NRL HCI Lab VE Software Review

Requirements and Nice-to-Haves:

• Logging: Statistical/Event/Timing Logging Capabilities
• Importing: Ability to Import (or Easily Convert) Models in Standard Formats
• Framerate: "Real-time" Framerate
• Collisions: Collision Detection for Limbs/Guns, etc.
• Source Code: Design, Maintainability
• Platforms: Portability (Win-NT/IRIX/Linux)
• Graphics: High-Level, Mid-Level, Low-Level
• Input Devices: Support, Interchangeability
• Scalability: Will use all available processor resources
• Networkability: DIS? HLA? Proprietary
• Comments: General relevant comments
