Methodology for Digital Compression of Virtual Worlds using VRML

Abstract

Virtual Reality Modelling Language called as VRML was an initial step in the direction of Web 3D. Second version of VRML called as VRML2 or VRML97 is an international Standard of 3D representation on Web with support for interactive behaviors. Web 3D is also sometimes referred as 3D on web. Web 3D allows user to browse 3D contents using Internet browsers like Internet Explorer, Mozilla Firefox, Opera, Google Chrome and so on.  Alternatively, there are many other alternative technologies of Web 3D similar to VRML but VRML is widely accepted format of import/export utility for many popular CAD software for exchange of CAD data.  Moreover, VRML code can be easily imported in software like MATLAB which gives more controls for further development. This paper proposes new methodology of constructing VRML worlds which enables extreme data compression suitable for virtual worlds constructed out of high polyline objects. With proposed new methodology, it is possible to develop mobile App with less than 10 MB size for VRML world. The proposed new methodology enables users to create interactive VRML worlds without any data or functionality loss. The proposed methodology helps in expanding scale and boundaries of Virtual Worlds which was limited to few 3D objects with Conventional Methodology. This paper discuss how VRML worlds can be endlessly expanded with space jump concept.
