Realistically representing our three-d international has been the topic of many (philosophical) discussions due to the fact precedent days. whereas the popularity of the globular form of the Earth is going again to Pythagoras’ statements of the 6th century B. C. , the two-dimensional, round depiction of the Earth’s floor has remained winning and in addition ruled the artwork of portray until eventually the overdue center a long time. Given the immature technological skill, gadgets at the Earth’s floor have been frequently represented in educational and technical disciplines by means of two-dimensional cross-sections orientated alongside mixtures of 3 at the same time perpendicular instructions. once machine technology developed, scientists have gradually been enhancing the third-dimensional illustration of the Earth and constructed innovations to investigate the various common techniques and phenomena participating on its floor. either desktop aided layout (CAD) and geographical details platforms (GIS) were built in parallel over the last 3 a long time. whereas the previous concentrates extra at the certain layout of geometric types of item shapes, the latter emphasizes the topological relationships among geographical items and research of spatial styles. still, this contrast has develop into more and more blurred and either techniques were built-in into advertisement software program programs. in recent times, an lively line of inquiry has emerged alongside the junctures of CAD and GIS, viz. 3D geoinformation technological know-how. experiences alongside this line have lately made major inroads by way of 3D modeling and information acquisition.

To the authors’ knowledge all the above described stereo-visualization methods have never before been applied to real and simulated – in our case historical – geodata. This premiere is meant to demonstrate different approaches of stereo-visualization for environmental purposes. Furthermore, True-3D Visualization of Glacier Retreat in the Dachstein Massif, Austria 31 the applied display techniques are supposed to give an impression of the great variety of 3D viewing hard- and softcopy methods. Due to the different media forms used, identical data bases can be presented to different user groups.

4) implements functionalities for image processing and rendering; thus, it requires more processing power. It is Java-based and can be integrated into a web page as a Java applet, which also allows for a broad range of applications. 48 B. Hagedorn et al. In addition to the color layer, this client also requests object id and depth layers. Object ids are used for selecting objects of the image. When an object is selected, the client highlights all the pixels that belong to this object and emphasizes its contour.

From virtual globes and online map systems users know to navigate by using mouse and keyboard in a real-time interactive manner. However, especial- Towards Advanced and Interactive Web Perspective View Services 45 ly due to the image-based approach, the WPVS inherently provides only non-real-time step-by-step navigation. , by sketching a desired point of interest. The portrayal service automatically interprets this navigation input, taking into account scene objects, their types, and their navigation affordances, and computes and responds a camera specification, which can be used for requesting the corresponding view.
