I don’t even know if this is possible, but I would like to make a lamp for my wife that projects a text on the ceiling. The attached picture is not the text I want, I took something simple for modeling.
The sides of the lamp are at 45° to the ceiling.
I am wondering how I could calculate how to shape the text and cut the lamp side so that the texts appears as clean as possible on the ceiling, by that I mean not deformed on the ceiling.
I don’t know if that is clear or not. Let’s phrase it differently: how could I shape the letters on the lamp to make sure the light will project the text and look “normal” on the ceiling?
Here is an example of a lamp: Hangin%20Love%20Lamp|690x340
I assume it will never be perfect but how can I compensate light diffraction on the ceiling?
Hope that is clear enough ^^
Thanks in advance for any leads!
