Sky radiance model

Dear Greg,

Thank you for your advice. I'll do my best.

Cheers,

Ehsan

Well, you can follow the example in skybright.cal to translate your
equations to something Radiance can use directly. The documentation is in:

http://radsite.lbl.gov/radiance/refer/filefmts.pdf

And there are tutorial chapters in "Rendering with Radiance" if you have a
copy of that.

Note:
By radiance distribution and radiance fraction I meant ratio of radiance
of each patch over sum of radiance of all patches.

Best,

Dear Greg,

I developed a model which applies angular distance between any point on
the sky and Sun disc to calculate radiance fraction and then having
radiance distribution and horizontal diffuse irradiation, radiance or even
luminance of each point under clear sky condition can be calculated! I hope
this information can be useful:)

Cheers,

Hi Ehsan,

There are ways to do this, but you need to be a little more specific
about what data you are starting from. Otherwise, it's difficult to offer
direction.

Best,

Hi Everyone,

I have a radiance distribution model over the sky dome, is there a way
to use my model to generate the sky not using gensky or gendaylit?

Cheers,

Ehsan
