oyk

OYK is ODE (Open Dynamics Engine) bindings for Rust yaw kinetics

ODE * https://github.com/nomissbowling/oyk/blob/master/img/oyk_512x100.png?raw=true

Now this crate is tested on ode-0.16.2 dll version.

ode.dll drawstuff.dll for x64 Windows binary compiled with -DdDOUBLE by mingw

(It may work with VC, or other platforms.)
