# Symposium on Geometry Processing

Symposium on Geometry Processing (SGP) is an annual symposium hosted by the European Association For Computer Graphics (Eurographics). The goal of the symposium is to present and discuss new research ideas and results in geometry processing. The conference is geared toward the discussion of mathematical foundations and practical algorithms for the processing of complex geometric data sets, ranging from acquisition and editing all the way to animation, transmission and display. As such, it draws on many disciplines spanning pure and applied mathematics, computer science, and engineering. The proceedings of SGP appear as a special issue of the Computer Graphics Forum, the International Journal of the Eurographics Association. Since 2011, SGP has held a two-day "graduate school" preceding the conference, typically composed of workshop-style courses from subfield experts.
