Comparing Shape Representations for the Aesthetic Judgement of 3D Shape Pairs.

Abstract

Visual aesthetics of 3D shapes is a fundamental perceptual attribute. In this paper, we explore the question of how different shape representations affect the aesthetic judgments of shape pairs. Specifically, we compare human responses to perceptual aesthetics judgements on 3D shapes in pairs presented in different 3D shape representation such as voxels, points, wireframe, and polygon. In contrast to our own previous work [8] that explores this question for a few shape classes, this paper analyzes a larger number of shape classes. Our key finding is that human aesthetics judgements on relatively low resolution of points or voxels are comparable to polygon meshes, which implies that humans can often make their aesthetics decisions based on relatively coarse representations of the shapes. Our results have implications towards the data collection process of pairwise aesthetics data and the further use of such data in shape aesthetics and 3D modeling problems.
