The Virtual Reality Modeling Language (VRML) is a new tool for the information transfer on the World Wide Web (WWW). We present a short description and some applications in the field of molecular graphics of this new, object oriented language. It is shown that the usage of VRML is a very efficient and powerful method for the transport of molecular models over the net.
A new concept in the field of molecular modeling using the information transfer mechanism of the World Wide Web (WWW) is presented. The Virtual Reality Modeling Language (VRML) provides an object-oriented method for the description of molecular models. The structure and capabilities of this new language are introduced. It is shown that the transport of molecular models over the WWW using VRML is a very efficient and powerful method for the exchange of molecular information.
The real-time texture mapping capabilities of modern graphics workstations are explored with respect to their applications in a variety of relevant scenarios in interactive molecular modeling techniques. The common usage of texture mapping to reduce geometric complexity while enhancing realism is extended, opening new ways to visualize large amounts of molecular data in a comprehensive fashion. Thus, texture mapping may be employed to (1) display and filter multichannel information of structural properties on molecular surfaces, (2) improve the quality and accuracy of highly complex isodensity contours, (3) increase the rendering speed of space-filling atomic representations by two orders of magnitude and (4) apply volume-rendering techniques to large, three-dimensional density distributions in real time. Implementation of these novel techniques requires only moderate modifications or extensions to existing molecular modeling applications.
