<p>Plane shifting is an alternative algorithm for the case when the computed hull has more vertices than the specified vertex limit.</p>
<p>The default algorithm computes the full hull, and an OBB around the input vertices. This OBB is then sliced with the hull planes until the vertex limit is reached.The default algorithm requires the vertex limit to be set to at least 8, and typically produces results that are much better quality than are produced by plane shifting.</p>
<p>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 very far away from the input cloud, and does not guarantee that all input vertices are inside the resulting hull.However, it can be used with a vertex limit as low as 4. </p>
