v0.36

SDF for a 2D star shape.

Parameters

• Radius: The distance from the center to each outer point on the star.
• Points: The number of points for the star. When this is a non-integer value there will be one point that is partially cut off at the bottom.
• Tightness: How much the inner points of the start are pulled towards the center. At zero this will produce a polygon with two sides for each point. At one it will produce thin lines radiating from the center.
• UV Mode:
  • None:
  • Cartesian:
  • Polar:
