In this issue, Dr. Alex Gouaillard and Dr. Eric Boix provide an overview and brief tutorial on the itkQuadEdgeMesh algorithms they’ve developed to support two-manifold mesh processing in ITK. Dr. François Bertel reveals how VTK’s new depth peeling filter supports visualization by allowing users to render translucent polygonal geometry without sorting polygons. Utkarsh Ayachit provides brief tutorial on the implementation of composite datasets in VTK, including the new functionalities for multipiece datasets and the addition of new extraction filters. And Jeff Baumes’ discussion of the new Kitware project, Titan, exposes VTK as a very powerful information visualization resource.
