Architectural Windows - 4x4 Transform Matrices - Video 6

The example program in this series, Architectural Windows, uses 4x4 transform matrices to map the 2D points in the polyline rectangles input by the from the polylines' entity coordinate systems to 3D points in AutoCAD's World Coordinate system. Some people don't know about Transform Matrices, but they should! They are really useful, amazing constructs. They allow rotation of any object's points around any arbitrary axis through the object's origin point, AND ALSO TRANSLATES the object's origin to any point in space, all in one neat, tidy matrix calculation. No need to do the 3D rotation and translation calculations separately. Check it out! All autolisp files and drawing files used in this video are available at https://github.com/ivanstarr1/Archite...
