rigid-transform?
Generic function
Summary
Returns #t if the transform transforms the coordinate system as a rigid object.
Signature
rigid-transform?transform => boolean
Arguments
- transform
- An instance of type
<transform>.
Values
- boolean
- An instance of type
<boolean>.
Library
duim-geometry
Module
duim-geometry
Description
Returns #t if the transform transforms the coordinate system as a rigid object, that is, as a combination of translations, rotations, and pure reflections. Otherwise, it returns #f.
Rigid transforms are the most general category of transforms that preserve magnitudes of all lengths and angles.
