Methods and Systems for Representing a Scene By Combining Perspective and Orthographic Projections

Abstract

An exemplary virtual reality content generation system manages state data representing a virtual reality scene. Based on the state data, the system generates a scene representation of the virtual reality scene that includes a set of surface data frame sequences each depicting a different projection of the virtual reality scene from a different vantage point. The different projections include a plurality of orthographic projections that are generated based on orthographic vantage points and are representative of a core portion of the virtual reality scene. The different projections also include a plurality of perspective projections that are generated based on perspective vantage points and are representative of a peripheral portion of the virtual reality scene external to the core portion. The system further provides the scene representation to a media player device by way of a network.

Description

BACKGROUND INFORMATION[0001]Various immersive technologies (e.g., virtual reality technology, augmented reality technology, mixed reality technology, etc.) allow users of media player devices to experience immersive scenes that are different from a real-world environment within which the users and media player devices actually exist. For example, a virtual reality scene may be generated based on camera-captured scenery of a real-world scene or virtually-rendered scenery of a virtualized scene. Using an immersive technology such as virtual reality technology, users experience simulated scenes that may be difficult, expensive, or impossible to experience otherwise. Accordingly, virtual reality technology may provide users with a variety of entertainment, educational, vocational, and / or other enjoyable or valuable experiences that may otherwise be difficult or inconvenient for the users to obtain.[0002]In some examples, virtual reality data is streamed from a content generation system ...

AI Technical Summary

Benefits of technology

The patent describes methods and systems for combining perspective and orthographic projections to represent virtual reality scenes. This approach allows for a more immersive and realistic user experience. By using both types of projections, the system can capture the core and peripheral portions of a scene, providing benefits from both approaches while avoiding downsides. The technical effect of this patent is to provide a more immersive and realistic user experience through a combination of perspective and orthographic projections.

Problems solved by technology

Using an immersive technology such as virtual reality technology, users experience simulated scenes that may be difficult, expensive, or impossible to experience otherwise.

Accordingly, virtual reality technology may provide users with a variety of entertainment, educational, vocational, and / or other enjoyable or valuable experiences that may otherwise be difficult or inconvenient for the users to obtain.

Unfortunately, various resource limitations (e.g., limited network bandwidth, limited computing resources of the content generation system for generating projections, limited computing resources of media player devices for rendering and presenting content, etc.) prevent systems from achieving this theoretical ideal.
