Virtual faceted hard media imaging

Abstract

A tilt sensitive virtual marking implement is used to render an impression on an electronic presentation device. Further, a bearing measurement and/or a barrel rotation measurement of the virtual marking implement may be made with respect to the surface. The barrel rotation, tilt, and/or bearing are then used to vary geometry of an impression profile associated with a faceted physical marking implement as well as an intensity of the rendering. A user may actively vary the impression profile while he or she produces strokes of the virtual marking implement across the surface without changing the faceted physical marking implement selection or switching to a different virtual marking implement so that a corresponding impression profile mimics an impression of a facet on the faceted physical marking implement.
