[Radiance-general] Divide by zero with colorpict

[Kirk Thibault]

Tarik

One thing I noticed when I did that exercise is that Debevec's world in 
<angmap.cal> is Y up and Radiance defaults to Z up.

I have no idea if this is a problem from the standpoint of generating 
the errors below, but it is something that I noticed.

I have gotten multiple "divide by zero" messages from rpict when using 
IBL as well.  It just keeps on chugging through the calcs though.  
Greg?

Here is a link to my Radiance-IBL tests with the Debevec scene and some 
of my homegrown HDR's (thanks to Debevec's HDR shop and Greg's 
Photosphere).

good luck
