If you’re using vtk.wasm, you can try vtkCollisionDetectionFilter

Live example: https://vtk.org/files/examples/CollisionDetection/index.html

Without using vtk.wasm, is there any feature like that in vtk.js
Or can we try any other approach for that, if possible can you please suggest me that method.
