0.962653 Horizontal FOV (degrees)

Explanation

Formula context fixed at 32:9. DFOV converts to HFOV using trig relations on the half-angle tangent model.

For Diagonal FOV to Horizontal FOV, the active game/FOV profile determines the conversion constants applied to every value.

Keep the same profile in both directions to avoid mixing lookup systems that use different size mappings.

Method & Reference (Verified)

  • Method basis: profile-bound mapping; constants depend on the selected profile encoded in the route.
  • Profile reference: game/FOV profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
