One thing to remember when reading about DOF is that Indigo does not use the same format for aperture as a camera does. For a camera when you set an aperture of f/4 this means that "the aperture opening has a diameter of the focal length divided by 4". Indigo uses radius, not diameter so the convers...

It looks very realistic

Perhaps the working directory isn't set correctly when it fails?

Hi,

If the subject is the Atlantic ocean I don't think Cauchy B is very important since dispersion is not very pronounced in this case. A glass of Atlantic ocean water would be different of course.

Heya ryjo, thanx mate for your contribution. Could you explain in a simple way how to calculate the cauchy_b ... ? :D :D :D ;) take care psor Hi, In the Cauchy equation ior is computed as IOR(L) = A + B/L^2. By taking the difference between two wavelengths you get IOR( L1 ) - IOR( L2 ) = B / L1^2 -...

But now I'am interested.... there is a <cauchy_a_coeff> commmand too?!??

I assume that if cauchy_b_coeff is non-zero then ior should be given as Cauchy A.

Perhaps Ono can comment?

Hi,

I think that 0.044 is not Cauchy B for diamond (it is another measure for dispersion used in the gem industry). I computed a value of 0.013948 for Cauchy B and 2.3744 for Cauchy A, based on data in Diam.nk.

Cheers,

Hey Ono-Sendai... Is it posible to add Process Priority definition to the inifile.txt, so I (and everybody else :roll:) don't always have to change it by hand, if I want to keep working on my PC? I think this is a loooooow Level Request, kind of luxus, but still handy :wink: Hello :), psExec (sysin...
