Multimedia Authoring I: VRML

Advantages:• 3D Scenes• Web-Based• Cross Platform• Multimedia Support• Text-based file

VRML: Expected Extensions• Efficient Behavior Control: VRML+JAVA• Multi Users Support: VRML+JAVA• Convenience in Navigation:

VRML+JAVA+PROLOG, for navigation assistants

• Intelligent virtual agents: VRML+JAVA+PROLOG

Why DLP

• Object-oriented parallel prolog• Web3D support• TCP/IP support for network

communication• Java-based. All DLP programs

are compiled into java classes• Efficiency for programming• Reasonably good performance

STEP: a scripting language for embodied agents

(Scripting Technology for Embodied Persona)

FACT : STEP Source Code (1.0)

Schedule: LecturesMonday, 11.00-12.45, Room S111, Week 18-

21,24-26• Introduction and Demonstrations. • PROLOG and DLP • DLP for Virtual Environments • Agent, Web Agent, 3D Web Agent• Avatar Design and Control• STEP: a scripting language for 3D

agents

Schedule: Practical Work and Exercises

• Thursday 15.30-17.30• Computer Lab S353 (S345), Week 19-

20,23-25• Use Internet Explorer for VRML

Browser (Blaxxun)• DLP works under Microsoft Java Virtual

Machine.• Do not use Netscape and Firefox which

rely on Sun Java Virtual Machine to run DLP compiled Java applets.

Final Assignment• Jointly work on a project in teams of two. • Register your team to huang@cs.vu.nlBefore Week 23• Report your system design in Week 26• Submit your work before Sept. 30, 2006.
