Honeybee transferring field-points in light direction

Hey there!

I have a question concerning honeybee. I hope someone has an idea or can give me a hint. At the moment I’m working on the idea for a parametric facade while using honeybee data to provide a field on which the facade will be generated (with Wasp). I’m able to get points with values inside a room. The problem is I would need those points and values at the point of entrance into the room (windows) to be able to run Wasp to generate the facade. Is it possible to get certain values on the way between the light source and when it hits the ground inside the room?
I hope the attached picture explains it a little bit better. The Grasshopper file is also attached.honeybee_daylight.gh (507.2 KB)
