2.3 DUIM-Geometry Module
compose-transform-with-rotation
Generic function
Summary
Creates a new transform by composing a given rotation with a transform.
Signature
compose-transform-with-rotationtransform angle #key origin => transform
Arguments
- transform
- An instance of type
<transform>. - angle
- An instance of type
<real>. - origin
- An instance of type
<point>. Default value: (0,0).
Values
- transform
- An instance of type
<transform>.
Library
duim-geometry
Module
duim-geometry
Description
Creates a new transform by composing a given rotation with the transform transform. The order of composition is transform first, followed by the rotation transform.
The argument angle represents the angle by which to rotate, in radians.
The argument origin represents the point about which to rotate. The default is to rotate around (0,0).
Note that this function could be implemented by using make-rotation-transform and compose-transforms. It is provided because it is common to build up a transform as a series of simple transforms.
