Requirements:

• Variable Mounting
  • Attachment must be able to fit varying barrel diameters.
• Variable Intensity
  • This will allow for varying degrees of gunshot firepower, and can account for individual or creative preferences.
• Illumination
  • Muzzle flash must be intense enough to light up nearby surfaces, as well as faces of actors to simulate realism.
• Randomness
  • Flash must have subtle intensity and shape variation.

Constraints:

• Specific Actuation
  • Must flash when the trigger is pulled (even without cocking), or when recoil is simulated.
• Silent Actuation
  • Relying on sound detection to trigger flash, or requiring a loud mechanical system to operate, will add noise interference to sound design during production.
• Short Duration
  • To mirror real gunshots, the flash must be about 2-5ms.
• Compact Design
  • The design must be compact enough to fit on pistols and other handguns without being disproportionately large, which breaks realism.
• Open Barrel Design
  • To mimic real gun attachments, and ensure safety on the event a shot or blank is fired, the design must have an unobstructed, open end to allow for the passage of projectiles.
• Forward Flash
  • Flash should fire within a narrow beam angle to imitate real physics.
• Low Latency
  • Actuation must occur below typical human perception timeframes, less than 15ms.
