Abstract:
Most non-photorealistic-rendering solutions tend to involve brilliant but unwieldy new technologies, such as volume-based rendering engines or complex image analysis. Similar results can often be achieved using simpler methods and non-proprietary toolsets, even toolsets designed with other effects in mind. Our studio has been experimenting with ways to achieve a hand-painted look with basic tools that are common to most 3D applications.
