Towards Advanced Visualisation Techniques in Case
1999
The complexity of information systems has resulted in more sophisticated CASE tools which integrate multifaceted design information using metamodeling and hypertext technologies. A designer can use this vast amount of tightly coupled information efficiently only if it is presented based on his needs and cognitive capabilities. In this paper we discuss how representations in CASE can be improved using advanced visualisation techniques.
„Die Photographie als Hülfsmittel mikroskopischer Forschung”? Joseph von Gerlach (1820-1896) und die frühen anatomischen Mikrophotographen
2005
The Erlangen anatomist Joseph von Gerlach was one of the first medical researchers who used microphotography for their scientific aims in basic tissue research. Already in 1863, Gerlach published a famous handbook on the methodology of the microphotographic technique, entitled Die Photographie als Hulfsmittel mikroskopischer Forschung. Here, he discussed the technological, practical and epistemological standards and constraints of the newly introduced visualisation technique of scientific photography. The efforts and setbacks of Gerlachs' innovative approaches shall be characterised in the present paper. Furthermore, some of the most important arguments put forward by some of his peers are …
Real and simulated endoscopy of neurosurgical approaches in an anatomical model
1997
Endoscopy simulation is a new visualisation technique which can be used to visualise patient anatomy as seen through endoscopes. In the following, we describe the application of simulated endoscopy to neurosurgical endoscopic approaches. We assess different aspects of virtual images and their influence on the final result, as judged by clinicians. One of these aspects is the projective geometry which is used to render the 3D images. Rendering using stereographic projection leads to more realistic endoscopic views than perspective projection.
