<p>Mesh weld tolerance. If mesh welding is enabled, this controls the distance at which vertices are welded. 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 clean. If not, a warning will be emitted. Having a clean, welded mesh is required to achieve the best possible performance. </p>
<p>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.</p>
<p>The mesh validation approach also uses the same snap-to-grid approach to identify nearby vertices. If more than one vertex snaps to a given grid coordinate, we ensure that the distance between the vertices is at least meshWeldTolerance. If this is not the case, a warning is emitted.</p>

<p>If 0.0f is set all points are accepted when the convex hull is created.
