		<abstract>This paper describes an electronic paint system based on the canvas-ink-brushes paradigm. The system model is object-oriented and simulates some kinds of strokes using a hierarquical representation among the paint objects. The pigments used by the brushes have all the material properties interpreted as a texture which could be revealed by bump-mappings. The brushes can also be used to alter the height values of the canvas. This textured paint adds an extra physical dimension to the image and expands its expressive possibilities.</abstract>
