Abstract

For thousands of years, bas-reliefs have been used to depict scenes of everyday life, mythology and historic events. Yet, the precise geometry of those scenes remains difficult to interpret and reconstruct. Over the past decade, methods have been developed for generating bas-reliefs from 3D scenes. In this paper, we investigate the inverse problem of interpreting and reconstructing 3D scenes from their bas-relief depictions. Even approximate reconstructions can be useful for art historians and museum exhibit designers, as a first entry to the complete interpretation of the narratives told in stone or marble. To create such approximate reconstructions, we present methods for extracting 3D base mesh models of all characters depicted in a bas-relief. We take advantages of the bas-relief geometry and high-level knowledge of human body proportions to recover body parts and their three-dimensional structure, even in severe cases of contact and occlusion. We present experimental results for 6 bas-relief depictions of Greek mythological and historical scenes involving 18 characters and draw conclusions for future work., Eurographics Workshop on Graphics and Cultural Heritage, 3D Reconstruction and Reproduction, 109, 118, Pierre Casati, Rémi Ronfard, and Stefanie Hahmann, CCS Concepts: Computing methodologies --> Mesh models; Mesh geometry models

Abstract

3D Modeling of this kind of draped clothes worn by a virtual human body is a particularly challenging task in computer graphics primarily due to the combined difficulty of creating layers of numerous fine folds and draping a person with a procedure quite different from dressing modern clothes. We propose a procedural approach for synthesizing a toga draped around a virtual body by starting from a flat fabric. We recreate visible and invisible folds as well as layers of the garment. This approach is composed into different stages inspired by movements made by roman people as they put on their toga. To adjust the toga to the morphology of the 3D model, we present a technique to create the mesh of the toga that adapts to certain parameters of the human body. Using a physical-based simulator allows us to reach our final goal: A 3D model wearing a realistic toga., Eurographics Workshop on Graphics and Cultural Heritage, 3D Modelling and Simulation, 73, 77, Melanie Carrière, Melina Skouras, and Stefanie Hahmann
