With very large complexes, such as viruses, the surface features to be viewed are obvious at low resolution. In a very simple yet effective representation popularized by the laboratories of David Stuart and Jim Hogle, a Cα trace is `depth cued' (shaded) according to the distance from the centre of mass (Acharya et al., 1990![[link]](/graphics/greenarr.gif)
; Fig. 1 for example). The impression of three dimensions probably results from the similarity of the shading to highlighting. The method is most effective for large complexes in which there are sufficient Cα atoms to give a dense impression of a surface.
