What future lies ahead for computing as the Internet and its associated infrastructure expand? Will the network be able to cope with rising demands for carrying capacity and response speed? Will it change the way scientists, designers, artists, computer professionals, and home users work in the future? These are some of the wideranging questions being asked about the Internet and World Wide Web.

Increases in computational power and control methods enable the creation of 3D virtual humans for real-time interactive applications. 1 Artificial intelligence techniques and autonomous agents give computer-generated characters a life of their own and let them interact with other characters in virtual worlds. Developments and advances in networking and virtual reality (VR) let multiple participants share virtual worlds and interact with applications or each other.

It is concluded that AR adds a real sense of learning to mobile games by providing models of real world settings for learners. The learning objectives must be integrated into the game rules, story and different levels. The game model must be close to the real world; each team member must have distinct roles; resources must be constrained and appropriate feedback and challenges must be used throughout the game system. By using this emerging paradigm of instruction, educators can effectively incorporate these games into their curricula.

After conceptual analysis of the subject matter i.e. computer's motherboard, the game was designed. The action within the game is consistent to the theme. There is a story, simplifying and exaggerating real life. Elements of control, feedback and sense of danger are incorporated into our game. By producing an engaging learning experience, vocabularies were learned incidentally. Deliberate vocabulary learning games were also added to our package to help students solve their common errors.

Computation was used as a simple tool to evaluate algorithms or transform data into some appropriate pictoral representation. Thus standard computer graphics texts have little to say about numerical methods, just as earlier numerical analysis textbooks had little to say about computer graphics. This is now changing, for the important reasons outlined in this paper.

Much of modern physics is a result of the superior abstract visualization abilities of a few brilliant men. Newton visualized the effect of gravitational force fields in three dimensional space acting on the center of mass. And Einstein visualized the geometric effects of objects in relative and uniform accelerated motion, with the speed of light a constant, time part of space, and acceleration indistinguishable from gravity. Virtually all comprehension in science, technology, and even art calls on our ability to visualize. In fact, the ability to visualize is almost synonymous with understanding. We have all used the expression "I see" to mean "I understand." 1 T he need to make sense of complex, conflicting, and dynamic information has provided the impetus for new tools and technologies that combine the strengths of visualization with powerful underlying algorithms and innovative interaction techniques; tools that make up the emerging field of visual analytics. 2 Visual analytics is the formation of abstract visual metaphors in combination with a human information discourse (usually some form of interaction) that enables detection of the expected and discovery of the unexpected within massive, dynamically changing information spaces. It is an outgrowth of the fields of scientific and information visualization but includes technologies from many other fields, including knowledge management, statistical analysis, cognitive science, decision science, and others.

The algorithm works well in dynamical and un-configured environments, and is able to produce a collision-free, time -optimal motion trajectory in order to find a navigation path. In addition to the motion constraint path planning, our approach can deal with the unknown obstacle-space terrains to moving agents. It therefore solves the drawbacks of traditional obstacle-space configuration methods. Multi-agent behaviour has been explored based on the algorithm. In the simulation a simple physically-based aircraft model has been developed, which is addressing the manoeuvring capabilities of the moving agents, while the moving agents' accelerations and velocities are always continuous and bounded. The generated motion path is constituted smoothly and has continuous curvature on the whole state space of the motion, thus satisfying the major requirement for the implementation of such strategies in real-time animation or in simulation applications in VR environments.

The paper details the techniques for communication, scene management, facial and body animation, and general user interaction modules. The use of VRML97 and MPEG-4 SHNC is overviewed to stress the compatibility of the system with other similar Virtual Reality systems. The software provides realistic virtual actors as well as sets of applicable high-level actions in real-time. Related issues on obtaining actor models and animating them in real-time are presented. The creation process of an attraction incorporates assembling animation units through a timeline. Using this software, users are then able to introduce their own scenario-based applications into a shared virtual environment.
