Multi-picking all intersected faces?

Recommended Posts

Hey there,

I'm looking for a way to find all the intersections of a ray passing through a scene: an extension of multi-pick, but capturing multiple face intersections for convex (or non-planar) objects. That means front face, back face, and potentially others.

Why?  I'd like to simulate a core sample of a scene by collecting front and back faces along a ray, sorting them, and figuring out the inside/outside relationships.

Is there any reasonable way to reuse the Babylon.js picking machinery to do this?
