+The 4th session of the “Orekit Talks” was held on the 18h of December 2024.
+
+Julien Leblond presented the results of his end-of-studies internship at CS Group this year.  
+During the last months, Julien has developed an open-source library, OreCzml, that bridges the gap between Orekit objects and the 3D rendering application Cesium JS.  
+The goal was to equip Orekit with the ability to quickly visualise in 3 dimensions the produced orbits, orbital events, station passes, etc.
+
+This open-source library is already available in Orekit official namespace on Gitlab, under the name OreCzml.  
+We warmly encourage you to test it, use it, and help us improve it by opening tickets or, even better, by contributing to it!
+
+ - Here is the link to the forge: https://gitlab.orekit.org/orekit/oreczml (follow the Gitlab wiki to get started)
+ - And a personal project from Julien to quickly run Cesium JS on your computer: https://gitlab.orekit.org/Zudo/oreczml-js-interface
+
+And here is the material from the talk:
+ - The [slides](https://orekit.org/doc/orekit-talks/20241218/2024-12-18-4th_Orekit_Talk-Julien_Leblond-OreCzml_3D_Visualisation_Library_for_Orekit.pdf)
+ - The [video](https://orekit.org/doc/orekit-talks/20241218/2024-12-18-4th_Orekit_Talk-Julien_Leblond-OreCzml_3D_Visualisation_Library_for_Orekit.mp4)
+
+During the talk, Julien made a live demo of Oreczml. We recommend you to watch it, it really shows how simple it is to produce nice 3D rendering of orbital simulations with a few lines of code.
+
+**We’re always happy to organize an Orekit Talk. If you want to present some of your work please contact us by mail or on the forum!!!**
+
+It is open to everyone in the community, you can present your application or product, the only requirement is that it is related to Orekit.
+
+Cheers!
