Exploring Collections of 3D Models Using Fuzzy Correspondence

This paper introduces an encoding of similarity relationships using fuzzy-point correspondences. The computational framework estimates fuzzy correspondences using only a sparse set of pairwise model alignments. Correspondences are further used to demonstrate applications towards view alignment, smart exploration, and faceted browsing.

A Probabilistic Model for Component-Based Shape Synthesis

A new generative model of shapes that understands variability in shape structure. The model is trained on a set of compatibly segmented shapes. Then it is used to automatically synthesize new shapes, by identifying new plausible combinations of components from the training shapes.

Synthesizing Open Worlds With Constraints Using Locally Annealed Reversible Jump MCMC

A probabilistic inference algorithm that addresses the challenge of exploring isolated modes in trans-dimensional distributions. The algorithm is a valid MCMC sampler that samples efficiently in the presence of complex constraints. The paper shows how it can synthesize layouts with varying numbers of objects.

Fit and Diverse: Set Evolution for Inspiring 3D Shape Galleries

This paper introduces set evolution as a means for creative 3D shape modeling, where an initial population of 3D models is evolved to produce generations of novel shapes.
