## Description ### Functions and Procedures
`function ConvexHull(Points: TVector3SingleList): TIntegerList;`
Calculates `ConvexHull` ignoring Z coordinates of pixels. That is, all Points[*][2] are ignored. Returns newly created array with the indices to Points. If you want to draw an edge of convex hull, you want to iterate over these points like (for each i) Points[Result[i]]). Points.Count must be >= 1.
