|
||||
MetaBrush is a GUI for brush calligraphy based on Bézier curves.
|
||||
|
||||
A brush stroke is defined by two components:
|
||||
|
||||
* the path of the brush, specified using quadratic Bézier curves,
|
||||
|
||||
* the shape of the brush, also specified with quadratic Bézier curves.
|
||||
|
||||
The shape of the brush is allowed to vary along the path.
