vmath is a standalone vector math library for go, supporting both float32 and int types.
Matrices are stored in column major order.
This library provides 2D, 3D and 4D vector and matrix types with an extensive set of operations and utility functions.
Vectors are both provided for float32 and int.
Additional support for quaternions is also provided.
vmath aims to provide all functionality needed for graphics development (eg. using OpenGL) in a highly performant matter. It therefore also offers basic functionality related to spatial calculations.
Related functionality from the standard math package that go only provides for float64 is available for the float32 type in this package.
This library is inspired by glm, which is typically used by C or C++ projects.
Alternative go packages:
MathGL provides similar functionality for float32 and float64 types,
but does not support int.
Besides int vectors, this package is missing some features like geometric utility functions, float32 versions for functionality available in the math package,
and a few methods that you might or might not need.
Azul3D is a game engine written in go, that contains its own math functions in the sub-package github.com/azul3d/engine/lmath.
However, Azul3D uses float64 and is also missing some key features (like 2x2 matrices and int vector support).
Furthermore, the subpackage is not intended to be used as a standalone library and Azul3D is also no longer maintained.
Feel free to submit bug reports or pull requests for new features, examples or unit tests.
