|
|
A linear algebra and mathematics library for computer graphics.
|
|
|
|
The library provides:
|
|
|
|
- vectors: `Vector2`, `Vector3`, `Vector4`
|
|
- square matrices: `Matrix2`, `Matrix3`, `Matrix4`
|
|
- a quaternion type: `Quaternion`
|
|
- rotation matrices: `Basis2`, `Basis3`
|
|
- angle units: `Rad`, `Deg`
|
|
- points: `Point2`, `Point3`
|
|
- perspective projections: `Perspective`, `PerspectiveFov`, `Ortho`
|
|
- spatial transformations: `AffineMatrix3`, `Transform3`
|
|
|
|
Not all of the functionality has been implemented yet, and the existing code
|
|
is not fully covered by the testsuite. If you encounter any mistakes or
|
|
omissions please let me know by posting an issue, or even better: send me a
|
|
pull request with a fix.
|
|
|
|
## Limitations
|
|
|
|
cgmath is _not_ an n-dimensional library and is aimed at computer graphics
|
|
applications rather than general linear algebra. It only offers the 2, 3, and
|
|
4 dimensional structures that are more than useful for most computer graphics
|
|
applications. This design decision was made in order to simplify the
|
|
implementation (Rust cannot paramerise over constants at compile time), and to
|
|
make dimension-specific optimisations easier in the future.

## Contributing
|
|
|
|
Pull requests are most welcome, especially in the realm of performance
|
|
enhancements and fixing any mistakes I may have made along the way. Unit tests
|
|
and benchmarks are also required, so help on that front would be most
|
|
appreciated.
