The Geometric Tools Engine is a collection of source code for computing in the fields of mathematics, geometry, graphics, image analysis and physics. The engine is written in C++ 14 and supports high-performance computing using CPU multithreading and general purpose GPU programming (GPGPU). Portions of the code are described in various books as well as in PDF documents available at the Geometric Tools Website.
The Geometric Tools Engine is licensed under the Boost Software License 1.0.
The mathematics code is in a header-only library, GTMathematics. A mathematics library with GPU-based implementations is provided, GTMathematicsGPU. The CPU-based common graphics engine code is in its own library, GTGraphics. DirectX 11 wrappers are provided for graphics and applications, GTGraphicsDX11 and GTApplicationsDX11, on Microsoft Windows 10/11. OpenGL 4.5 wrappers are provided for graphics and applications, GTGraphicsGL45 and GTApplicationsGL45, on Microsoft Windows 10/11 and on Linux. A small number of files exist to use GLX and X-Windows on Linux.
On Microsoft Windows 10/11, the code is maintained using Microsoft Visual Studio 2019/2022 with Microsoft's compilers, LLVM clang-cl or with Intel C++ Compiler 2022.
On Ubuntu 20.04.1 LTS, the code is maintained using Visual Studio Code 1.49.2 and CMake 3.15.2, NVIDIA graphics drivers, OpenGL 4.5 and gcc 9.3.0,
On Fedora 35, the code is maintained using Visual Studio Code 1.49.2 and CMake 3.18.3, NVIDIA graphics drivers, OpenGL 4.5 and gcc 11.2.1.
The repository contains many sample applications to illustrate some features of the engine. Top-level solutions/makefiles exist to build everything in the repository. Please read the installation and release notes to understand what is expected of your development environment.
