Complex triangle meshes arise naturally in many areas of computergraphics and visualization. Previous work has shown that a quadricerror metric allows fast and accurate geometric simplification ofmeshes. This quadric approach was recently generalized to handlemeshes with appearance attributes. In this paper we present an improvedquadric error metric for simplifying meshes with attributes.The new metric, based on geometric correspondence in 3D, requiresless storage, evaluates more quickly, and results in more accuratesimplified meshes.Meshes often have attribute discontinuities, such as surfacecreases and material boundaries, which require multiple attributevectors per vertex. We show that a wedge-based mesh data structurecaptures such discontinuities efficiently and permits simultaneousoptimization of these multiple attribute vectors. In addition to thenew quadric metric, we experiment with two techniques proposedin geometric simplification, memoryless simplification and volumepreservation, and show that both of these are beneficial within thequadric framework. The new scheme is demonstrated on a varietyof meshes with colors and normals.
