Point Clouds

For a surface or 3D object, all of the points lie on the surface itself; the points define the surface. But a point cloud is a distribution of points with no defined surface. The convex hull algorithm built into ViXL-3D attempts to define a shape for the volume populated by the point cloud, using the point distribution as the basis for determining the hull boundary.
