Artistic graphics and modeling
Elaine Cohen, Matthew Kaplan · 2007
Art is ubiquitous in our society. Indeed, its origins trace back to the birth of human society; primitive cave paintings have been discovered dating to 35,000 BC. People are taught from a very early age to think artistically. Drawing and painting are taught to almost every child. Therefore, it is only natural that humans have developed mechanisms, both biological and learned, for creating and interpreting works of art. It has been shown that typical viewers interpret art differently than photorealism in many instances. Therefore, rather than rely solely on photorealism, it is possible to coopt the viewer's innate capacity for artistic communication in order to communicate information in a different and, for some purposes, more effective manner. Additionally, because people are trained (albeit very often at a simple level) to create art, researchers may be able to use this training to develop alternative methods of user input that rely on some assumption of artistic ability. Towards these ends, we present a set of techniques that artistically model and render objects and scenes. First, we explore a variety of methods for rendering scenes artistically. To start, we present a system for interactive artistic rendering. This work creates a unified framework for rendering a variety of artistic effects with interframe coherency at interactive rates. Second, we present a system for stylizing renderings. We believe stylizations should be the product of deliberate user choices and that automatically creating artistic styles expands the creative and communicative vocabulary of an artist. We give a general definition of style and present a method for optimizing lighting configurations to create user-defined styles in renderings. Finally, we explore the use of art as a tool for interactive modeling. We present a technique that creates models based on hand drawn illustrations as input.
