Hey guys! Do you know the easiest way to find a path of intersect of two meshes (mesh with plane)? May I do this with babylon.js or do you know another js lib that can do this? Thank you :slight_smile: This is an example screenshot from blender app. [image]

May be I can do this with CSG? or not?

I’m not sure what you are trying to do but this might help. https://doc.babylonjs.com/babylon101/intersect_collisions_-_mesh

Hi guys. [image] avin: May be I can do this with CSG? Yeah, I was sort-of thinking in the same direction… or possibly with a shadowMap or stencilBuffer (like I know what a stencilBuffer can be used-for). hehe. Babylon.js Playground Babylon.js playground is a live editor for Ba…

[image] Wingnut: CSG thank you, than I’ll try to dig into CSG code to find answers :slight_smile:

My pleasure. hmm. In my opinion, NOW it’s time to TRY to gather all finalMesh.vertexData POSITION-KIND data (the positions of ALL the vertices of finalMesh). Gather those in a giant pile, then go thru them (iterate thru them)… and gather every position which has a Y-value that is a [range] below …

did like that :slight_smile: https://playground.babylonjs.com/#D25VJD#3 but without a valid sequence we’ve got invalid path :upside_down_face:

Ooooh, nice! You know what you are doing. I’m glad. I think you’re going to nail this. Good codin’!!! Real nice. Let’s ping-in @jerome and @JohnK … see if those path-masters have some advice.

Hi there! I am looking exactly for same outcome - intersection path around 3D object (I would like to draw this intersection path on one axis). I looked at numerous examples, tried BB intersections, CSG, … with no reasonable success and I believe this is the best idea so far. Do you have maybe fin…

I’m suffering in this problem, can you share your solution with getClosestFacetAtCoordinates? appreciate for you :slight_smile:

seems like I can solve this problem with Use Facet Data - Babylon.js Documentation and getClosestFacetAtCoordinates. I can move in cut plane and collect points from the surface of the mesh into an array in correct order.
