[Radiance-general] problems creating animation viewfile

[Jack de Valpine]

Hi Tarik,

The problem is that keys.cal is not being completely generated. I think 
that there are a couple of things to look at.

First, I do not think that you are doing quite the right thing to create 
key.fmt. "key.fmt" should be a file that contains a format, in this case:

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}

This should all be on one line and should not contain trailing or 
leading white spaces. This is the string that rcalc will match to in 
order to extract your variables.

As far as I can tell, I do not think that this is a valid command:

./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} > key.fmt

Second, I believe that there may be a problem with the case of the 
variable names used. For example, your key.fmt uses all lower case (such 
as px, py and pz). Whereas in the call to tabfunc and the second call to 
rcalc you use mixed case for the variable names such as (Px, Py and Pz). 
I am not sure what os you are running on, it is possible that cygwin 
ignores case and quite likely that windows does. Unix/Linux/OsX however 
do expect case to match.
