Systems and methods for providing secure portals between virtual worlds

Abstract

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.

Dependencies are inferred from the claim text.
