Projection of images onto a curved surface

Good morning forum staff

I would like to thank you for all the help I have receinved from you and I am grateful for the time you have spent in resolving my problem.

I have a tunnel surface that contains small áreas that have been intentionally cut out. I want to project images into these areas. But when I look at them from inside the tunnel, they are bigger than the small areas, they are upside down or facing outwards. How do I fix these errors in projected images?

Thank you very much, I appreciate all the help.

Good afternoon Li
the surfaces are trimmed, yes, but if this is a problem, how do I overcome this, I’m new to grashopper and I don’t know how to project the images, where looking from inside the tunnel, they are in the right position. I am grateful for all the help you can give me.
