Sun angular size parameter #9

Closed mdkdy closed 7 years ago

Currently sun angular size has effect on how fast direct radiance fades when sun hides beneath the horizon. http://i64.tinypic.com/14jyoh0.png Correct me if I am wrong but should it also have effect on how fast sky radiance or indirect radiance fades into night or day during sunset or sunrise?

I updated the single scattering and direct irradiance computations to take the Sun angular size into account, but it makes no visible difference.
