Flow-based Ornamental Element Packing

Michael A. J. Sweeney Best Student Paper Award
FLOWPAK is a technique for drawing ornamental designs consisting
of placed instances of simple shapes. These shapes, which we call
elements, are selected from a small library of templates.
The elements are deformed to flow along a direction field
interpolated from user-supplied strokes, giving a sense of visual
flow to the final composition, and constrained to lie within a
Our implementation computes a vector
field based on user strokes, constructs streamlines that conform
to the vector field, and places an element over each streamline.
An iterative refinement process then shifts and stretches the elements to improve the composition.
