The need for courses on medical graphics, especially in real-time volume graphics, has increased. In order for students to develop skills sufficient to work on independent studies, or Bachelor's or Master's Theses, they will need 3 courses on computergraphics: course I teaches basic computergraphics according to the rendering pipeline;course II extends into advanced rendering and modeling algorithms and lays the foundation for computer-generated visualization;course III can then use these foundations to extend into medical graphics.
In this paper we present GPU-based techniques for the interactive visualization of large unsteady 3D flow fields on uniform grids. We propose a novel dual-core approach to asynchronously stream such fields from the CP...

A robust fitting and reconstruction algorithm has to cope with two major problems. First of all it has to be able to deal with noisy input data and outliers. Furthermore it should be capable of handling multiple data ...

Zoomable user interfaces are an evolutionary outgrowth of graphical user interfaces. In this paper we propose a zoomable user interface based on Scalable Vector graphics. Three-level zooming is proposed as a new paradigm to combine different zooming functionalities in a common interface and support zooming within the window manager. This helps to unify zooming techniques of different applications. To meet the demand of efficient and easy navigation on a user interface, several novel interaction techniques are shown that further support the integration of three-level zooming within the underlying presentation system. For mobile small-screen devices, where the benefit of zooming user interfaces is even higher, the proposed system can be operated with simple pen tap or tap and drag operations. We also present a prototypical implementation, which demonstrates how applications based on the SPARK toolkit can transparently benefit form the proposed technology.
In this paper, we present a new approach for automatic car detection from aerial images. The system exploits a robust machine learning method known as boosting for efficient car detection from high resolution aerial i...

Sketching communicates ideas rapidly through approximate visual images with low overhead (pencil and paper), no need for precision or specialized knowledge, and ease of low-level correction and revision. In contrast, most 3D computer modeling systems are good at generating arbitrary views of precise 3D models and support high-level editing andrevision. The SKETCH application described in this paper attempts to combine the advantages of each in order to create an environment for rapidly conceptualizing and editing approximate 3D scenes. To achieve this, SKETCH uses simple non-photorealistic rendering and a purely gestural interface based on simplified line drawings of primitives that allows all operations to be specified within the 3D world.
We describe a method for computing an implicit function that represents a surface by its zero level set, given a set of points scattered over the surface and associated with surface normal vectors. This implicit funct...
