[Concept]Colour Face by Sun Orientation?

[ivreich]

Hi

Is there an existing plugin that allows faces to be coloured or selected according to their angular relationship to the sun at any given time of the day?

This could allow me to select all the faces that are close to perpendicular to the sun angle at 9am, 12 noon, 3pm etc. Could be useful for mapping the path of the sun across a facade, so that different shapes/sizes of sun shading can be mapped onto relevant faces.

Any thoughts?

It's not quite what you want but Jim made a plugin to attach the camera to the sun so you can track the sun on your structure. Might help.

Not quite the same I think...there's another plugin called Shadowtex (by Renderiza) that does something quite close by tracing a line from the center of every face to the sun's current position, but it uses this information to detect faces that are in shadow.

Maybe this technique can be modified to detect angles between faces and the sun angle? I know nothing about rubyscript, so unfortunately I wouldn't even know how to begin trying to build something like this...maybe one of the gurus here can have a think about it.
