             Techniques of Perception in VRML97 
              by n_polys 08_2001 
            Quickstart: 3D Media and Web
              Technology
            With over 30 million PCs in the market that
              are already accellerated with 3D hardware, and more power shipping
              every month, real-time 3D media is cresting on a wave of viability
              as technology surges from narrow to broadband.  This presents a great opportunity for visual
              artists and film directors to deliver their work to new and widespread
              audiences.   
            As the technological and market barriers
              dissolve for real-time, interactive 3D worlds to be shared and transmitted
              over the internet, the notable successes are the content produced
              that leverages this powerful new media type.  
              Cyberspace will be what we make it! 
              In order to apply one’s creative talents to this new frontier,
              one must understand both the ‘sky-high’ view and be familiar with
              the nuts-and-bolts capabilities of the media. 
               
            We agree with industry pundits that design
              and programming skills are converging onto the digital graphics
              resume.  There will also
              continue to be an increased demand for visual software authoring
              tools that allow designers and producers to cross this chasm. 
            
            Foundation of the Frontier:  The World Wide Web
            
              - Networked
 
              - Interactive
 
              - Built on standards designed by Industry Consortia
                (W3C, Web3D, etc)
 
              - Principles guide us in the unkown: usability and compelling
                content
 
             
            Media Distinctions
            
              - Media:
                traditionally a way to transfer knowledge (communicate) using
                one mode of perception
 
              - 'Rich’
                Media: uses
                one or more modes of perception, usually
                dynamic (film, digital video, flash)
 
              - ‘Deep’ Media: extends
                rich media by adding another spatial dimension and describing
                scenes, objects, and interactivity.  You can embed Rich Media in a Deep Media environment.
 
             
            Industry Standards and Darwin
            
              - 3D
                file formats proliferating and fading 
 
              - Success
                will be a combo of: features, player distribution, and available
                content / applications 
 
              - VRML97
                is most established, most easily integrated; in addition, X3D
                promises to be extensible
 
              - ISO
                standards, open development (Web3D.org)

            The
              new standards like X3D
              (Extensible
              3D)
              coming from The Web3D Consortium and targeted for the International
              Standards Organization (ISO), and the Motion Pictures Experts’ Group
              (MPEG) promise greater speed, power, integration, and interoperability
              for deep media in the near term. 
              Some advances to look forward to in X3D: Lattice geometry
              compression, smoke and particle effects, Flocking behaviors, spline
              animation, and BSP tree/ portal management among others.
