1. Definition

Virtual Environment Data In (VE Data In) consists of a variety of Data Types extracted from the Virtual Environment including the Scene (Performers and Stage or Performance Set), Participants, and Operators.

2. Functional Requirements

VE Data In includes data three elements describing the Virtual Environment:

  1. Performance Data includes data describing all elements of the entire Virtual Environment Scene (including terrain, foliage, architectural structures, performers’ avatars, autonomous avatars) and their properties (Spatial Attitudes, animations, lighting, textures/materials, and effects).
  2. Participants Data includes data describing participants’ avatars and their properties (Spatial Attitudes, animations, lighting, textures/materials, and effects).
  3. Operator Data includes data from remote show operators acting on the metaverse.

Data entering the XRV-LTP belong to the following categories:

  1. 3D Model representing scenes and visual
  2. Audio Data includes audio from virtual microphones and all audio sources.
  3. Visual Data includes visual data from 2D virtual cameras and all other visual sources.
  4. Biometric Data includes biometric measures of performers and participants.
  5. App Data from performer and participant devices.
  6. Controller Data from performer and participant devices.
