Functions

WlzConvHullDomain2WlzMakeConvexHullDomain2 (int maxVtx, WlzVertexType vtxType, WlzErrorNum *dstErr)
 Allocates a new 2D convex hull domain with space for at least the requested number of vertices. More...
 
WlzConvHullDomain3WlzMakeConvexHullDomain3 (int maxVtx, int maxFce, WlzVertexType vtxType, WlzErrorNum *dstErr)
 Allocates a new 3D convex hull domain with space for at least the requested number of vertices and faces. More...
 
WlzErrorNum WlzFreeConvexHullDomain2 (WlzConvHullDomain2 *cvh)
 Frees the given 2D convex hull domain. More...
 
WlzErrorNum WlzFreeConvexHullDomain3 (WlzConvHullDomain3 *cvh)
 Frees the given 3D convex hull domain. More...
 
WlzConvHullDomain2WlzConvexHullCopy2 (WlzConvHullDomain2 *gCVH, WlzVertexType rVtxType, WlzErrorNum *dstErr)
 Copies the given 2D convex hull domain which has the minimum required number of vertices, with verticies of the required type. More...
 
WlzConvHullDomain3WlzConvexHullCopy3 (WlzConvHullDomain3 *gCVH, WlzVertexType rVtxType, WlzErrorNum *dstErr)
 Copies the given 3D convex hull domain which has the minimum required number of vertices and faces, with verticies of the required type. More...
 
WlzObjectWlzConvexHullToObj (WlzObject *cObj, WlzObjectType rType, WlzErrorNum *dstErr)
 Computes a new object of the requested type enclosing the same region of space as the given convex hull object. More...
 
WlzObjectWlzObjToConvexHull (WlzObject *gObj, WlzErrorNum *dstErr)
 Computes the convex hull of the given object. If a degenerate convex hull is returned then the returned error will be WLZ_ERR_DEGENERATE. More...
 
WlzObjectWlzObjToConvexPolygon (WlzObject *obj, WlzErrorNum *dstErr)
 Construct the minimal convex polygonal cover from interval domain. More...
 
WlzIVertex2 WlzConvexHullVtxD2ToI2 (WlzDVertex2 d, WlzDVertex2 c)
 Convert the given double vertex to an integer vertex such that it will enclose the given convex hull double vertex. More...
 
WlzIVertex3 WlzConvexHullVtxD3ToI3 (WlzDVertex3 d, WlzDVertex3 c)
 Convert the given double vertex to an integer vertex such that it will enclose the given convex hull double vertex. More...
