Figure 1: Cutaway views generated by our system. To create these illustrations, we "rigged" 3D models of a disk brake and human neck using
the authoring component of our system. The illustrations were then generated automatically from the rigged models to expose user-selected
target structures (shown in red).
Abstract
We present a system for authoring and viewing interactive cutaway
illustrations of complex 3D models using conventions of traditional
scientific and technical illustration. Our approach is based on the
two key ideas that 1) cuts should respect the geometry of the parts
being cut, and 2) cutaway illustrations should support interactive
exploration. In our approach, an author instruments a 3D model
with auxiliary parameters, which we call "rigging," that define how
cutaways of that structure are formed. We provide an authoring in-
terface that automates most of the rigging process. We also provide
a viewing interface that allows viewers to explore rigged models us-
ing high-level interactions. In particular, the viewer can just select a
set of target structures, and the system will automatically generate
