Projecting image onto planar surface to obtain printable decals

Hi all,

We have made a pavilion:

For another event we want to put some stickers on the pavilion, to show an image which can be seen from a certain point.

My question is:

How can I use grasshopper to project an image onto a planar surface and the export this projected image as a png, jpg or some other image file?

Hope you can help. :)

Timo

To answer your second question first: I looked at doing a "batch" print back in the day but it didn't seem readily done. Your pavilion doesn't look like it has an insane number of faces so (worse comes to worse) you could manually print each face.

Thinking about first question... spherical-type texture mapping is what comes to mind. Human add-on might (approximately) do the trick.

Thinking further, you'll have to provide more detail on the specific setup of the projection (and outcome) you're hoping to achieve. A diagram or illustration would be helpful.

Not sure exactly what I'm doing since I don't know anything about texture mapping, but having fun with a cylindrical mapping on a hemisphere... Kinda works.
