xform -e

Hi all!!

Does anybody know what '-e' in xform's parameters, mean?

I'm not able to find it out.. and it is used in Rendering with Radiance Chapter 7.

And xform doesn't report any problem using it, so it should mean something..

If it is written somewhere what -e means, please, say it to me, it could be that I'm missing some reference..

Thanks in advance for any reply.

Hi Lucio,

Does anybody know what '-e' in xform's parameters, mean?

It is the opposite of -c.

If you put something like:

!genbox white box 1 1 1

into a .rad file, then xform with the -c option
does not expand it, writing

!genbox white box 1 1 1 | xform -e

to the output.

With the -e option xform does expand the
external generator command in the file
into the actual geometry,
with all the polygon primitives.

Ciao,

F.

Thank you very much for such fast reply !!!

So it is completely superfluos, 'couse it is default option.. isn't it?

Yes, it is superfluous -- you are correct. It didn't used to be the default, so I left the option in there for backwards compatibility. The -c option was added when -e was made the default, many years ago.
