Penetrating mesh

[oschakravarthi]

Hi,

I am trying to put a hole  in mesh2 as if another mesh mesh1 has fall down on mesh2 and penetrated it as shown in the attached picture.

 

Thanks in advance.

@trevordev, Can you please help me?

csg should work for this: https://playground.babylonjs.com/#T6NP3F#0

Yes. I have checked this. but I could not implement things like,

1. determine the position of mesh1 if it fell down on mesh2.

2. the thickness of mesh2 so that I can put a hole all thru its height.

Im not sure Im understanding, the position of it falling would just be equal to when its y value is the same as the mesh2? What do you mean thickness, with csg you can just put the object inside the other object and then cut it out.

Are you trying to do this in realtime? The performance of csg is not really suited for that

Hi @trevordev

atleast, how can I do this?

var floorCSG = BABYLON.CSG.FromMesh(floorMesh);

 var boundingInfo = new BABYLON.BoundingInfo(someMin, someMax);

var boundingBox = boundingInfo.boundingBox;

floorCSG.subtractInPlace(boundingBox); ///How can I do this last step?

Create a box with the proportion of your bounding info. and then substract but as @trevordev said, this is not really suitable for real time usage if you need to do it often.
