## What it is
The Geometric Tools Engine (GTE) is a C++14 collection of source code for computing in mathematics, geometry, graphics, image analysis, and physics. It includes a header-only mathematics library, GPU-based math implementations, and DirectX 11 / OpenGL 4.6 graphics wrappers with many sample applications.

## Use cases
- compute geometric algorithms like distance, intersection, and mesh processing in C++
- build graphics applications with a CPU/GPU math and rendering engine
- use a header-only C++ mathematics library for high-performance computing
- run GPGPU implementations of math routines on NVIDIA GPUs
- analyze images with computational geometry and image analysis code
- prototype physics and geometry computations with sample applications

## When to choose
- you need robust, well-documented computational geometry and math routines in C++
- you want a graphics engine with both DirectX 11 and OpenGL 4.6 backends
- you need CPU multithreading or GPU-based math for high-performance computing
- you are working on Windows 10/11 or Linux with Visual Studio, CMake, and gcc toolchains

## When to avoid
- you need a lightweight, single-purpose library rather than a large engine collection
- your project targets platforms other than Windows or Linux (e.g., macOS or mobile)
- you want a managed or interpreted-language library instead of C++14
- you need turnkey application features rather than math/graphics building blocks

## Facets
