Variable height shading systems simulation

Hi guys

I'm trying to do a all year simulation with a roller shade only covering
half my window.

I've been trying to do it in an identical way as in Andy's example two of
the three fase method, i divided my window in two different polygons, one
for the shaded part and one for the unshaded part, created a view matrix
and daylight matrix for both parts of the window, and now i'm trying to use
the "rlam" command to put it all together in a single illuminance file. The
problem is the file that is coming out of "rlam" doesn't look good, it has
to much rows, and when i try to run "rmtxop" to convert RGB values to
illuminance values i get the fallowing error:

rmtxop: operation failed on 'results/illuminance_RGB/closed_50.dat'

Any hint on how to solve this, or a more efective way to do it?

Best regards
Humberto A.

Hi Humberto,
There's an easier way to do this now. No need to use rlam anymore.

First create your partial illuminance files:
rmtxop -c upper.vmx window.xml upper.dmx sky.smx | rmtxop -c 47.4 119.9
11.6 > upper_illum.mtx
rmtxop -c lower.vmx window.xml lower.dmx sky.smx | rmtxop -c 47.4 119.9
11.6 > lower_illum.mtx

Then add them together:
rmtxop upper_illum.mtx + lower_illum.mtx > total_illum.mtx

Hi Humberto,

Although your description of what you are trying to do isn't bad, we really need to see the commands you are using to be of assistance. In general, a list of commands, and your exact error message are needed. It also helps if you can make your source files available somewhere, though these may not be needed.

Cheers,
-Greg

OOPS! Omit the -c in the beginning of the first rmtxop commands! My bad.
