A Procedural Approach to Non-Photorealistic Rendering of Pen and Ink Illustration from Three-Dimensional Models

This paper is concerned with the development of non photorealistic rendering in the form of pen-and-ink illustration. In particular, I will be presenting two methods of shader creation through the RenderMan process, a two-dimensional method that involves striping along the u and v directions of an object and a three-dimensional method that is based on solid texturing. Non-photorealistic rendering (NPR) is still a relatively new area in computer graphics but has developed a strong appreciation in recent years. In this report, related work in this field will be briefly addressed and then the development of my own techniques will be explained. Finally, an animated short will be created using the shader, intending to emulate the aesthetics of traditional Pen and Ink illustration in a digital medium.

An Experimental Investigation into Deriving Procedural Creation of Abstract Images form Photographs

This project constitutes an investigation into the possibilities of procedurally generating abstract compositions with the artistic styles of artists Roberto Matta, Wassily Kandinsky and J.M.W. Turner as a goal. All results are derived from an source image, which works as a seed from which patterns, variation and colour can be extracted and built upon. The investigation involves exploring concepts of computer vision and image processing, as well as my own artistic direction and development.
