Hi Tom, I made a solution for your diagrid tower, based on the curves of the primer page 84 curves. If that is also what your mesh is based on (or somethin similar), this will work nicely.
this target list:
(a1, b1, c1, d1)
(a2, b2, c2, d2)
(a3, b3, c3, d3)
....
What I want to do is injecting one more value (arbitrary angle in my case) to each point before I cull many of them - so that each point brings its angle data along.
Any hep would be greatly appreciated. TIA

by its own tangent vector on the curve... and this happens to the last item. Here's the algorithm:
B0 ----> B1
B1 ----> B2
B2 ----> B3
B3 ----> B4

rkup) as below:
float coeff_perez [] is from Perez's paper in solar energy vol. 50, No.3. pp235-245, 1993.
i would like to adjust A3, A4, A5, A6 and A7 using measurement irradiance data over a whole year for every minute or hour, and update these coefficients under the file perezlum.cal. It means i may need to re-compile gendaylit.exe, which i have no idea how to do it.
i found radiance has another version on gendaymtx.c v2.13. it includes static const double PerezCoeff[8][20]. I am wondering which version of gendaymtx does ladybug GenCumulativeSkyMtx use.
Thanks for your suggestions on honeybee plugin. I will take a look and see how.
Cheers,
Le
