ConvexHull* Geo::ConvexHullBuilder::BuildConvexHull
...
public: ConvexHull * BuildConvexHull()
...
Build a convex hull.
Not const because it does internal sorting.

bool Geo::ConvexHullBuilder::BuildConvexHull
...
public: bool BuildConvexHull
(
ConvexHull * hull,
Geo::s32 * numPoints
)
...
Build a convex hull.
Not const because it does internal sorting. This does the operation in place and returns the actual number of points on the hull. Use this if you are creating many hulls and don't want to allocate new hulls each time.
