Untried (as of mid October 2020, though all the tests pass) Rust port of Jeremy Ong's SIMD-enabled plane-based geometric algebra library, "Klein". Most intrinsics code came via the C# version which had already gone through the C++ templates.
Run cargo run --example druid_3d_shapes in the demo directory to see an example drawn to a Druid window.
I'm uncertain about Rust conventions so please open Issues or contact me on bivector.net discord if something's unusual. This is a Rust learning project (as well as SIMD use and PGA itself)!
C++'s multiple constructors per class are replaced by default(), new( ... ) for an appropriate convenience constructor taking f32s as arguments, from( ... ) where constructing from a single object makes sense, and e.g. Motor::from_rotor_and_translator( ... ), Motor::from_screw_line(angle_rad: f32, dist: f32, l: Line) when construction from several objects at once makes sense.
Rust doesn't let you overload the function call operator, so if you want to e.g. apply a rotation please say let rotated = rotation.apply_to(something); instead.
The Point struct has extra methods scale and scaled (former mutates in place, latter returns new Point) which perform coordinate scaling.
The Mat4x4 struct has a perspective projection matrix constructor method.
