How do you convert 3D coordinates to 2D/UV coordinates?

I got a little bit closer

I got this by adding the two divide by 10 nodes…

But I have basically no idea what I’m doing lol.

Edit: I just realized I saw the other day some chart with some numbers for that bottom Z multiply math; this is to account for the perspective, i think these numbers if i recall correctly are for ‘perspective’ but maybe they need to be ‘ortho’ cuz the uv unwrap was done with an ortho scene capture camera? :thinking: but i forgot where I saw those numbers so I don’t know what numbers to try :man_facepalming:

The 57.3 is something to do with FOV, it happens to be the exact same number as another number used in a convert fov to angle in degrees node…
