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... | |
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... | |
