# robust2d

Robust geometric predicates based on Jonathan Schewchuk's library https://www.cs.cmu.edu/~quake/robust.html Provides a simple ffi wrapper for the C library as well as some ergonomic Rust types and functions.

# Example

`let` `_` `=` `arithmetic``::``Library``::`init`(``)``;` `//` Must initialize some static constants for the robust arithmetic
`//` Circle center at (0.0, 1.0) r=1.0
`let` a `=` `Point``::`new`(``-``1.``0``,` `1.``0``)``;`
`let` b `=` `Point``::`new`(``1.``0``,` `1.``0``)``;`
`let` c `=` `Point``::`new`(``0.``0``,` `2.``0``)``;`
`//` Test point
`let` p2 `=` `Point``::`new`(``0.``1``,` `0.``5``)``;`
`println!``(``"``{:?}``"``,` p2`.``orient_to_circle``(``&`a`,` `&`b`,` `&`c`)``)``;` `//` "Inside"
