Physical Sky Shader

[Willi]

hi all,

 

here is a preview of my new shader that i am developing.

its a physical sky shader based on "preetham´s" paper.

at the moment it is only an ambient shader that can be applied on an "environment sphere" for background renderings.

it can be controlled by a light or by date, time, longitudes and lattitudes.

i hope it can be also implemented for sampling an ambient occlusion environment, so that we also have one more option in the "global ambience" slot...

Woah! Now that is sweet!

 

Thanks for the preview Willi!

 

I think this is the site (or at least a site) that published the paper: http://www.cs.utah.edu/~shirley/papers/sunsky/

no clouds.

In the northern hemisphere the sun will set from upper left to lower right. Something is reversed.

[Willi]
