Perfect Shape 1.0.0 was released today, providing the Ruby community with an open-source library of Pure Ruby Geometric Algorithms. The reason behind creating this library was that before, there were no comprehensive geometric algorithm libraries in Ruby that covered all the geometric shapes like rectangle, square, arc (open, chord, and pie), ellipse, circle, polygon, and paths containing lines, quadratic bézier curves, and cubic bezier curves. Most of them either lacked support for certain shapes like arc or lacked algorithms for checking point containment in every shape, including Cubic Bezier Curves. Thankfully, Perfect Shape addresses that issue completely for the Ruby community.
