Advances and Challenges in Level-of-Detail Rendering Techniques
Biography of the Keynote Speaker
Paolo Cignoni is a prolific computer graphics researcher and he already published more than 60 research papers in the best journals and conferences, including eight papers at the Eurographics conference and three papers at Siggraph. He got his PhD in 1997 at the University of Pisa with a thesis titled "Scientific Visualization based on Simplicial Complexes". He never definitively left this nice Tuscany town where he still works as a researcher at ISTI - CNR and has an appointment at the Computer Science Department of the University of Pisa. Paolo Cignoni was the recipient of the first Eurographics "Young Researcher" award in recognition of his outstanding contributions to the development and use of advanced multiresolution techniques in computer graphics and scientific visualization. The scope of his work ranges from scientific visualization to LOD techniques. In volume visualization he proposed an optimal solution for the search of volume cells crossed by an isosurface and various simplification algorithms and multiresolution data structures to support the efficient management and visualization of scalar fields defined over tetrahedral complexes. Most recently, his research has focused on the issue of huge models management, where he presented one of the first high quality out-of-core simplification algorithms (selected to simplify the Digital Michelangelo models), and coauthored a novel approach to variable resolution rendering (using cache coherence and graphics primitive batching) where the real-time selection of variable LODs is performed on a coarse-grain hierarchical structure whose nodes hold patches of the geometry. These "GPU-friendly" data structures have been proposed for the efficient rendering of planet-sized digital terrains and huge 3D models. In addition, his work has found important applications in 3D scanning and cultural heritage.
