[Radiance-dev] Mark Stock's benchmark on native Windows Radiance (time command)
There is a 'time' command in Windows! No need to install anything! See: http://en.wikipedia.org/wiki/TIME_(command) There even is a nice time bat-file on Stackoverflow: http://stackoverflow.com/questions/673523/how-to-measure-execution-time-of-command-in-windows-command-line To run Mark Stock benchmark on windows you have to: Step 1: copy xform.exe and rename it cat.exe OR install Mingw which seems to contain a cat.exe Step2: create a file called 'options' in the bench4 directory with this contents: -pa 1.0 -pj 0.02 -ps 1 -w+ -i- -bv+ -dt 0.050 -dc 0.50 -dj 0.0 -ds 0.250 -dr 1 -dp 512 -dv+ -st 0.150 -ab 4 -ar 128 -ad 1500 -as 500 -aa 0.15 -av 0.0 0.0 0.0 -aw 0 -lw 0.004 -ss 1.0 -lr -10 -u- -pd 0.0 Step3: Create a .bat file with this contents: @echo off echo %time% obj2mesh -n 15 -r 16384 lens.obj > lens.msh oconv -f -n 6 -r 16384 materials.rad cube2f.rad > cube2f_instance.oct oconv -f -n 6 -r 16384 materials.rad cube4f.rad > cube4f_instance.oct oconv -n 6 -r 16384 materials.rad scene.rad > scene.oct rpict @viewpoint @options -x 2048 -y 2048 -t 60 -o windows.unf scene.oct pfilt -1 -e +0 -x /4 -y /4 -r .6 -m .15 windows.unf > windows.pic ra_bmp windows.pic > windows.bmp echo %time% pause Step 4: Run the .bat file If you don't want to calculate the time yourself you can use the .bat file on Stackoverflow (I haven't tried it yet). -I believe Greg also mentioned a way to avoid the use of cat in Radiance, but I didn't understood how. :) I guess that was all I had to change.

Measure-Command in PowerShell would be a much better solution -> http://technet.microsoft.com/en-us/library/ee176899.aspx I was planning on making the necessary tweaks to Mark's benchmarks so they run on Windows via PowerShell but alas I never have any time for anything interesting.

Redirecting the input works better on both Windows and Unix than cat, to my
earlier point.

boy, was that last remark off-target.
I don't understand how that code can work? Does something in that
implementation of "system" convert slashes to backslashes?
Anyhow, in this case, could one just perhaps divert rtrace's input?
system("rtrace #{rtrace_args} < ./numeric/#{space_name}.map")
Or would that fail?

I favor "xform" with no options for this job; if the system has Radiance, I expect it will have "xform", regardless of what other commands are or are not available. But, YMMV.

Re: [Radiance-dev] Mark Stock's benchmark on native Windows Radiance
Mark, I've seen lots of people use it, probably because it fits what people expect to see in an inline command more than the stdin redirection. I think there are even some examples in "Rendering with Radiance" using it, so you're in good company...

Re: [Radiance-dev] Mark Stock's benchmark on native Windows Radiance
I am silly. This vestigial code is still in OpenStudio, for "Radiance Classic"
calcs with a continuous sky:
catCommand = "cat"
if /mswin/.match(RUBY_PLATFORM) or /mingw/.match(RUBY_PLATFORM)
catCommand = "type"
end
system("#{catCommand} ./numeric/#{space_name}.map | rtrace #{rtrace_args} …")
In this case, this really seemed to be the most direct way in. In any event,
!type would be the true one-for-one replacement for !cat when porting Mark's
scene to windoze.

Greg, Randolph, I admit that my use of "cat" is simply habit---I saw it once (probably over 15 years ago) and never let go of it. I am actually not as savvy with Unix as I am on TV. By all means make the benchmark as portable as you can and send me the changes. I will incorporate them as soon as I can. Mark On Thu, 27 Jun 2013, Gregory J.

Re: [Radiance-dev] Mark Stock's benchmark on native Windows Radiance
I am pleased to be able to say that, in fact, I ran a successful simulation. My hasty hack compilations of libtiff 3.9.7 (the last version 3 libtiff) and zlib 1.2.8 also worked, which was nice to see. Performance, well, not so good. It took 4219.9 wall clock seconds on a fairly capable Xeon, which is 1.5-2x slower than I expect based on the benchmark table. I suspect some tweaking of compilation options would considerably improve the performance, even with the relatively blah Microsoft VC10 compiler.
