A basic linear algebra library for computer graphics. 🐶
Beagle is mostly inspired by GLSL (however Beagle is row-major) and attempts to recreate the majority of its functionality in Rust.
Beagle provides generic matrix and vector types up to 4x4 size. It provides all the operators you'd expect, including between vectors/matrices and scalars (though scalars must be wrapped with the v function).
Beagle also provides operations that function generically on both matrices and vectors (e.g component-wise comparisons, component-wise square roots, component summation).
Beagle makes it very easy to design your own custom component-wise functions.
Beagle also provides swizzles via the Index operator.
nightly, why?Sadly yes, for right now nightly is required. The things used are:
* associated_consts
* advanced_slice_patterns
I'd be willing to give up associated_consts, but advanced_slice_patterns are needed, so in for a penny, in for a pound.
unsafe in there, Should I be concerned?Yes, please voice your concern on rust-lang/rust#37302 so I can remove most of the unsafe code.
After that, the next thing blocking unsafe removal is the lack of IndexGet/IndexAssign for swizzles. unsafe is used to get slightly around this for some cases, but it's a bit of a hack until rust-lang/rfcs#997 goes anywhere.
There are a few unsafe things that won't be going away, however.
* The fast inverse square root floating point hacking.
* Cast back and forth between &[T; 4] and &Vec4<T>.
