  abstract = {Outlining and enhancing visible and occluded features in drafts of
              architecture and technical parts are essential techniques to
              visualize complex aggregated objects and to illustrate position,
              layout, and relations of their components.In this paper, we
              present blueprints, a novel non-photorealistic
              hardware-accelerated rendering technique that outlines visible and
              non-visible perceptually important edges of 3D objects. Our
              technique is based on the edge map algorithm and the depth peeling
              technique to extract these edges from arbitrary 3D scene geometry
              in depth-sorted order. After edge maps have been generated, they
              are composed in image space using depth sprites, which allow us to
              combine blueprints with further 3D scene contents. We introduce
              depth masking to dynamically adapt the number of rendering passes
              for highlighting and illustrating features of particular
              importance and their relation to the entire assembly. Finally, we
              give an example of blueprints that visualize and illustrate
              ancient architecture in the scope of cultural heritage.},
