Math - Blinds position calculation

[Thomas]

Hello


I'm looking for mathematic formula for calculating of position of blinds.
The idea is: I know azimuth and horizon of sun position.
I know position of my window and position of my desk in the room.
The requirement is: I want natural light but sun must not shine directly to my table.
I tried it but the calculation looks so complex.

Don't you have already done solution for this request?
Thank you

Unfortunately it's a different topic. I don't believe the only one message touching this topic suggesting "Use just elevation" works. Especially in summer and winter season there must be a big difference in azimuths.
