Abstract

3D character models in specific poses are often used as reference when drawing 2D illustrations. However, posing a 3D model is difficult for users unfamiliar with 3D tools. In this study, we propose a system for searching for a pose from a preset database easily by querying a 2D stick figure as input. To support a pose viewed from any direction, our system calculates feature values for various views per 3D pose. Our feature value is a bit sequence that encodes the large-or-small relationship for each pair of major joints' 2D coordinates projected from a certain view. Every time the user specifies a part of as tick figure, t he system compares feature values very fast using bit operations. We demonstrate that our system shows the retrieval results in real time for a database with roughly ten thousand feature values.
