vivid v0.2.1 Vivid.Transform.Point

Standard transformations which can be applied to points without knowing the details of the geometry.

Used extensively by Transform, however you can use these functions as input to the Transformable protocol, should you require.

Summary

Rotate a point degrees around an origin point

Rotate a point radians around an origin point

Scale a point (ie move it) by multiplying it’s distance from the 0, 0 point by x_factor and y_factor

Scale a point (ie move it) by multiplying it’s distance from the origin point by x_factor and y_factor

Translate a point (ie move it) by adding x and y to it’s coordinates

degrees()

degrees() :: number

radians()

radians() :: number

rotate(point, origin, degrees)

rotate(Vivid.Point.t, Vivid.Point.t, degrees) :: Vivid.Point.t

Rotate a point degrees around an origin point.

rotate_radians(point1, point2, radians)

rotate_radians(Vivid.Point.t, Vivid.Point.t, radians) :: Vivid.Point.t

Rotate a point radians around an origin point.

scale(point, x_factor, y_factor)

scale(Vivid.Point, number, number) :: Vivid.Point.t

Scale a point (ie move it) by multiplying it’s distance from the 0, 0 point by x_factor and y_factor.

scale(point, x_factor, y_factor, origin)

Scale a point (ie move it) by multiplying it’s distance from the origin point by x_factor and y_factor.

translate(point, x, y)

translate(Vivid.Point.t, number, number) :: Vivid.Point.t

Translate a point (ie move it) by adding x and y to it’s coordinates.
