[Radiance-general] proposed feature: interpreting view names in rad

Yes, I have used it for all kind of stuff before. But in my case, I
would have to add configuration files for ranimate additionally to the
rif. And all I want to do is rendering three groups of views. I know
that there are work-arounds, but I cannot imagine any case where one
would need the current behaviour of rad to render only the first view of
a viewfile, as in that case one would not have added other views to the
same file (or had commented them out.

Regarding the idea, that there should always be only one view per view
file, this is a contradiction to the behaviour of core radiance tools.
rvu e.g. appends views to an existing view file, and I can cat a view
file with hundreds of views into rpict, which will happily render one by
one. I cannot use these view-files only in rad, as (only) this tool
reads only the last line of a view file.

At the moment I am using a "<myview.vf" at the end of the render= line
in my rif file. This is a work-around, but not a nice one, as it
disables filtering and naming.

BTW, we should also change the default extension for filtered frames to
hdr in rad, now that there is a mime-type registred.

Cheers, Lars.
