Projective Transformation (aka: Homography, Collineation) is the technical term for the more familiar “perspective transformation”.


The Autodesk® AutoCAD® graphics sub-system does an excellent job for 3D geometry, but may be a bit cumbersome for 2D.


That situation may benefit from a more dedicated process. This routine will map 2D back and forth between orthographic and non-orthographic reference geometry.


Orthographic - 1Pt Perspective, Orthographic - 2Pt Perspective . . . . Or Orthographic - Skewed for Shear operations and Isometric Drawings . . . . Or, Orthographic - Orthographic for Non-Uniform Scale.


One other benefit is that curved geometry (circles, ellipses, splines) maintain %100 fidelity, i.e., no faceting.
