dAb - Interactive Haptic Painting with 3D Virtual Brushes; a practice Siggraph presentation by Vincent Scheib

reproducing the look of painting. This project explores the
benefits of recreating the "sight, touch, action and feeling"
of the artistic process itself.

The system, dAb, provides the user with the traditional tools
of a painter. This setting, conceptually equivalent to a real
world painting environment, allows anyone to control a virtual
brush as he or she would a real brush.

To achieve this, we have designed a physically-based, deformable,
3D brush model and bi-directional, two-layer, paint model. These
allow the user to produce complex brush strokes intuitively. The
haptic feedback enhances the sense of realism and provides tactile
cues that enable the user to better manipulate the paint brush.
