Documentation
type Origin = (Double, Double) Source #
Rotational origin relative to polygon center. (0.5, 0.5) is center of polygon. Top right is (1,1) and bottom left is (0,0)
rotationalTrajectory :: Origin -> Trajectory Source #
Interpolation by rotating around an origin point.
Example:
playThenReverseA $ pauseAround 0.5 0.5 $ mkAnimation 3 $ \t -> withStrokeLineJoin JoinRound $ let src = scale 8 $ center $ latex "X" dst = scale 8 $ center $ latex "H" in morph linear{morphTrajectory=rotationalTrajectory (0.5,0.5)} src dst t
