[Radiance-general] Re: A question about Animations, and about the Book that will solve all my troubles...

[Greg Ward]

Hi Jeffrey,

In fact, it's not a Cygwin problem.  It's due to something missing in 
the key.fmt file.  I forgot to add the new -vo and -va view parameters 
to the list, so the format string didn't match any of the views 
produced by rview.  Here is the corrected version, which works:

rview -vtv -vp ${px} ${py} ${pz} -vd ${dx} ${dy} ${dz} -vu 0 0 1 -vh 
${vh} -vv ${vv} -vo 0 -va 0 -vs 0 -vl 0 -t ${t}

I should have checked it before reposting the message -- I had the 
chance to correct my mistake, before!

Sorry,
-Greg
