Abstract

The presently disclosed technology teaches using a tilt-sensitive virtual marking implement to render an impression on an electronic presentation device. Further, a bearing measurement and a tilt measurement of the virtual marking implement are made with respect to the surface. The tilt and bearing are then used to vary geometry of an impression profile associated with the 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 physical marking implement selection or switching to a different virtual marking implement. When creating a rendering on a virtual canvas using the virtual marking implement and the surface, a user may wish to vary an orientation of the virtual marking implement so that a corresponding impression profile mimics an impression of a selected physical marking implement.
