Numerous visualization methods are used to model and render data of different modalities. In this paper, we present a new endoscopy system for virtual medicine. The main purpose of this system is to provide support for the planning of complicated endoscopic interventions inside of the ventricular system of the human brain. Although, our current focus is on ventricle endoscopy, this system is applicable to other areas as well. In order to achieve interactive framerates on workstations with medium graphics performance, we apply an efficient implementation of a basic algorithm for general visibility queries.10.2312/vissym19991024
