Typically when creating irradiance images for falsecolor plots I set up
two views in the rif file:
view= Plan -vf views/Plan.vf
view= Plan-i -vf views/Plan.vf -i
When rendering in rad via rad -N 8 studio1.rif the two images render as
radiance. The output from the rad command:
rad -N 8 studio1.rif

When rendering without the -N option in rad or (TRAD default behaviour -
yet to figured out how to specify the -N option for trad) the output is
the expected radiance and irradiance images. The output from the rad
command:
rad studio1.rif

Version Head 2010-05-24
on Mac OSX 10.6.3
Notes:
1) For the compile the head didn't include the tiff source yet the
makeall still required it (copied the src/px/tiff folder from an earlier
download and recompiled).
2) To make trad run under OSX:
mv ray/bin/trad ray/bin/trad-original
new file ray/bin/trad
#!/bin/bash
exec wish /path_to_ray_folder/bin/trad-original "$@"
Any ideas or have I misunderstood the usage of the -N option in rad.
