Description

Illustrations play a major role in the education process. Whether used to teach a surgical or radiologic procedure, to illustrate normal or aberrant anatomy, or to explain the functioning of a technical device, illustration significantly impacts learning. Although many specimen are readily available as volumetric data sets (e.g. through CT or MRI scans), particularly in medicine, illustrations are commonly produced manually as static images in a time-consuming process. Our goal is to create a fully dynamic three-dimensional illustration environment which directly operates on volume data. Single images have the aesthetic appeal of traditional illustrations, but can be interactively altered and explored. For this purpose, new non-photorealistic shading models are required which capture the wide variety of artistic styles and techniques.

Task

Your task will be the development of non-photorealistic shading models for the generation of illustration-like images from volumetric data. You will implement one (or several) plug-in modules for VolumeShop, our prototype system for interactive direct volume illustration. You will work in a creative environment and can contribute your own ideas, rather than only implementing an algorithm or technique from a paper.

Requirements

Basic knowledge in computer graphics and visualization, C++ programming, experience with OpenGL and vertex/fragment programs is advantageous
