ABSTRACT:
Methods, systems and computer program products are provided which display an animation in a three dimensional virtual environment by associating the animation with a parent transform such that the geometry of the animation is transformed so that the animation is viewed from a predefined point of view with respect to a user in the three dimensional virtual environment. The animation may, optionally, be played for the user when the user is located in a predefined area of the three dimensional virtual environment. Preferably, the predefined point of view is facing the user. In a VRML embodiment of the present invention, the parent transform is a VRML billboard transform such that a VRML billboard node is created utilizing an animation as a child to the billboard node.
