If this question cannot be answered or from what i've heard isn't true, then you can ignore this post.
So I heard it was possible to calculate curved surfaces like curtains to still be able to project a straight line, or non distorted looking laser graphics.
Is this really possible???
if yes how, and how do they do it.... what do they use?
I'm not sure if I should post this in "advanced" technical discussion.
But I rather just want to know because I'm curious
Cheers,
