public class RMBezier extends RMQuadratic
This class models a simple bezier curve, providing methods for extracting points, distance calculation, bisection, hit detection and such.

  • Field Details

  • Constructor Details

    • RMBezier

      public RMBezier()
      Creates a new bezier.

    • RMBezier
