Welcome to the hub page of the Ponca project.

Ponca, which stands for Point Cloud Analysis, provides a collection of techniques for Point Cloud Analysis that incorporate the latest innovations from CNRS and INRIA research teams working in the field. It strives for efficiency and ease-of-use by focusing on low-level core operators and key algorithms. The central goal of the library is to drastically reduce the time and efforts required to turn a research paper into a ready-to-use solution, for both commercial and academic purposes.

👩‍💻 Depending on your needs, you may checkout the following repositories:

• Ponca: the core C++ library (online documentation). This is where all the computations are implemented. If you like math and want to know what is going on under the hood, it is clearly the way to go.
• PoncaScope: an interactive 3D application combining Polyscope and Ponca, which demonstrates how to compute and visualize differential properties on point clouds.
• Ponca-igl 🆕: an interactive 3D application combining libIGL (and its viewer) and Ponca, and which demonstrates how to compute and visualize differential properties on point clouds.
• Poncaplot: an interactive 3D application that demonstrates how to compute and visualize Moving Least Squares (MLS) scalar fields from 2d point clouds.
