Virtual endoscopy is a promising medical application of volume visualization techniques.
A virtual endoscopy system requires high quality and perspective projection rendering, as well as real-time navigation. This structure represents an approximation of the real organ. The cylindrical structure will be used to accelerate high quality volume rendering. Sketch representation of a 2D cut of an organ. It shows the wall and the cavity of the organ together with a possible wall interval definition.
