Methods and apparatus for efficiently rendering, managing, recording, and replaying interactive, multiuser, virtual reality experiences

An apparatus, comprising:

• a volatile memory;
• a non-volatile memory;
• a first processor operatively coupled to the non-volatile memory, the first processor configured to receive a data set associated with an object and user information associated with a first spatial position of a first user with reference to the object and in a virtual environment, the data set including a spatial data series of the object,
• the first processor configured to receive a set of inputs from the first user, the set of inputs being associated with a set of predetermined properties associated with a portion of the object;
• a second processor operatively coupled to the volatile memory, the second processor configured to render, based on the user information and the set of inputs, an instance of the portion of the object in the virtual environment, the instance of the portion of the object being from a first perspective of the first user, the first perspective being based on the first spatial position of the first user,
• the second processor configured to receive manipulation information related to a manipulation of the instance of the portion of the object by the first user, the second processor configured to render, based on the manipulation-information, an updated instance of the portion of the object that manifests an effect of the manipulation in the virtual environment;
• and
• at least one of the first processor or the second processor configured to record media associated with the rendering of the updated instance of the portion of the object, the media including spatial information associated with the rendering of the updated instance of the portion of the object from the first perspective of the first user, the media being configured to be replayed to render the updated instance of the portion of the object from a second perspective of a second user at a second spatial position and different than the first perspective of the first user.

A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to:

• receive data including medical images associated with an object;
• extract a data set associated with a structure of the object and user information associated with a first spatial position of a first user with reference to the object in a virtual environment;
• receive a set of inputs from the first user, the set of inputs being associated with a set of predetermined properties associated with a portion of the object in the virtual environment;
• render, based on the set of inputs and the user information, an instance of the portion of the object in the virtual environment from a first perspective of the first user, the first perspective being based on the first spatial position of the first user;
• receive manipulation information related to a manipulation of the rendered instance of the portion of the object by the first user and in the virtual environment;
• render, based on the manipulation information, an updated instance of the portion of the object that manifests an effect of the manipulation in the virtual environment;
• and
• record media associated with the manipulation and the rendering of the updated instance of the portion of the object, the media including spatial information associated with the rendering of the updated instance of the portion of the object, from the first perspective of the first user, the media being configured to be replayed to render the updated instance of the portion of the object from a second perspective of a second user at a second spatial position different than the first perspective of the first user at the first spatial position.
