[Radiance-general] Generate a Radiance picture using rtrace instead of rpict under Windows

[François Cantin]

Hi,

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,


François Cantin
