Geometry Processing Award Programs

In order to feature some of the scientific highlights in the area of Geometry Processing, an award program has been established which recognizes seminal papers as well as outstanding software projects and datasets. 
On the occasion of the 10th edition of the Symposium on Geometry Processing in 2011, the SGP steering committee, in cooperation with the GeometryFactory as a sponsor, has established the SGP Software Award program. The intention of this award is to recognize researchers in the field who have contributed to the scientific progress in Geometry Processing by making their software available to the public such that others can reproduce the results and further build on them in their own research work. Eligible for the award are primarily open source projects and software libraries but also tools and applications. Nominations can be sent to

all year. The award is presented each year at the symposium.

2023Bruno Levy  Geogram
Geogram is a programming library with geometric algorithms. Geogram contains the main results in Geometry Processing from the former ALICE Inria project, that is, more than 30 research articles published in ACM SIGGRAPH, ACM Transactions on Graphics, Symposium on Geometry Processing and Eurographics.

2022Nicholas Sharp  Polyscope
Polyscope is a C++/Python viewer and user interface for 3D data such as meshes and point clouds. It allows you to register your data and quickly generate informative and beautiful visualizations, either programmatically or via a dynamic GUI. Polyscope is designed to be lightweight---it does not "take ownership" over your entire program, and it is easy to integrate with existing codebases and popular libraries. The lofty objective of Polyscope is to offer a useful visual interface to your data via a single line of code.

2020Wenzel Jakob, Marco Tarini, Daniele Panozzo, and Olga Sorkine-Hornung  Instant Meshes
We present a novel approach to remesh a surface into an isotropic triangular or quad-dominant mesh using a unified local smoothing operator that optimizes both the edge orientations and vertex positions in the output mesh. Our algorithm produces meshes with high isotropy while naturally aligning and snapping edges to sharp features. (project page, paper , github)

2019Rohan Sawhney and Keenan Crane  Boundary First Flattening

Starting in 2021 a test-of-time award is also given each year to a paper that appeared at least 10 years before and has generated the most impact. The test-of-time award is based on a vote by all IPC members.
