Camera Matching With Maya

[dunkel3d]

hi, i created a scene in maya, using the default camera , so horizontal aperture is 1.417 and vertical 0.945 with a 35 mm lens and an angle of view of 54.43.

i open the scene in nuke , imported the obj model and the apply the texture using this data camera aperture H 24.576 V 18.672 and a 38 mm lens.

well the 2 project were matching with no problem.

i tried to convert the unit from mm to inches but all the value are appoximative not precise.

so are the maya project and the nuke one matching but not perfectly..... just becouse are similar?

thanks in adavance.

I'm not sure what you're doing exactly but if you have a Maya cam with a film back of 1.417" x 0.945" you should multiply that by 25.4 to get mm.
So in your case that would be 35.9918m x 24.003mm
once the film back is the same size you should get the same focal length as well (i.e. 35mm not 38mm)

so a camera with a film back of 35.9918 x 24.003 and a focal length of 35mm gives you a horizontal fov of 54.4216 degrees
A camera with a film back of 24.57 x 18.672 and a 38 mm lens shuld give you a 35.8309 degree fov so I don't know how those two can possibly match!?

cheers,
frank
