[Radiance-general] gendaymtx axis convention and -O 1 option.

[Germán Molina Larrain]

Dear list,

I was trying gendaymtx and the new dctimestep (it works excelent, thanks to
the developers), and noticed the following.

I modeled a big cube, and set sensors pointing north, south, east and west
(the idea is that the cubes shades). Then, I made a DC matrix, created the
sky matrix; and dctimesteped all together (the weather used is Montreal),
and got THESE <https://sites.google.com/site/sunliteproject/comments>
 results.

The sensors were defined (North, South, East and West, respectively)

0 3.1 1 0 1 0
0 -3.1 1 0 -1 0
3.1 0 1 1 0 0
-3.1 0 1 -1 0 0

Anyway; North and South seem to be ok to me (simetric along the day, and
the south has more "sun" than north). But West and East seem to be
inverted...? and the east is more insolated in the afternoon? (I havent
really looked at the numbers themselves, but just to the tendency). *Can
there be a bug in the program??*

On the other hand... is there any plan on adding the -O option to
gendaymtx, to get the solar intensities?

THANKS TO EVERYONE IN ADVANCE

German
