This paper presents a unified rasterization method to render parametric curves and patches. The algorithms are extremely simple and fast. No multiplication and division are required. The proposed method combines strong sides of parametric and nonparametric representation of curves and patch...

Visualization of large medical data sets requires advanced techniques in image processing and data reduction. Compound data sets, which consist of several types of data, necessitate special treatment for each component. A data set which consists of both volumetric data and geomet...

This work describes DynSys3D, a framework for testing and implementing visualization techniques in the area of three-dimensional dynamical systems. DynSys3D has been designed to meet requirements which allow a fast and modular investigation of dynamical systems. Such requirements are, e.g., exten...

In this paper, a 2D constraint-based drawing system which distinguishes between visible and auxiliary geometry is presented. The auxiliary geometry is fixed by the geometrical constraints and represents a framework on which the entities of the visible geometry are mapped. In continuation...

Spline surfaces are very popular for the modeling of free form surfaces. This is because they are very flexible, conceptually simple and the shape can be easily controlled by manipulating control points. However, for complex shapes one has to deal with an overwhelming&...
