Abstract

The present invention provides a computer implemented method and apparatus to project a projected avatar associated with an avatar in a virtual universe. A computer receives a command to project the avatar, the command having a projection point. The computer transmits a request to place a projected avatar at the projection point to a virtual universe host. The computer renders a tab associated with the projected avatar.

Claims

1. A computer program product for projecting an avatar in a virtual universe, the computer program product comprising:

one or more computer readable tangible storage devices;

program instructions, stored on at least one of the one or more storage devices, to receive a command to project the avatar, the command having a projection point in the virtual universe, wherein the avatar represents a user and can interact with objects in the virtual universe;

program instructions, stored on at least one of the one or more storage devices, to copy a geometry of the avatar to form a projected avatar, wherein the projected avatar occupies the projection point;

program instructions, stored on at least one of the one or more storage devices, to apply a rendering effect to the projected avatar, the rendering effect being distinct from a rendering effect applied to the avatar, wherein the rendering effect applied to the projected avatar is transmitted to a client computer;

program instructions, stored on at least one of the one or more storage devices, to receive a command to swap the avatar with the projected avatar, the avatar having a departure point;

program instructions, stored on at least one of the one or more storage devices, to teleport the avatar to the projection point; and

program instructions, stored on at least one of the one or more storage devices, to teleport the projected avatar to the departure point.

2. The computer program product of claim 1, wherein the program instructions to teleport the avatar:

associate the avatar with the projection point to form an association of the avatar with the projection point;

transmit the association of the avatar with the projection point to the client computer; and

transmit an avatar attitude to the client computer.

3. The computer program product of claim 1, further comprising:

program instructions, stored on at least one of the one or more storage devices, to apply physics to the projected avatar such that a virtual universe object interacts with the projected avatar according to a conservation of momentum.
