A new technique for interactive vector field visualization using large numbers of properly illuminated field lines is presented. Taking into account ambient, diffuse, and specular reflection terms as well as transparency and depth cueing, we employ a realistic shading model which significantly increases quality and realism of the resulting images. While many graphics workstations offer hardware...

Textures are essential to allow real-time rendering of computer graphics. While they are easy to use and widely supported by current graphic frameworks, their creation still involves a large amount of manual work. Within the recent years algorithms have been developed that help artists automating common tasks in texture creation. Those tasks can involve texture creation, manipulation and ®tting...

Visualizations of 2D scalar fields are often based on the rendering of 3D surfaces. Combinations of standard 3D rendering techniques using color, transparency, texturing, and lighting can be employed to create visualizations for multiple surfaces. However, the transition from foreground to background due to surface intersections can confound accurate surface perception, even for techniques that...

Autostereograms or SIRDS (Single Image Random-Dot Stereograms) are camou aged stereograms which combine the Julesz random-dot stereogram principle with the wallpaper e ect. They can represent any 3d shape on a single image having a quasiperiodic appearance. Rather large SIRDS can be interpreted in depth with unaided eyes. In the hands of computer graphic designers, SIRDS spread all over the wor...

In this paper we present an approach to optimize the workflow for a graphic artist currently working on high resolution photographs of architectural and archaeological monuments. These photographs are used as texture maps to color the meshes, which are calculated from laser-scanned point clouds corresponding to exactly those monuments. Because a particular region belonging to a monument is cove...

With the development of digital earth and cyber city, there is an increasing equipment on management and vitalization of integrated 3D model data and image data. How to improve the speed and visualization effect of three-dimesional (3D) model is a major research issue in 3D GIS. In order to improve the speed of 3D visualization, such as flying/walking through, many algorithms have been develope...
