Abstract
A drawing-tool renderer provides real-time rendering of lines with the look of artistic line drawings. A tip of a drawing tool (e.g., pencil) can be modeled as a constellation of points representing locations on the surface (or within the volume) of the tip. For a given point on a line being rendered, the location of the point and corresponding tool-tip parameters are used to determine which points in the tool tip model touch which portions of the paper. The effect of pigment transfer on cell color is modeled realistically. Various parameters of the model can be tuned to achieve a desired balance between rendering speed and accuracy of the simulation.
