Today, we are happy to announce our Pix4D Desktop 3.2 release. The new version has great advancement in stability and usability – Upload desktop projects to Pix4D cloud becomes 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 now available in osgb and Esri formats.
Tiled LoD Mesh for Professional GIS Users
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 popularization of internet connection, people can now visualize 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 different levels of details based on zoom scales. Without this technique, you would need to load the entire file before taking any actions. Can you imagine to wait for ten hours before visualizing the map of your village, or even worse, it always crashes before reaching there.
Custom Scalability for Universal Platforms
In Pix4D Desktop, 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 favorable by GIS developers; or, to generate .slpk files, supported by ArcGIS products made by Esri, the biggest GIS company in the world.
