogeneous magnetic field, the ODD field in covfie format should be downloaded and the environment variable should be set.
