Abstract

The present invention provides a highly scalable architecture for a three-dimensional graphical, multi-user, interactive virtual world system. In a preferred embodiment a plurality of users interact in the three-dimensional, computer-generated graphical space where each user executes a client process to view a virtual world from the perspective of that user. The virtual world shows avatars representing the other users who are neighbors of the user viewing the virtual word. In order that the view can be updated to reflect the motion of the remote user'"'"'s avatars, motion information is transmitted to a central server process which provides positions updates to client processes for neighbors of the user at that client process. The client process also uses an environment database to determine which background objects to render as well as to limit the movement of the user'"'"'s avatar.

Claims

1-3. -3. (canceled)

4. A method for communicating information associated with a plurality of users interacting in a virtual environment, each user being associated with a three dimensional avatar representing the user, comprising:

receiving, at a client processor associated with a user, a control packet containing command information updating the positions associated with a plurality of avatars.

5. A system for displaying interactions in a virtual world among a local user and a plurality of remote users, comprising:

a database storing information associated with one or more avatars, each user being associated with a three dimensional avatar;

a memory storing instructions; and

a processor programmed using the instructions to;

receive position information associated with less than all of the remote user avatars,

receive orientation information associated with less than all of the remote user avatars,

generate on a graphic display a rendering showing the position and orientation of at least one remote user avatar, and

switch between a rendering on the graphic display that shows the virtual world to the local user from a third user perspective and a rendering that allows the local user to view the local user avatar in the virtual world.

6. The system according to claim 5, wherein the local user is associated with a custom avatar created based on input from the local user.

7. The system according to claim 5, wherein the local user is associated with an avatar selected from a fixed avatar image database.

8. The system according to claim 5, wherein the orientation information is further associated with a plurality of views of an avatar at different angles.

9. The system according to claim 8, wherein the plurality of views comprise a plurality of image panels.

10. The system according to claim 5, further comprising an audio processor coupled to the processor for generating and routing messages associated with audio signals received from a remote user to an audio device.

11. The system according to claim 5, further comprising a primitives database storing information describing how to render an object.

12. The system according to claim 5, wherein the processor is further programmed to receive input from the local user associated with movement of the local avatar and determine the movement of the local avatar relative to objects in the virtual world based on a non-linear model.

13. The system according to claim 12, wherein the non-linear model comprises model based on squared forward movement.

14. The system according to claim 5, wherein the processor is further programmed to limit the number of remote user avatars shown on the graphic display based on the proximity of the remote user avatars relative to the local user avatar.

15. The system according to claim 5, wherein the processor is further programmed to limit the number of remote user avatars shown on the graphic display based on the orientation of the remote user avatars relative to the local user avatar.

16. The system according to claim 5, wherein the processor is further programmed to limit the number of remote user avatars shown on the graphic display based on computing resources available to the local user graphic display.

17. The system according to claim 5, wherein the processor is further programmed to limit the number of remote user avatars shown on the graphic display based on a selection made by the local user.

18. The system according to claim 17, wherein the selection is independent of the relative position of the local avatar and the remote user avatars not shown on the graphic display.

19. The system according to claim 5, further comprising a rooms database containing information describing a plurality of rooms associated with the virtual world.

20. The system according to claim 19, wherein the processor is further programmed to allow an avatar to teleport between the rooms associated with the virtual world.

21. A system for displaying interactions in a virtual world among a local user and a plurality of remote users, comprising:

a database storing information associated with one or more avatars, each user being associated with a three dimensional avatar;

a memory storing instructions; and

a processor programmed using the instructions to;

receive position information associated with less than all of the remote user avatars,

receive orientation information associated with less than all of the remote user avatars,

generate on a graphic display a rendering of a perspective view of the virtual world in three dimensions which includes three dimensional renderings of the less than all of the remote users'"'"' avatars based on the received orientation and position information, and

change in three dimensions the perspective view of the rendering on the graphic display of the virtual world in response to user input.

22. A system for displaying interactions in a virtual world among a local user and a plurality of remote users, comprising:

a database storing information associated with one or more avatars, each user being associated with a three dimensional avatar;

a memory storing instructions; and

a processor programmed using the instructions to;

receive position information associated with less than all of the remote user avatars,

receive orientation information associated with less than all of the remote user avatars,

generate on a graphic display a rendering showing the position and orientation of at least one remote user avatars, and

switch between a rendering in which all of a perspective view of the local user avatar is displayed and a rendering in which less than all of the perspective view is displayed.
