Embodiments of the invention provide techniques for generating displays of vector drawing elements that have the appearance of being hand drawn using traditional media materials, such as a pencil. Multiple pencil strokes to be rendered on top of each other and the structure of the simulated paper surface remains constant, generating a realistic appearance for multiple rendered pencil strokes. A variety of physical characteristics of pencils and paper surfaces may be specified, and a convincing appearance may be achieved by modeling these parameters in software, and speed may be realized by rendering the pencil effect using a shader program executed on graphics hardware. |
