Hi, there's some test:

I don't know if it's related to maxwell core or just rhinoll bug, due to SDK the rhinoll just to pass the lat/lon and date/time values to maxwell core, no precalc.

Rhino3D sr4-2, mw 1.2.1_beta, rhinoll 0.6

Hi Tom,

What software did you use for the simulation ?

Also, is it showing solar-time, or mean-solar-time ?

I've calculated azimuth/elevation of the same time as mw should calculate.. create 'sun' like emitter ball .. and tested

Hum, maybe a plugin error. Sun position is now accurate (as far as I can tell with the sundial method) with Lightwave plugin.

Cinema sun is no reference, and I don't think that the rhino sun is either. Please check any reference implentation first against real astronomical data.
