A C++ math library providing classes for 2D/3D/4D vectors, matrices, quaternions, dual numbers, and projective/rigid geometric algebra elements like lines, planes, motors, and flectors. It is designed for 3D graphics and game engine development, authored by Eric Lengyel.
Use cases
- 3d vector and matrix math for game engines
- quaternion rotations for 3d graphics
- geometric algebra operations like lines planes and motors
- rigid body transforms and motion operators
- 2d and 3d transform math in c++
When to choose
- you need high-performance 3D math primitives in C++ for graphics or game engines
- you want to work with rigid geometric algebra (motors, flectors, flat points)
- you need a lightweight MIT-licensed math library without heavy dependencies
When to avoid
- you need a general-purpose linear algebra library with arbitrary-size matrices or GPU support
- you work in a language other than C++
- you need SIMD-explicit or GPU-accelerated math kernels out of the box
