The hatching shape is our primitive for supporting hand-drawn hatching from imagination. A hatching shape comprises a mask and three rasterized fields—width, spacing, and direction. Streamline advection uses these fields to create hatching marks. A hatching shape also contains barrier curves: deliberate discontinuities useful for drawing complex forms. We explain several operations on hatching shapes, such as the multi-dir operation, an easy way to depict 3D form using a hatching shape’s direction field. We also explain the modifications to streamline advection necessary to handle barrier curves.
