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.

The whole concept for this project was inspired by a Japanese animation called, ‘Castle in the sky’. The starting credits to this film were animated with traditional pen and ink images. Being hand drawn this short introduction would have taken many weeks to complete, so from this it was questioned whether you could produce the same effect using Computer Graphics, therefore drastically shortening the time period of the process. The goal of my research is to provide a pen and ink shader that can be used on a 3D modelled scene to render out hand drawn effect images. This would then be providing a non-artist user with the ability to create convincing traditional pen and ink animation.
