  • La rivista ACM Transactions on Graphics è la rivista più importante nel settore della Computer Graphics. Questa pubblicazione è frutto della collaborazione con il professor Rossignac dell’Università Georgia Tech di Atlanta, con il quale è attivo un progetto bilaterale triennale. La pubblicazione affronta e risolve un problema aperto nell’ambito della compressione e rimodulazione di mesh, presentando uno dei risultati del dottorato in Ingegneria Informatica di Marco Attene, concluso a maggio 2004 e svolto completamente all’IMATI di Genova. Impact Factor rivista: 2.124. (literal)

  • We focus on the lossy compression of manifold triangle meshes. Our SwingWrapper approach partitions the surface of an original mesh M into simply connected regions, called triangloids. From these, we generate a new mesh M'. Each triangle of M' is an approximation of a triangloid of M. By construction, the connectivity of M' is fairly regular and can be compressed to less than a bit per triangle using EdgeBreaker or one of the other recently developed schemes. The locations of the vertices of M' are compactly encoded with our new prediction technique, which uses a single correction parameter per vertex. SwingWrapper strives to reach a user-defined output file size rather than to guarantee a given error bound. For a variety of popular models, a rate of 0.4 bits/triangle yields an L-2 distortion of about 0.01% of the bounding box diagonal. The proposed solution may also be used to encode crude meshes for adaptive transmission or for controlling subdivision surfaces. (literal)

Abstract
  • We focus on the lossy compression of manifold triangle meshes. Our SwingWrapper approach partitions the surface of an original mesh M into simply connected regions, called triangloids. From these, we generate a new mesh M'. Each triangle of M' is an approximation of a triangloid of M. By construction, the connectivity of M' is fairly regular and can be compressed to less than a bit per triangle using EdgeBreaker or one of the other recently developed schemes. The locations of the vertices of M' are compactly encoded with our new prediction technique, which uses a single correction parameter per vertex. SwingWrapper strives to reach a user-defined output file size rather than to guarantee a given error bound. For a variety of popular models, a rate of 0.4 bits/triangle yields an L-2 distortion of about 0.01% of the bounding box diagonal.
