Abstract
A system and method to accurately simulate digitally the rendering of a printed articulation, stroke, or mark of a donor natural medium used in graphic arts, such paints, pencils, erasers, or other implements. Using a computer (1) or other hardware the system and method of the invention allows a digital representation of dye-concentration color mixing, receptor grain and variable grain penetration, and a smooth and continuous brush stroke without visible artifacts. Other objects of the system and method of this invention include methods for varying the shape of the tip of an implement across the stroke for the purpose of accurately simulating brushes and other donor-receptor articulations common to natural media, and for rendering a brush stroke in multiple strokes to accurately simulate digitally brush bristles.
