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
|
2014-01-27 05:11:20 +00:00
|
|
|
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
|
2013-09-17 09:02:28 +00:00
|
|
|
appreciated.
