1. Functions

The Environment Description (XRV-END) AIM:

  1. Captures raw Data from the Real and Virtual Environments including audio, visual, and other data in a variety of formats defined by the Qualifier standard.
  2.  Using Script-Venue Associations, identifies and separates Performance elements, Participant elements and Operator elements which are relevant to subsequent processing:
    1. Performance elements include Position, Orientation, and behaviour of individual Performers and objects in the scene.
    2. Participant elements include Position, Orientation, and behaviour of individual Participants and their group behaviour.
    3. Operator elements include actions performed by Operators on Lighting, Audio, Video, and Show Control Consoles.
  3. Packages the elements into Performance, Participant, and Operator Descriptors for both the Real and Virtual Environments, and a combination of all Descriptors called Show Descriptors.
  4. Passes the Descriptors to downstream AIMs.

2. Reference Model

3. I/O Data

Table 1 specifies the Input and Output Data of the Environment Description (XRV-LTP) AIM.

Input Description
VE Data In Data entering the XRV-LTP instance from a Virtual Environment.
VE Venue Specification Specification of the VE Venue hosting the performance.
RE Data In Data entering the XRV-LTP instance from a Real Environment.
RE Venue Specification Specification of the RE Venue hosting the performance.
Participant Data Non-identifying information about each Participant loaded into the system and modified in real time.
Script A machine-readable functional description of the entire show performance including actions to be performed in the Real and Virtual Environment based on the Performance, Operator, and Participant behaviours.
Action Table Commands required to achieve a desired Action in the Real and Virtual Environments per the Script.
Script-Venue Associations Metadata that associates measurable elements of the Script (e.g., characters, objects, participants, operator consoles) with data sources and sinks specific to the Real and Virtual Environments, as defined by the Qualifiers in the Venue Specifications.
Output Data Description
RE Performance Descriptors Descriptors of Real Performers and Real Objects (stage, set pieces, and all associated objects).
VE Performance Descriptors Descriptors of Virtual Performers and Virtual Objects (the entire environment, including virtual stages, set pieces, and all associated objects).
RE Participant Descriptors Descriptors of Real Participants, Real Participant interaction zones (seating, pathways, rooms, etc.), and Real Participant responses.
VE Participant Descriptors Descriptors of Virtual Participants, Virtual Participant interaction zones (seating, pathways, rooms, etc.), and Virtual Participant responses.
RE Operator Descriptors Descriptors of Real Operator actions on the consoles.
VE Operator Descriptors Descriptors of Virtual Operator actions on the consoles.
Show Descriptors The collection of all RE and VE Descriptors as required by RE and VE Experience Generation AIMs.
Participant Data Non-identifying information about each Participant updated in real time as the Performance evolves.
