# Geometric Primitives: Exact Orientation and Incircle Predicates using simd

This playground illustrates basic use of the the `simd_orient` and

`simd_incircle` predicates from the `simd` module, and compares them with

some other common methods of performing similar calculations.  Use this

sample code if you want to learn how to use these primitives correctly and

effectively.
