Detailed Description

3d convex hull defined by an explicit collection of points called vertices. Note: vertices need not be extreme points WARNING: Points are referenced not stored for optimal performance in' some applications. The list of points must remain alive and in there initial location For the duration of this object.

This is an improved version of ON_ConvexHullRef that includes support for 2d point lists.
