ABSTRACT
In this manuscript, we describe a process that can be used to create still and/or animated portrait paintings to be shown in Expressive Art Exhibit. Our process consists of two stages: (1) Creation of control textures for a Barycentric shader by using color information gathered from photographs to provide realistic looking skin rendering; (2) Filtering and compositing the layers of images that are obtained by control textures, which correspond to effects such as diffuse, specular and ambient. To demonstrate proof-of-concept, we have created a few rigid body animations of painterly portraits under different lighting conditions.

Real-time painterly rendering for MR applications
GRAPHITE '04: Proceedings of the 2nd international conference on Computer graphics and interactive techniques in Australasia and South East AsiaIn this paper we describe a real-time system for AR/MR rendering applications in a painterly style. Impressionistic images are created using a large number of brush strokes, which are organized as 3d particles to achieve frame-to-frame coherence. ...
