The trouble is that Windows doesn't support command-output-as-parameter, so just run "vwrays -d -vf view1.vf -x 1024 -y 1024" on a separate command, then paste the output onto the rtrace command line.

I’m working through Axel Jacobs' excellent 'rtcontrib' tutorial and I want to generate a Radiance picture using rtrace instead of rpict. For your information, I'm under Windows 7 with the latest Radiance binaries downloaded from the NREL Openstudio website: http://openstudio.nrel.gov/getting-started-developer/getting-started-radiance
When I try this:
vwrays −ff −vf view1.vf −x 1024 −y 1024 | rtrace ‘vwrays −d −vf view1.vf −x 1024 −y 1024‘ −ffc scene.oct > view1.hdr
I obtain this error message:
rtrace: fatal - command line error at 'vwrays'
Then I use double quotes...
vwrays −ff −vf view1.vf −x 1024 −y 1024 | rtrace "vwrays −d −vf view1.vf −x 1024 −y 1024" −ffc scene.oct > view1.hdr
...and I obtain this error message:
rtrace: fatal - command line error at 'vwrays −d −vf view1.vf −x 1024 −y 1024'
Any advice on how to solve or work around this problem would be greatly appreciated !
Thanks in advance,
