1. Efficient real-time visibility testing
Abstract : Visibility testing is an integral part of many computer graphics algorithms. For example, algorithms that generate images with shadows, ambient occlusion, environment lighting or transparency all require an efficient means of establishing the visibility between two or more points in a virtual scene.

2. Real-Time GPU Techniques for Advanced Lighting Phenomena
Abstract : In the real world, the visual perception of an object is completely determined by the object's interactions with light. One large application of computer graphics is to visualize virtual objects and worlds in a fashion that is familiar to humans. Successfully emulating light and its effects on virtual objects therefore plays a central role. READ MORE

3. Efficient Methods for Volumetric Illumination
Abstract : Modern imaging modalities can generate three-dimensional datasets with a very high detail level. To transfer all the information to the user in an efficient way there is a need for three-dimensional visualization. READ MORE

4. A Real-Time Soft Shadow Volume Algorithm
Abstract : Rendering of shadows is a very important ingredient in three-dimensional graphics since they increase the level of realism and provide cues to spatial relationships. Area or volumetric light sources give rise to so called soft shadows, i.e., there is a smooth transition from no shadow to full shadow. READ MORE

5. Enhancing Salient Features in Volumetric Data Using Illumination and Transfer Functions
Abstract : The visualization of volume data is a fundamental component in the medical domain. Volume data is used in the clinical work-flow to diagnose patients and is therefore of uttermost importance. READ MORE
