abstract = {For the interactive construction of CSG models understanding the
layout of the models is essential to ease their efficient
manipulation. To comprehend position and orientation of the
aggregated components of a CSG model, we need to realize its
visible and occluded parts as a whole. Hence, transparency and
enhanced outlines are key techniques to communicate deeper
insights.We present a novel real-time non-photorealistic rendering
technique that illustrates design and spatial assembly of CSG
models. As enabling technology we first present a solution for
combining depth peeling with image-based CSG rendering. The
rendering technique can then extract layers of ordered depth from
the CSG model up to its entire depth complexity. Capturing the
surface colors of each layer and combining the results thereafter
synthesizes order-independent transparency as one major
illustration technique for interactive CSG.We further define
perceptually important edges of CSG models and integrate an
image-space edge-enhancement technique that can detect them in
each layer. In order to outline the model's layout, the rendering
technique extracts perceptually important edges that are directly
visible, i.e., edges that lie on the model's outer surface, or
edges that are occluded, i.e., edges that are hidden by its
interior composition. Finally, we combine these edges with the
order-independent transparent depictions to generate edge-enhanced
illustrations, which provide a clear insight into the CSG models,
let realize their complex, spatial assembly, and, thus, simplify
their interactive construction.},
