by plane shifting.
When plane shifting is enabled, the hull computation stops when vertex limit is reached. The hull planes
are then shifted to contain all input vertices, and the new plane intersection points are then used to
generate the final hull with the given vertex limit.Plane shifting may produce sharp edges to vertices

If mesh welding is not enabled, this value defines the acceptance distance for mesh validation. Provided no two vertices are within this distance, the mesh is considered to be

The default vertex welding uses a snap-to-grid approach. This approach effectively truncates each vertex to integer values using meshWeldTolerance.
Once these snapped vertices are produced, all vertices that snap to a given vertex on the grid are remapped to reference a single vertex. Following this,
all triangles' indices are remapped to reference this subset of clean vertices. It should be noted that the vertices that we do not alter the
position of the vertices; the snap-to-grid is only performed to identify nearby vertices.
