Systems and methods for providing secure portals between virtual worlds
Systems and methods for secure portals between virtual worlds are provided. In some embodiments, the systems and methods include deploying a secure portal between two virtual worlds. This is performed by rendering a top cell for a first virtual world. Rendering includes a transparent region overlapping a portal. Then an intermediate cell is layered underneath the top cell. This intermediate cell comprises the portal. A message is received from the top cell. The message includes a minimum rendering size, shape and at least one transform. This message is transferred to a bottom cell for a second virtual world, where it is rendered (in part) responsive to the message. The top cell, the intermediate cell and the bottom cell are then layered to generate a scene. In some embodiments, the rendered portion of the bottom cell comports to the minimum rendering size, and the intermediate cell is transparent. In some cases, the cells are either iFrames, or separate applications.
1 . A method for deploying a secure portal between two virtual worlds comprising:
rendering a top cell for a first virtual world, wherein the rendering includes a transparent region overlapping a portal;
layering an intermediate cell underneath the top cell, wherein the intermediate cell comprises the portal;
receiving a message from the top cell comprising a minimum rendering size, shape and at least one transform;
transferring the message to a bottom cell for a second virtual world;
rendering a portion of the second world responsive to the message; and
layering the top cell, the intermediate cell and the bottom cell to generate a scene.
2 . The method of claim 1 , wherein the portion of the second world is the same size as the minimum rendering size.
3 . The method of claim 1 , wherein the intermediate cell is transparent.
4 . The method of claim 1 , wherein the cells are iFrames.
5 . The method of claim 1 , wherein the cells are separate applications.
6 . The method of claim 1 , wherein the first virtual world is a user's location.
7 . The method of claim 6 , further comprising receiving an input from the user to interact with the portal.
8 . The method of claim 7 , wherein the interacting is one of selecting the portal or causing an avatar to travel through the portal.
9 . The method of claim 1 , further comprising reordering the top and bottom cell responsive to the interacting.
10 . The method of claim 1 , wherein the at least one transform is generated based upon the view of a user.
11 . A computer program product stored on non-transitory computer medium which, when executed by a computer system, performs the steps of:
rendering a top cell for a first virtual world, wherein the rendering includes a transparent region overlapping a portal;
layering an intermediate cell underneath the top cell, wherein the intermediate cell comprises the portal;
receiving a message from the top cell comprising a minimum rendering size, shape and at least one transform;
transferring the message to a bottom cell for a second virtual world;
rendering a portion of the second world responsive to the message; and
layering the top cell, the intermediate cell and the bottom cell to generate a scene.
12 . The computer program product of claim 11 , wherein the portion of the second world is the same size as the minimum rendering size.
13 . The computer program product of claim 11 , wherein the intermediate cell is transparent.
14 . The computer program product of claim 11 , wherein the cells are iFrames.
15 . The computer program product of claim 11 , wherein the cells are separate applications.
16 . The computer program product of claim 11 , wherein the first virtual world is a user's location.
17 . The computer program product of claim 16 , when executed by the computer system further performs the step of receiving an input from the user to interact with the portal.
18 . The computer program product of claim 17 , wherein the interacting is one of selecting the portal or causing an avatar to travel through the portal.
19 . The computer program product of claim 11 , when executed by the computer system further performs the step of reordering the top and bottom cell responsive to the interacting.
20 . The computer program product of claim 11 , wherein the at least one transform is generated based upon the view of a user.
