Hi,
What is the equivalent of irradiance in POV-Ray? I can't seem to find any
information in the help document.
Thanks.
Daniel.

If you're referring to "irradiance" in VirtuaLight, then you should check
out the POV feature called "radiosity." They're basically the same feature,
with the same underlying algorithm. Interestingly enough, VirtuaLight's
"irradiance" feature exhibits the same corner-splotchiness as POV's
radiosity, which leads me to believe that the underlying algorithms
(specifically the parts that that re-use sample data) are VERY similar.

Thanks Nathan. It turned out that what I was looking for is the
recursion_limit in radiosity. Thanks again. It is called
irradiancebouncelevel in Virtualight. They are both exactly the same.
Currently, I'm trying to recreate the teapots scene provided in
Virtualight's example folder using POV-Ray. It is a good way to learn as I
needed to look up on lots of features in POV-Ray in order to recreate a
complex scene, which I would not have thought of if I would create my own
scene. So far so good, except I couldn't get the colour right even though I
use the same rgb stated in Virtualight's scene file. The colour of the
rendered image is lighter.
Regards,
Daniel

Gamma settings?
Read the "assumed gamma" thread in this same newsgroup.

Tried changing the assumed gamma, no changes :-( Thanks for the suggestion
though.

Daniel.
