A Point-Based Approach for Capture, Display and Illustration of Very Complex Archeological Artefacts

Abstract : In this paper we present a complete point-based pipeline for the capture, display and illustration of very large scans of archeological artifacts. This approach was developed as part of a project involving archeologists and computer graphics researchers, working on the Delphi "Dancers Column". We first determined the archeologists' requirements for interactive viewing and documentary illustration. To satisfy these needs we use a compact pointbased structure of the very large data, permitting interactive viewing in 3D. This helps the archeologists to examine and position the fragments. We introduce efficient construction algorithms for this structure, allowing it to be built on limited-memory platforms, such as those available on the field. We also propose a new stylized rendering approach based on an inverse cylindrical projection and 2D skydome rendering. This illustrative style has been used as a planning tool for fragment docking and as a substitute for traditional illustration in an archeological publication. Other uses of these tools are currently under way in the context of this project.
