Functions

WlzVertexP WlzVerticesFromObj (WlzObject *obj, WlzVertexP *dstNr, int *dstCnt, WlzVertexType *dstType, WlzErrorNum *dstErr)
 Allocates a buffer which it fills with the vertices from the given object. If the object is not one of the types that is represented by vertices, eg polylines, boundlists, contours ..., then this may result in a very large number of vertices, with for example one per voxel. Normals will only be allocated and set for objects represented by vertices, eg there will be no normals for voxel based objects. More...
 
WlzVertexP WlzVerticesFromObjBnd (WlzObject *obj, int *dstCnt, WlzVertexType *dstType, WlzErrorNum *dstErr)
 Extracts all vertices that lie on the boundary of the given objects domain. More...
 
WlzErrorNum WlzVerticesFromObjBnd2I (WlzObject *obj, int *dstNVtx, WlzIVertex2 **dstVtx)
 Extracts all vertices that lie on the boundary of the given 2D domain object's domain. More...
 
WlzErrorNum WlzVerticesFromObjBnd3I (WlzObject *obj, int *dstNVtx, WlzIVertex3 **dstVtx)
 Extracts all vertices that lie on the boundary of the given 3D domain object's domain. More...
 
WlzErrorNum WlzVerticesFromObj2I (WlzObject *obj, int *dstNVtx, WlzIVertex2 **dstVtx)
 Extracts all vertices that lie within the given 2D domain object's domain. More...
 
WlzErrorNum WlzVerticesFromObj3I (WlzObject *obj, int *dstNVtx, WlzIVertex3 **dstVtx)
 Extracts all vertices that lie within the given 3D domain object's domain. More...
 
WlzVertexP WlzVerticesFromGM (WlzGMModel *model, WlzVertexP *dstNr, int **dstVId, int *dstCnt, WlzVertexType *dstType, WlzErrorNum *dstErr)
 Allocates a buffer which it fills with the vertices from a geometric model. More...
 
WlzVertexP WlzDVerticesFromGM (WlzGMModel *model, int *dstCnt, WlzVertexType *dstType, WlzErrorNum *dstErr)
 Allocates a buffer which it fills with either 2D or 3D double precission vertices from the geometric model. The indicies of the vertices in the buffer are the same as the indices of the vertices in the model. More...
 
size_t WlzVertexSize (WlzVertexType type, WlzErrorNum *dstErr)
 Returns the size of the given vertex type. More...
 
int WlzVertexDim (WlzVertexType type, WlzErrorNum *dstErr)
 Returns the dimension of the given vertex type. More...
 
WlzVertexP WlzDVerticesFromCMesh (WlzCMeshP mesh, int *dstCnt, WlzVertexType *dstType, int skip, WlzErrorNum *dstErr)
 Allocates a buffer which it fills with either 2D or 3D double precission vertices from the conforming mesh. The indicies of the vertices in the buffer are the same as the indices of the vertices in the model unless the skip non-valid nodes flag is set.. More...
 
int WlzVertexQSortFnI2 (void *p0, void *p1)
 Function for AlgSort() to sort WlzIVertex2 vertices so that they have increasing Y then X. More...
 
int WlzVertexQSortFnI3 (void *p0, void *p1)

int WlzVertexHeapSortIdxFnI3 (void *data, int *idx, int id0, int id1)
 Function for AlgHeapSortIdx() to sort WlzIVertex3 vertices so that they have increasing Z then Y then X. More...
 
int WlzVertexHeapSortIdxFnD2 (void *data, int *idx, int id0, int id1)

int WlzVertexHeapSortIdxFnD3 (void *data, int *idx, int id0, int id1)
 Function for AlgHeapSortIdx() to sort WlzDVertex3 vertices so that they have increasing Z then Y then X. More...
 
AlcKDTTreeWlzVerticesBuildTree (WlzVertexType vType, int nV, WlzVertexP vtx, int *shfBuf, WlzErrorNum *dstErr)
 Allocates and populates a k-D tree from the given vertices. The vertices are either WlzDVertex2 orWlzDVertex3. More...
