Virtual Presence Ltd, London-based virtual reality specialist that started out marketing products in the field imported from the US, has developed its own World Wide Web tool kit to create three-dimensional graphics. G Web is based on the recently-announced graphics standard Virtual Reality Modelling Language, VRML, a virtual reality equivalent of HyperText Mark-up Language, announced last month (CI No 2,639). The company says the product is an extension of Genesis, its virtual reality prototyping tool kit, launched last year. G Web has its own basic library of design tools but the company admits that in order to achieve advanced three-dimensional graphic images, users would need to use computer-aided design software and then import the files to G Web. The tool kit supports .DXF files and design software from 3D Studios Inc. Virtual Presence is targeting the product at two markets: out early next month, it will ship a Windows version needing a full 80486 with 8Mb memory for $250, for the creative home user, and a Silicon Graphics Inc workstation release, at $1,750, for firms seeing it as a new way of marketing products on the Web.
