WebCAME

Although being a general-purpose tool, the navigation facilities have been designed with virtual archaeology applications in mind, and the behaviour of visitors to a real archaeological site is reflected, but navigation impossible in reality (e.g., changing elevation above ground) is also provided.

The interaction of the customized parts and the core encoding/decoding libraries with standard components is illustrated in Figure [Fig: sysdiag.wmf]. When the user connects to a WebCAME enabled web server, WebCAME is invoked by the standard plugin mechanism of the browser. After the database connection parameters have been received from the web server, the connection to the CAME server is initiated by the CAME client. The final display presented to the user is created by the browser's HTML renderer, but being handled by WebCAME.

Object identification

A method has been developed that enables passing of object semantics through the process of encoding, transmission, and decoding. This information can be used on the client side to query additional data to a specific part of the view-dependent multiresolution mesh. Moreover, it allows a part of the mesh to be transformed (e.g., moved to a different location for better inspection) within the multiresolution framework. The time and memory overhead introduced to distinguish between objects is negligible.

Object identifiers can be linked with application-dependent features, such as the visualization of the level of confidence or of the time period during which an object existed.
