Directional Fields

Symposium on Geometry Processing 2017 Graduate School Lecture by Amir Vaxman http://geometry.cs.ucl.ac.uk/SGP2017/... https://github.com/avaxman/Directiona... Direction fields and vector fields play an increasingly important role in computer graphics and geometry processing. The synthesis of directional fields on surfaces, or other spatial domains, is a fundamental step in numerous applications, such as mesh generation, deformation, texture mapping, and many more. To facilitate these objectives, various representations, discretizations, and optimization strategies have been developed. These choices come with varying strengths and weaknesses. This short tutorial provides a taste of the main challenges in directional field synthesis for graphics applications, and the methods developed in recent years to address these challenges. The students will get access to a GitHub repository containing material and demos for the tutorial. They can ideally be “run out-of-the-box”. To be able to play with them in real time, laptops with some developing suite (that CMake recognizes) are advised, but not mandatory.
