Constructor Detail

• Polygon

  Polygon(Array<Vec2> vertList)

  Constructor takes a supplied list of vertices and generates a convex hull around them.

  Parameters:

  vertList - Vertices of polygon to create.

• Polygon

  Polygon(Double width, Double height)

  Constructor to generate a rectangle.

  Parameters:

  width - Desired width of rectangle

  height - Desired height of rectangle

• Polygon
