DEGREES

DEGREES

A string constant that's used to set the angleMode().

By default, functions such as rotate() and sin() expect angles measured in units of radians. Calling angleMode(DEGREES) ensures that angles are measured in units of degrees.

Note: TWO_PI radians equals 360˚.

Examples

DEGREES example 1

function setup()
  size(100, 100)

  background(200)

  -- Draw a red arc from 0 to HALF_PI radians.
  fill(255, 0, 0)
  arc(50, 50, 80, 80, 0, HALF_PI)

  -- Use degrees.
  angleMode(DEGREES)

  -- Draw a blue arc from 90˚ to 180˚.
  fill(0, 0, 255)
  arc(50, 50, 80, 80, 90, 180)

  describe('The bottom half of a circle drawn on a gray background. The bottom-right quarter is red. The bottom-left quarter is blue.')
