auto- focal length

[fortunate reee]

hey @DPI Wizard i have recently had great success with the whole focal length custom res calculations

and at that point i started hypothesizing about a potential implementation of this calculation

https://www.geogebra.org/classic/wg83gxjc

 

 

if you could select    ^ focal length as an aspect ratio that would be interesting ( keeping the native fov modifier )

and just locking the resolution to the respective custom res

 

could simplify the application of this process ,it is very niche so it not being viable  option would make sense

interested in hearing your thoughts on it

 

keep up the great work

I would greatly appreciate this too! I've even thought about making my own post about it but never got around to it

https://www.geogebra.org/classic/wg83gxjc is a great resource but a very tedious process, and lately I've noticed for a lot of games where you can't change FOV, the FOV box in the calculator becomes grayed out and I can't use my calculated FOV to convert from/to other games that way either.

I too would love to see this feature.

How exactly are you using this in the calculator?

you set fov 1 ( alpha/ game you want to convert from)

you set fov 2 ( beta / you wish to convert to)

 

you set then custom res you get as a result as game 2s resolution in the calculator

and the focal length isn't as far off when you cant natively match the fov thus the

pixels/count stay closer to the original and you can maintain teh sens

this would be the focal length matched destiny (100.8 fov beta matched from 73.74vdeg/106.26 alpha )as an example

 

for 73.74 vdeg this would end up with those numbers or something close for destiny and 103 fov games like overwatch and valorant

it is just a bit of a hastle to redo the geogebra thing every time i wish to change the base fov so an implementation would be very beneficial

my initial thought was to create a stretched /black bars option "focal " that would take fov alpha match it to Beta in a similar fashion to the geogebra thing and then automatically insert the matched res in the game b resolution allowing for simplified use with the calculator

 

im unsure how doable this would be from a math / implementation stand point but i must say whatever we can get would likely be  a step up from what we have to do now

It is just:
OutputGameResolutionWidth  = InputGameResolutionWidth * ((tan(OutputGameVerticalFov * pi/360)) / (tan(InputGameVerticalFov * pi/360)))
OutputGameResolutionHeight  = InputGameResolutionHeight * ((tan(OutputGameVerticalFov * pi/360)) / (tan(InputGameVerticalFov * pi/360)))

Now OutputGame has the same vertical fov in the same screenspace as InputGame.

Should be no problem implementing this so the resolution in the output game changes. Are you actually setting this as a custom res in Windows or the game to match?

I set the custom resolution in game (Windows remains unchanged) and have turned off scaling in the Nvidia control panel, so black borders on all four sides at 16:9. With hor+ games, where fov extends horizontally without cropping the top and bottom, I just lower the height and keep the full width of my monitor.

im just creating the custom res to then use in the game with black bars works like a charm
