and yeah you can still put not-IMAX format on the fuckhuge screen but then what's the point, might as well just use a normal 16:9 texture like the 200 media worlds that are already out there

ok here's a fun #geometry problem:

i am told #IMAX screens are curved such that every point on the screen is the same dist from the projector lens (~ a point). this would make the screen a spherical quadrilateral. (not 100% on this, some images seem to depict the screens as cylindrical. correct me if i'm wrong!)
however, i don't know this distance.
instead, what i have are two flat numbers, e.g. "29.8m by 32m". these numbers produce an aspect ratio of eg ~1.29, not IMAX's spec of 1.43. so these numbers are probably along the curved surface and not linear point2point.

Q1: Assume the distances are along the curved surface. How do I compute aspect ratio to double-check this assumption?

Q2: How do I find the radius of the sphere the screen sits on given these measurements?

The end goal here is to accurately model the screen's surface in Blender or maybe straight up CAD (something something Autodesk, I guess).

I am not totally confident that Q1 is well-formed here, by the way.

oh btw looks like there's fan edits of the Nolan Batman films that splice in the IMAX scenes. apparently those are in the disc just not the main movie so someone managed to edit it all together.
