Q:
The MumbleLink memory file does not seem to provide enough data to reconstruct the camera projection matrix. Specifically, it only specifies the position, direction, and top, but not the FoV. Does anyone know what angle the FoV is? Thanks
Camera FoV
The vertical FoV is resolution independent and should be approximately tan(77.6*PI/90).
The horizontal is resolution dependent, which cause some problems in wvw with arrow carts.
16:9 resolution about tan(70*PI/90)
5:4 resolution about tan(75*PI/90)
16:10 resolution about tan(71.4*PI/90)
This numbers are determined manually over some fix points in game and are working in my project https://bitbucket.org/draos/guildwars2-battle-hud very well. (file utimer.pas)
