It is easy to compute the convex hull in geometry nodes. It would be very helpful for me to find out, whether a random point is located inside the convex hull. My nodes setup is displayed in the image.Can this be easily achieved with geometry-nodes? The only possibility that comes to my mind, would be checking each point against every face.

enter image description here

The solution works for a lot of points but there are errors. I think, I'm not sureI know why.The point can be closer to a small face on the back of the convex hull, than to a large face on the front side. To be on the save side, this test would have to be done for every face of the convex hull.
