Abstract
A matrix multiplier is disclosed for rotating, scaling, shearing, and stretching, three-dimensional calligraphic images. This system has particular application to incremental vector generators. The transformations are performed in real time and at the drawing rate of the display device (CRT, plotter, etc.). Complex curved images are transformed as quickly as straight lines. This system reduces matrix multiplication to incremental additions distributed along each line of an image as it is drawn.
