Volume rendering techniques for medical applications face a number of problems that restrict the applicable techniques to a handful of established algorithms. Developing a virtual endoscopy application further narrows the choice due to the very specific demands of such a system. First, being able to move the viewpoint into the dataset and providing correct renderings incorporating the wide field of view optical endoscopy cameras usually deliver is a challenging task at a time when many of the available professional solutions like TeraRecon’s VolumePro boards are still restricted to orthogonal rendering. Second, the extreme perspective distortion of the image leads to an amplification of visible sampling artefacts, making it necessary to employ special techniques to deal with this problem. Third, highly interactive framerates are not a welcomed feature but an absolute necessity, since the possible intra-operative environment makes immediate response to certain actions essential. And last, correct visualization and intersection of the endoscopic tools have to be ensured in order to provide the surgeon with an adequate

Recently, the classic rendering pipeline in 3D graphics hardware has become flexible by means of programmable geometry engines and rasterization units. This development is primarily driven by the mass market of computer games and entertainment software, whose demand for new special effects and more

However, the current evolution of graphics hardware increasingly allows to combine the quality of off-line rendering approaches with highly interactive performance. In order to do so, new and customized algorithms have to be developed that take the specific structure

ABSTRACT Traditionally, virtual reality systems use 3D computer graphics to model and render virtual environments in real-time. This approach usually requires laborious modeling and expensive special purpose rendering hardware. The rendering quality and scene complexity are often limited because
