Application Production Process and tools Commerce using MPEG-4 on Internet with QoS Project Leader : Christian Bertin, CCETT
Applications VIRTUGUIDE Application Home shopping application for Turism Products (extended city trips) VIRTUCAT Application Home shopping application for Commercial Centre products (sport, video, etc.)
VIRTUGUIDE Application - Young overstyled blonde - History student - Charismatic artist type - Techno D.J.ane - Jobless coffeedrinking actor 360-degree prerecorded video sequence so you can see in any direction around you A set of recommended choices (appearing and disappearing) for interaction A global map of Berlin with the guide position A local map (zoom on global Berlin map) with the guide position As you follow your guide through Berlin, you can see in addition to the 3D Video: You are following one of the 5 guides through Berlin :
VIRTUGUIDE Screen HTML Page consisting in : Applets (global map, local map, recommended choices) MPEG-4 3D Scene with a video displayed on a hemisphere) Problem : Text display quality is not acceptable in VRML/MPEG-4 => Java AWT.
VIRTUGUIDE Application Characteristics 360 degree shooting with a hemispheric mirror above the camera : 512x512 pixels Future : Video divided in 8 planar video segments Circular video to be mapped on a hemisphere Future : Only 3 or 4 Video segments sent at a time to be mapped on a cylinder

VIRTUCAT Application Bike shop screen Do it yourself! Please select : - a frame, - a fork, - a wheel and you will see the result : a 3D model of your bike with all the selected elements together You can go around the bike you are building yourself You can browse the sets of frames, forks and wheels for selection You can order your bike (BUY button) You can go back to the shop selection
VIRTUCAT Screen Characteristics MPEG-4 Scene with : 2D scene with 2D textures 3D Bike Model HTML pages for order form Server ASP Script to handle the contents of the customer trolley and corresponding order form
VIRTUCAT Production Process 3D Commercial centre Tower Navigation production (Lightwave, 3D Studio Max, convertion to MPEG-4 with some limitations due to the Compositor 3D Bike model Production (Filmakademie, 3D S. Max) 2D Textures (Frames, Forks, Wheels) (Filmakademie, JPEG encoding) Bike Shop Screen composition (CCETT, no 2D tool, text editor only)
VIRTUCAT Production Process (continued) EAI (Enhanced Authoring Interface) Java Programs (to get the selected bike elements and to position the bike elements) ASP Script behind BUY button to run on the server (Finsiel)

Electronic Commerce Requirement on MPEG-4 We will use MPEG-4 only when MPEG-4 Tools and Servers offer : User input to get Password, User ID, User Address, User Comments, Order Forms, Database Product Search Criteria, etc. Dynamics in scene using scene skeleton and dynamic elements updated with information coming from a database (price, product description, product pictures, product videos) Possibility to jump at a Random Access Point in an MPEG-4 scene
