摘要： Methods, systems and computer program products are provided which transport a user in a virtual reality environment from a first location to a second location by providing a transportation vehicle that receives the user at the first location, receiving a destination signal from the user which indicates the second location as a destination, transporting the user in the transportation vehicle to the second location independent of any user input, and providing customized information to the user when the user is in the transportation vehicle. The transportation may be inter-world or intra-world. The customized information can take any number of forms such as dynamic visual scenery, audio messages, static visual graphics, video images, or any combination thereof.

摘要： 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.
