The model shots as CGI reminds me of RoboCop's "thermal vision". Renting an actual heat sensing camera was too expensive, so they just filmed people in black spandex covered in fluorescent paints under a black light.
It's so close to holding up though. If they had blurred it a smidge so you don't see the folds in the spandex it'd be perfectly fine. Thermal cameras aren't known for their high resolution anyway.
It's clever, but I don't think it really holds up: https://youtu.be/Md14H_qD8iQ
I always thought that shot looked weird, but I never questioned the wireframes in Escape From New York.
