Hi All,

i need to calculate the focal, aperture for a raycam.

I see that i have 2 value to get it:
zoom and scale.

form SDK:
Vector scale
The camera scale, this is the screen scale, including focal length, aperture etc.

Any help to calculate the focal and aperture from the scale vector?

Cheers
Renato

From what I can see you can get only the Field Of View from the RayCamera scale.

field of view = arctan(xres/scale.x/2)*2

the field of view contains the aperture and the focal length

field of view = arctan(aperture/focal/2)*2

the scale.x and scale.y ratio is the pixel aspect ratio

Otherwise couldn't you get focal length and aperture by accessing the RayCamera's link parameter?

cheers,
Matthias
