– convexHullPoints:count:
Access the plane’s convex hull data.
Always check pointsCount after the method returned. In case it is 0, the array pointer pointer was not assigned to any data.
The data pointed to by pointsArray is valid for the lifetime of the WTPlane object that returned it.
- (void)convexHullPoints:(const simd_packed_float2 *_Nullable *_Nullable)pointsArray count:(NSUInteger *)pointsCount
Parameters
pointsArray |
A pointer to a simd_packed_float2 array that will contain the points of the convex hull after the method returned. |
---|---|
pointsCount |
A pointer to a NSUInteger that will contain the number of points in the convex hull after the method returned. |
Declared In
WTPlane.h
– requestConvexHull:
Requests the plane’s convex hull from the data provider. (Deprecated: use -convexHullPoints:count: instead.)
- (void)requestConvexHull:(WTConvexPlaneHullDataProvider *)dataProvider
Parameters
dataProvider |
The object that determines and provides the convex plane hull’s data. |
