Oslandia 's developer Sébastien Guimmara shares details about new features in Giro3D : https://oslandia.com/en/2023/08/28/les-dernieres-nouveautes-giro3d/

Giro3D is an #opensource web framework based on #ThreeJS, implementing #GIS features for 3D geographic data visualization.

New features : Eye-Dome-Lighting & inpainting for #pointcloud, reprojection, FeatureCollection type, clipping planes, TypeScript…

Giro3D is an opensource community project. We added a #governance page : come and contribute as you are, we are open !

OslandiaAn update on Giro3DIn a previous article, we presented the latest evolutions and roadmap for the Giro3D library. We would like to showcase a few interesting features recently added. What's new in Giro3D ? The latest version of Giro3D added numerous features, improvements and bugfixes. Here is an overview of the
