[Radiance-general] Lighting from a light probe

[Greg Ward]

There's something I'm not getting, here.  Why would you synthesize a 
light probe?  The whole point is to use a captured environment, isn't 
it?  If you had a good synthetic environment, you would just render 
your synthetic object(s) into it directly.  Or are you doing this as a 
test?  I would be surprised if HDRShop paid attention to the Radiance 
view parameters in the .pic file, as it's not expecting to read a 
Radiance rendering as a light probe.

By the way, there are two types of spherical projections used in 
HDRShop -- an angular projection and a spherical projection.  They are 
subtly different.
