Resumen
The article focuses on computer painting systems. Most technological advances in computer painting systems have focused on the appearance of the resulting images, less on capturing the interaction with the paint materials. The word "painterly" also describes a fusion of feeling, action, sight, touch, intent, and purpose beyond merely producing an image that gives an artistic impression. The dAb computer painting system uses a novel physically based, deformable 3D virtual brush to give the user intuitive control of complex brush strokes similar to that of real physical brushes. The graphical user interface provides a minimalistic set of keystrokes and simple control, along with a great deal of expressive power. The dAb paintbrushes deform in a natural physical way, as the user moves a virtual brush across the canvas. The user creates strokes with the brush, which behaves much as a real brush would. The dAb interactive painting experience provides direct interaction with the materials, as well as with the process of painting.
