[Radiance-general] One question on colordata

[Greg Ward]

Hi Simin,

The color won't be different if all three of your data files are the same.  You could just use brightdata in that case.  Without knowing what is in "rang.cal", it's difficult to even guess what this will do.

The real parameters to colordata are optional, and used by your .cal file for whatever purpose suits you.
