Left: A vector painting made in our system exhibits both smooth gradients painted by soft brushes as well as infinitely sharp boundaries painted by hard brushes. Middle: The painting is represented by a planar triangle mesh. Right: Closeup showing the bottom of the letter B reveals both the sharp boundaries on the white region and a smooth gradient from blue to green in the background.
Abstract
Although vector graphics offer a number of benefits, conventional
vector painting programs offer only limited support for the
traditional painting metaphor. We propose a new algorithm that
translates a user’s mouse motion into a triangle mesh
representation. This triangle mesh can then be composited onto a
canvas containing an existing mesh representation of earlier
strokes. This representation allows the algorithm to render solid
colors and linear gradients. It also enables painting at any
resolution. This paradigm allows artists to create complex,
multi-scale drawings with gradients and sharp features while avoiding
pixel sampling artifacts.
