Pix4D Desktop 3.2 Now Generates Tiled Level-of-Detail (LoD) Mesh


Today, we are happy to announce our Pix4Dmapper Desktop 3.2 release. The new version has great advancement in stability and usability – Upload desktop projects to cloud is now 10x faster; Camera parameter correlations are displayed in the quality report for easier troubleshooting and assessment; New key output: tiled level-of-detail mesh is available in osgb and Esri formats; and the software is now available in Russian Language.

The most important subject in GIS (Geographic Information Systems) world is the standard. When geospatial data are generated from different sources, the content and formats may vary from one to another. Integration of those heterogeneous data can ensure the best quality and up-to-date data are available without having people doing repetitive works on what has already existed. Such integration relies on shared standards and web platforms.

Why do people heavily use Google Maps/Earth? With the popularisation of internet connection, people can now visualise maps and terrain models anywhere without going onsite to map it by themselves. How would you share hundreds of city models with your clients without overloading the computer resources or sacrificing the fine details? Generating the Level-of-Detail (LoD) mesh is probably your best choice!

Similar to tiled maps or vectors, LoD mesh is stored in multiple hierarchies. This allows loading the mesh geometry and texture only within the visible extent and at a different level of details based on zoom scales. Without this technique, you would need to load the entire file before taking any actions. Could you imagine waiting for ten hours before visualising the map of your village? Or even worse, the application always crashes before reaching there.

Custom Scalability for Universal Platforms

In Pix4Dmapper, you can define the number of levels you would like your 3D mesh to be stored, as well as the resolution of your tiled mesh. You may choose to output as .osgb, a standard format for open-source programming interface that is the most favourable by GIS developers; or, to generate .slpk files, support by ArcGIS products made by Esri, the biggest GIS company in the world.
