OpenGL Mathematics
A header-only C++ mathematics library for graphics software based on the OpenGL Shading Language (GLSL) specifications.
What is OpenGL Mathematics?
GLM (OpenGL Mathematics) is a header-only C++ mathematics library specifically designed for graphics software. It provides GLSL-like vector, matrix, and quaternion operations, solving the need for a consistent and familiar math API in C++ graphics programming. It extends GLSL features with additional utilities for transformations, noise, and data packing.
Graphics programmers, game developers, and anyone writing C++ software that requires linear algebra for rendering, simulations, or image processing, especially those already familiar with GLSL.
Developers choose GLM for its strict GLSL compliance, which reduces cognitive load when switching between shader and application code. Its header-only design, lack of dependencies, and extensive feature set make it a lightweight yet powerful alternative to rolling custom math libraries.
