Mesh Intersection Event

This is similar to a question I had about collisions. I know the mesh intersect can be used for “triggers”, where I can detect a mesh entering another mesh. The playground examples from the docs here: Mesh Intersections | Babylon.js Documentation uses


This works, but it also seems excessive if I just wanted to check an initial intersection. Is there a more efficient way to detect this intersection without having to check every frame? I suppose this is more of a general question about detecting one-off events like this.

You have to check it on every frame until you found it. Then you can simply unregister your function to avoid additional unnecessary checks


Thank you, I’ll do that.
