Abstract

A method of determining a tilt, bearing, and/or barrel rotation of a virtual marking implement with respect to a surface is disclosed herein. The tilt, bearing, and/or barrel rotation are used to vary geometry of an impression profile associated with a selected physical marking implement as well as the intensity of a rendering on an electronic presentation device. Further, the impression profile associated with the selected physical marking implement may change over time as marks are rendered on the electronic presentation device. More specifically, a quantity of use of the physical marking implement defines in part the size, orientation, and/or shape of one or more facets on the physical marking implement. Existing facets on the physical marking implement may be modified and/or new facets may be added to the physical marking implement as marks are rendered on the electronic presentation device.
