Is our Max camera correct?

[GALACTUS]

Hi everybody

Came across this the other day thought it was quite interesting

http://www.cgtechniques.com/goodies/doftoy/index.php

In particular this statement

" also have to point to a 3dsmax problem:
3dsmax calculates the lens from the horizontal Fov value, but with the wrong aspect ratio!!!
I now understand that 3dsmax will never be able to match a real photography with it's maxcamera."

Why with all the revisions and patches in 3DSmax's lifetime, no one has bothered to implement or correct this is curious.

I am refering to the fact that our 3D cameras should work or have controls similar to their real world counterparts.

I'm sure there was a post about this on the forum a couple of weeks ago, by the guy who wrote the script and article - but I can't seem to find it using the search. It's got to be here somewhere.

I think he was trying to get Vlado to include it within VRay or something. Cool utility though!

I think this is the the thread...

That's the one! Can't believe I missed that .

well, wrong ...ok, i think the maxcamera is not accurate ..or at least the formular to calculate the focal length, which is my point of interrest.
Trying to match a rendering with a 28mm maxcamera to an image which was taken with a 28mm lens will fail.

I don't know if it is really so important, but it's an indicator for not understanding cameras.

Thats exactly what i have been trying to do, matching the max camera to image taken on a real camera with 28mm , the two just dont line up

Is it really that difficult for programmers to implement? I mean look at all the wonderful stuff they(programmers) are churning out these days.....
