ABSTRACT:
A computer based system for brush writing (calligraphy) employs a stylus operable on a working surface in a brush imitating manner. A digital processor receives signals indicative of stylus strokes during operation of the stylus, and establishes, in real time, images of brushed strokes. The images of brushed strokes correspond to the brush imiating operation of the stylus and are displayed in real time or printed at a desired later time. Geometric characteristics of the images of brushed strokes vary as a function of detected parameters of stylus operation. The function is user definable through a graph screen view. A teardrop shaped drawing primitive which changes as a function of stylus operation provides images of brushed strokes of Eastern calligraphy. A line primitive which changes as a function of stylus operation provides images of brushed strokes of Western calligraphy.
