convert object’s 3D position to camera’s perceived 2d XY position on screen?
I’m sure this topic has probably been covered, but I can’t seem to get the search engine to spit out any previous discussions or tuts. A link would be fine, thanks.
Anyway, I’d like to apply a global 2D distortion effect’s XY centerpoint to the apparent XY position of an on-screen 3D object. How do I convert it’s known 3D pos into the apparent screen position in XY?
Thanks,

After doing a bit more digging, I found this post by Dan E.
Works like a charm. Dan, when is your book coming to Barnes & Noble?! 🙂https://forums.creativecow.net/readpost/2/521802?&archive=T
in short, here’s the code:
L = this_comp.layer(“NullrotateElements”);// link to the layer you want to track
L.to_comp([0,0]) // offset as neededAntifreeze Design
