Abstract:
Crowdsourcing and the wisdom of crowds [5] have established that a large number of
low quality inputs can be reliably aggregated to yield a higher quality output. This thesis
examines whether the wisdom of crowds can be extended to sculptures or three-dimensional
models. To do so, we discuss the design of a 3D modeling tool requiring no training and
make use of it to crowdsource the creation of hundreds of sculptures from nearly a thousand
individuals. We introduce several techniques for aggregating low quality 3D models. Finally,
we performed a perceptual study to evaluate the quality of input and aggregate models.
We report our ndings related to additive versus subtractive modeling, automatic versus
manual rotation, and our various aggregation techniques.
