At the point {X: -0.8164382918936324, Y: 2.542909114087213, Z: 5.006102143191411}, the SDF value for the teapot model is returned as a positive number. It means the point is outside the teapot. But we are sure that the point is definitely inside the teapot.

The approximate coordinates for the neighbor points around the problematic {X: -0.8164382918936324, Y: 2.542909114087213, Z: 5.006102143191411} point are shown below. They all have negative SDF values, that is expected.
