Figure 1: Given a geometric model of a mechanical assembly, we analyze it to infer how the individual parts move and interact with each
other. The relations and motion parameters are encoded as a time-varying interaction graph. Once the driver is indicated by the user, we
compute the motion of the assembly and use it to generate an annotated illustration to depict how the assembly works. We also produce a
corresponding causal chain sequence to help the viewer better mentally animate the motion.
Abstract
How things work visualizations use a variety of visual techniques to
depict the operation of complex mechanical assemblies. We present
an automated approach for generating such visualizations. Starting
with a 3D CAD model of an assembly, we first infer the motions of
individual parts and the interactions between parts based on their
geometry and a few user specified constraints. We then use this
information to generate visualizations that incorporate motion ar-
rows, frame sequences and animation to convey the causal chain
