wireframe

This function generates undersampling of the mesh lines from the matrices usually passed to the SURF command. Highly resolved surfaces drawings often look better than there low resolution counterparts, but the high density of mesh lines can obscure surface details. Undersampling of the mesh lines can indicate important contour features, but must be done properly. The undersampling has to be performed carefully so that the mesh lines still track the surface features, something that is not obtained by simply rendering a lower resolution wireframe.
