pfilt: picture too dark or too bright

hi Giovanni, the test01_sky.rad file includes the bright function definition of the sky but does noy apply it to any geometry, probably you need to include the sky definition, i cant try it because i have not the perezlum.cal file

skyfunc glow sky_glow
0
4 1 1 1 0

sky_glow source sky
0
4 0 0 1 180

Regards,
Ignacio

Dear all,

I am having a problem when trying to generate an hemispherical view of
the sky using GENDAYLIT, I always retrieve the error

pfilt: picture too dark or too bright

Which sounds like the whole image is white. I do not have the same error
when using GENSKY, no matter how high the values for -B and -R are.

Any hint?

How can I generate an accurate image of the sky dome using gendaylit?

Thanks for your help

Giovanni

Thanks Ignacio,

Of course!
Now I see that was a pretty silly question! Thanks!
