1. Definition
An input to the Environment Description and the Real Experience Generation AIMs defining protocols, data, metadata, and command structures for the specific Real Environment Venue. The RE Venue Specification consists of 3D Model Scene Descriptors that define the physical structure, position, and orientation of fixed objects plus an inventory of 3D Model Objects which do not have a specific position in the Venue. In addition, each object within the 3D Model Scene Descriptors and 3D Model Objects have an associated Annotation that specifies all the information necessary to characterise and send/receive data to/from that object. Annotations are typically application dependent. However, the XRV-LTP specification provides some Annotation examples for typical use including Lighting Fixtures, MoCap devices, Biometric devices, Cameras, MIDI devices.
2. Functional Requirements
This includes number, type, placement, and parameters of:
- DMX/RDM Universes and their associated Channel definitions for all Lighting fixtures, Special effects, DJ and VJ consoles, rigging, elevator stages, prop motions, pyro, and miscellaneous sensors.
- Audio sources (e.g., microphones, audio players) and formats.
- Visual sources (e.g., 2D/3D cameras, video servers, and all other video sources) and formats.
- Motion Capture devices (e.g., performer motion and object motion tracking).
- LiDAR sources (e.g. scans of performance and participant areas).
- Biometric sensors from performers and participants.
- Time Code Data formats.
- MIDI devices and their associated Channel definitions.
- App Data from performer and participant devices.
- Controller Data from performer and participant devices.
- Seating chart (Spatial distribution of individual seats).
