Introduction – What is LVC Game?
• LVC Game is Calytrix‟ interface for VBS2, providing
various data and network services
– bidirectional DIS/HLA interconnection
– coordinate system transformations
– customizable entity mapping
• All LVC Game customers are entitled to download and
use all versions of LVC Game.
10
Introduction – What is LVC Game?
LVC Game is a DIS/HLA application built with Calytrix SIMplicity
DIS/HLA development tool, which provides FOM agility and RTI
(middleware) independence.
Calytrix SIMplicity supports:
• DIS
• HLA 1.3 and 1516
• Raytheon-VTC
• MAK Technologies
• Pitch
• DMSO ng6
• Portico
• RTI-s
11
Versions of LVC Game might
not always be available for
every RTI that SIMplicity
supports, depending on
customer demand for different
versions of LVC Game. Contact
Calytrix for details.

Reckoning thresholds or the Entity Heartbeat time limit has been reached.
• DIS-standard Dead Reckoning algorithms:
LVC Game supports: Static (algorithm #1), FPW (alg. #2), FVW (alg.#5)
LVC Game does not support: RPW, RVW, FPB, RPB, RVB, FVB

LVC Game Capabilities
Two options to control and/or interact with VBS2 entities:
1) Vary VBS2 entity parameters
• quick and easy GUI interface to adjust parameters
• offline and realtime editing modes
• obviously limited to those parameters of VBS2 models and
behaviors which are exposed to users
2) Control and/or interact with VBS2 entity by using an external math
model communicating with LVC Game via DIS/HLA
26
LVC Game Capabilities
Life is good … but not perfect.
• DIS/HLA was developed without concern for VBS2
• VBS2 was developed without concern for DIS/HLA
• Examples:
• VBS2 displays an individual‟s stance & orientation, but not all
connected systems use or publish such info
• Orientation of tank turrets is visible in VBS2 but not used by
some external systems, or tank turret orientation info may
not be available (e.g., not in the FOM)
27
Important Points to Consider
• Separate, correlated terrain databases are needed
• VBS2 terrain in VBS2 format
• 200 km * 200 km, approximate maximum extent
• VBS2 terrains are often very detailed & smaller in extent
•
OneSAF terrain in OTF format
• SWA database = 9 geocells
• Number of entities
• VBS2 … a few hundred entities (within its space), with
performance improvements under development to expand to
~2000 entities
• OneSAF … 30,000 entities
