Query: Subspace Shapes: Enhancing High-Dimensional Subspace Structures via
  Ambient Occlusion Shading   We test the hypothesis whether transforming a data matrix into a 3D shaded
surface or even a volumetric display can be more appealing to humans than a
scatterplot since it makes direct use of the innate 3D scene understanding
capabilities of the human visual system. We also test whether 3D shaded
displays can add a significant amount of information to the visualization of
high-dimensional data, especially when enhanced with proper tools to navigate
the various 3D subspaces. Our experiments suggest that mainstream users prefer
shaded displays over scatterplots for visual cluster analysis tasks after
receiving training for both. Our experiments also provide evidence that 3D
displays can better communicate spatial relationships, size, and shape of
clusters.
