BCBezierPath is a simple library to learn Animations for different type of routes/curves.
Currently it includes the class that prepares the Bezier Path for a Spiral route. You can use it to animate the object along that path.
BCBezierPath creates a UIBezierPath object for an Archimedean spiral.
Inputs:
- The center point of the spiral. The spiral starts this far from the center.
- The amount that the spiral grows in one revolution.
- The angle, in radians, at which to start the inside of the spiral.
- The angle, in radians, at which to end the spiral. Every 2π radians equals 1 full turn.
- The distance, in radians, between each control point on the resulting Bézier path. A smaller theta step results in a smoother curve, but with more points, which could impact performance.
Output:
- A new path object with the specified spiral.
