DSVOL II - A distributed visualization and sonification application communicating via an XML-based protocol

Veridiana Christie Lucas SalvadorRosane MinghimHaim Levkowitz

Distribution of the visualization process over the World-Wide Web allows remote access to expensive resources, and the cooperation amongst teams of experts that are located in different places. This paper presents an architecture and a corresponding prototype implementation of a distributed system for visualization and sonification of scientific data. The distribution is accomplished by the addition of visualization and sonification servers, accessible over the Internet, and implemented using an XML-based SOAP (Simple Object Access Protocol) protocol. The system is an evolution of a previously-developed prototype, with improvement in the visualization and in the distribution aspects of the architecture. Former distribution schemes used CORBA (Common Object Request Broker). A comparison of both distribution tools is given in the light of visualization tasks.
