As mentioned earlier, a 3D virtual world is a mix of 3D gaming technology, augmented reality, simulated environment powered with Internet technology where users interact through movable
avatars. Users create avatars on the Web and allow them to reside in the virtual worlds. Learners can create their own avatars on the web & reside in these worlds. Virtual worlds can be seen as the beginning of new era of e-learning as they allow learners to do role-play, 3D modeling, simulations, creativity and their active involvements.
