[Radiance-general] ambient accuracy parameter

[Mark de la Fuente]

Mark,
 
Awesome pictures.  What are the limitations of your low -ad and high over sampling approach?  When is appropriate and when is it not appropriate?
 
Probably not something you are concerned about in your work, but when you use such a low -ad setting and such a high over sampling rate, I'd like to know what effect there is on overall light level accuracy in a typical interior space with daylighting and/or electric lighting?
 
I guess there is no over sampling on an rtrace calculation, but for an irradiance calculation image, my -ad setting is usually in the thousands and my ambient bounces are at 4 or so (depending on the results of a parameter test)  I'm guessing the -ab and -ad parameters can't be reduced if light level accuracy is important.  Maybe I'm wrong?  Sure would be nice to slash some of those crazy calculation times.
 
Mark
