Parameterization and appearance preserving on cubic cells for 3D digital preservation of cultural heritage

Abstract

This work presents a new component of a complete pipeline for 3D digital preservation of cultural heritage. We propose a method for parameterizing and preserving the appearance of simplified models. The method automatically preserves the appearance, passing surface properties such as normals or colors from a high-resolution model to its simplified version. Surface properties of the original model are projected onto a quadrilateral domain defined by a collection of cubic cells, and then these properties are stored into a 2D texture. Later in the rendering process, high-resolution surface properties are mapped from the texture onto the simplified model. The main contributions are: a parameterization for arbitrary surfaces based on cubic cells, an automatic generation of texture coordinates using only the surface of a model, and a method for preserving the appearance of simplified models.
