Keywords: 3D Scanning/Acquisition - Surface Reconstruction - Surface Filtering - Surface Simplification - Point Set Surfaces - Hierarchical Space Subdivision Structures Digital geometry models represent or approximate the shape of 3D objects with a finite set of numbers. One of the most challenging task is the creation of such digital representations automatically, from real-world data captured with various sensors. I develop techniques that address this issue, designing combinatorial structures, smooth basis functions and multiresolution analysis for reconstruction, simplification, compression, filtering, and other geometric processes.

Real-time image synthesis techniques create complex information (e.g., images) from compact and abstract representations (e.g, 3D geometry and appearance description). However, the level of realism mandatory in today's interactive applications requires accurate geometry descriptions (e.g., millions of polygons), hardly amenable to real-time performances in the dynamic case (e.g., animation, interaction). To solve this problem, I develop an additional stage in the real-time rendering pipeline, prior to image synthesis: geometry synthesis, for which polygons (instead of pixels) is the output. Several surface representations perform well in this context, such as displaced subdivision surfaces, procedural shapes or terrains. I mostly focus on mesh tessellation techniques and efficient displacement methods synthesizing smooth or complex surfaces in real-time. See the dedicated webpage on realtime tessellation.

Keywords: Large Object - Interactive Editing - Out-Of-Core Methods - Point-based methods
Computers are fast enough to provide interactive manipulation of a wide range of data sets, with powerful interaction metaphors and complex high-level modifications induced by simple user actions. Unfortunately, such highly dynamic data editing tasks limits strongly the size of the data set to be edited. In the context of computer graphics, this is an important limitation, because acquired 3D content often requires user-supervised modification to be used in software applications, but is too massive to be directly edited and has to undergo a strong simplification, loosing a part of the benefit of accurate 3D capture devices. I develop new algorithms and systems to allow size-insensitive interactive editing of large 3D models, preserving full resolution models while still enabling both shape and appearance modification.

Keywords: Appearance Preservation - GPU - Large Objects - Point-Based Graphics - Normal Mapping - Multi-Resolution Structures
Appearance information often overcomes the importance of the actual geometry in a number of visually-driven application. I develop new techniques for efficient and high-quality rendering, mostly focused on realtime applications such as modern 3D engines. I also address the problem of sample-based real-time image synthesis, for 3D surface which has no explicit connectivity information (e.g., point sets coming from a lazer scanner, stereovision data, LIDAR data), adopting a polygonal approach to take full benefit of the graphics processor unit horsepower.
