The database, specifically geared for public school education, provides background information about the site s structures, excavation, dating, and function. Since Learning Sites' databases are independent of the virtual worlds at the program level, the content of the worlds can be tailored to suit the needs of specific constituencies, such as K-12 pupils, graduate students, scholars, or the general public. Eventually, our worlds will link to different scholars reconstructions of the site, different sites with related characteristics, and views of same site at different times as the settlement around it changed in size and character. The VRML 2.0 standard is making a significant difference to those who build 3D models within multimedia environments on systems both within the financial range of our target audiences and for the benefit of distance education. Now the full power of 3D environments can be combined with the full power of multimedia to create an unrivaled learning experience.
Objects can move, change, and react to the user.
Sound can provide ambient context and additional information through narration. VRML has changed all that, making possible the integration of VRML 3D data, standard HTML 2D text, pictures, and video in a World Wide Web page. Advanced features like frames and multiple windows permit simultaneous browsing of 3D and 2D information. Some Problems with VRML At its best, VRML permits the integration of 3D data into a multimedia environment. Unfortunately, the situation is not totally ideal.
