[Radiance-general] physically-based landscapes

[Carsten Bauer]

Hi Rob,
just one further remark: self-evidently, you have to be shure that the part of 
the hemisphere visible form the window of your scene is completely covered by 
the image/light maps. So rendering a fisheye view of the outside landscape 
and mapping this on a sphere is the preferrable way. Look throug the lib 
directory, I think there (or in one of the contributions availabel on the 
radsite) is a .cal file included which does this spherical mapping.
