Pass diagrams that match the perspective of a football pitch

Question

Hi everyone,

I want to illustrate football passes on top of a photo (or a still frame from a video) of a football pitch in After Effects. The problem is that the pitch is not flat, it’s in perspective (shot from the stands).

I already know how to draw and animâtes passes (lines or arrows) but I want them look like they are lying on the ground of the pitch and make sure they respect the 3D perspective (not just flat shapes).

I tried using 3D orientation and also Corner Pin, but I can’t make it look right.

What’s the simplest way to make my passes follow the perspective of the field?

Thanks a lot for your help!

Sounds like you want a 3D shape that can be angled but remains 3D rather than 2D stretched. There's a couple of techniques you could use:

CC Particle World with velocity and gravity set to 0 and the producer radiuses also 0. You can use that to draw lines in 3D space. Much easier if you attach the producer to a null too ( https://www.youtube.com/watch?v=dYYmeBOWXpw )
Shape lines linked to 3D points. i made a tutorial recently showing how to add 3D travel lines to a world map. I think this might help: https://www.youtube.com/watch?v=eQLN3WVhKVs
