shrinkfacesPurpose2shrinkfacesReduce the size of patch facesSyntaxDescriptionshrinkfaces(p,sf)nfv = shrinkfaces(p,sf)nfv = shrinkfaces(fv,sf)shrinkfaces(p), shrinkfaces(fv)nfv = shrinkfaces(f,v,sf)[nf,nv] = shrinkfaces(...)shrinkfaces(p,sf) shrinks the area of the faces in patch p to shrink factor sf.A shrink factor of 0.6 shrinks each face to 60% of its original area. If the patchcontains shared vertices, MATLAB creates nonshared vertices beforeperforming the face-area reduction.nfv = shrinkfaces(p,sf) returns the face and vertex data in the struct nfv,but does not set the Faces and Vertices properties of patch p.nfv = shrinkfaces(fv,sf) uses the face and vertex data from the struct fv.shrinkfaces(p) and shrinkfaces(fv) (without specifying a shrink factor)assume a shrink factor of 0.3.nfv = shrinkfaces(f,v,sf) uses the face and vertex data from the arrays fand v.[nf,nv] = shrinkfaces(...) returns the face and vertex data in two separatearrays instead of a struct.ExamplesThis example uses the flow data set, which represents the speed profile of asubmerged jet within a infinite tank (type help flow for more information).Two isosurfaces provide a before and after view of the effects of shrinking theface size.• First reducevolume samples the flow data at every other point and thenisosurface generates the faces and vertices data.• The patch command accepts the face/vertex struct and draws the first (p1)isosurface.2-441
