Thank you very much for your answer Andrew.
Can you explain me more in detail about the required "conversion" for BSDF xml ?
Thank you

Subject: Re: [Radiance-general] Three-phase Method dctimestep
When dctimestep reads the BSDF xml, there is a conversion required for it to be a true coefficient matrix. If you're giving it a BSDF, I suspect this might be one of the causes of the discrepency you're observing.

Jinsook, DCTIMESTEP does multiply matrices, a pretty naive method, actually. I have no idea what might be causing the dismatch between your results and DCTIMESTEP's.
Nothing too helpful... sorry. Bye!

Hi everyone.
Is there anybody who knows how dctimestep works in three phase method?
When I tried to multiply as a normal matrix (with python language), the illuminance result is not matched with dctimestep result.
So, I wonder if dctimestep doesn't use normal matrix multiplication.
If there is a specific method in dctimestep, please teach me.
* let you know,
1. I picked up one column out of the every RGB(view matrix and daylight matrix), so that I made a simple matrix multiplication.
2. I created daylight matrix as a ASCII data instead of binary.
Thank you.
Jinsook
