The supplied ordinates are interpreted as a sequence of points, which generates a convex hull in the source space. The returned sequence of ordinates represents a convex hull in the output space. The number of output points will often be different from the number of input points. Each of the input points should be inside the valid domain (this can be checked by testing the points' domain flags individually). However, the convex hull of the input points may go outside the valid domain. The returned convex hull should contain the transformed image of the intersection of the source convex hull and the source domain.
A convex hull is a shape in a coordinate system, where if two positions A and B are inside the shape, then all positions in the straight line between A and B are also inside the shape. So in 3D a cube and a sphere are both convex hulls. Other less obvious examples of convex hulls are straight lines, and single points. (A single point is a convex hull, because the positions A and B must both be the same - i.e. the point itself. So the straight line between A and B has zero length.)
Some examples of shapes that are NOT convex hulls are donuts, and horseshoes.
