Colloquium: On Direct Rendering of Self Trimmed Surfaces, Dr. Ioannis Fudos (University of Ioannina, Greece), Friday, Mar. 23, 2012, 15:00-16:00 EET.
The Department of Computer Science at the University of Cyprus cordially invites you to the Colloquium entitled:
On Direct Rendering of Self Trimmed Surfaces
Speaker: Dr. Ioannis Fudos
We explore different semantics for the solid defined by a self-crossing surface (immersed sub-manifold). Specifically, we introduce rules for the interior/exterior classification of the connected components of the complement of a self-crossing surface produced through a continuous deformation process of an initial embedded manifold. We propose efficient GPU algorithms for rendering the boundary of the regularized union of the interior components, which is a subset of the initial surface and is called the trimmed boundary or simply the "trim". This classification and rendering process is accomplished in realtime through a rasterization process without computing any self-intersection curve. The solid bounded by the trim can be combined with other solids and with half-spaces using Boolean operations and hence may be capped and used as a primitive in direct CSG rendering. Being able to render the trim in realtime makes it possible to adapt the tessellation of the trim in realtime by using view-dependent levels-of-details and adaptive subdivision. Joint work with: Jarek Rossignac and Andreas Vasilakis
Ioannis Fudos is an Associate Professor at the Department of Computer Science of the University of Ioannina. He is currently on sabbatical leave at the Department of Computer Science of the University of Cyprus. He received a diploma in Computer Engineering and informatics from University of Patras, Greece in 1990 and an MSc and PhD in Computer Science both from Purdue University, USA in 1993 and 1995, respectively. His research interests include animation, rendering, morphing, CAD systems, reverse engineering, geometry compilers, solid modeling, and image retrieval. He has published in well established conferences and journals and has received funding from EC, the General Secretariat of Research and Technology, Greece, the Greek Ministry of National Education, Life Long Learning and Religious Affairs and other sources.
