[Radiance-general] Three-Phase Method: dmx

[Greg Ward]

Hi Chantal,

Yes, you need the newer version of dctimestep.  You can find HEAD sources from the HTML interface at:

	http://www.radiance-online.org/cgi-bin/viewcvs.cgi/ray/src/#dirlist

Getting to the appropriate "Download" link you find:

Best,
-Greg

> Usage:dctimestep DCspec [ skyvec ] 
> dctimestep Vspec Tbsdf.xml Dmat.dat [ skyvec ]

> I sounds to me that is not accepting the -n, so I guess that there might be a new version that it takes it.

>> Dear Radiance List
>> 
>> I'm coming with another question that is probably too simple but still keeps me from moving to the next phase of  the 3Phase:
>> 
>> When I create the daylight matrix using genklemsamp & rtcontrib I obtain a file with only the header and sometimes some weird symbols ike : ½7†7½7†7½7†7
>>  
>>  If I use such file (*.dmx) with dctimestep I get the following Error messages :
>>  warning - unexpected data at the end of binary file results/window_SOUTH.dmx
>>  
>>  or
>>  fatal - unexpected EOS reading results/window_SOUTH.dmx
>>  
>>  my commands are just like in the Exercise 2 of the tutorial:
>>  genklemsamp -vd 0 -1 0 objects/window_S.rad | rtcontrib -c 1000 -e MF:4 -f reinhart.cal -b rbin -bn Nrbins -m sky_glow -faf model_dmx.oct > results/south.dmx
>> 
>> If I try to do the same in Windows I get:
>> 
>> Usage: vwright {offset|name}
>> Argument "" isn't numeric in multiplication (*) at genklemsamp.pl line 51
>> Argument "" isn't numeric in multiplication (*) at genklemsamp.pl line 51
>> Illegal division by zero at genklemsamp.pl line 51.
>> 
>>  I'll really appreciate your help! 
>> 
>> Thanks in advance!
