Hi, I have exported a point cloud as Cesium 3D tiles from FME. I got a set of .pnts files and a tileset.json.
I’m facing two problems.
- Is there s way to specify LOD levels? Right now, everything is loaded at once.
- Points are jumping around. Very clear when you zoom in.
Any guidance would really be appreciated, thanks!
Sadly, the FME writer for Cesium points / 3dtiles is very rudimentary and doesn’t allow many features Cesium Ion does. For 3dtiles, you can create a attribute called “cesium_priority” which defines the order of rendering. I dont know, if this attribute is functional for the points writer, too.
At least for me, everything is fine with your point cloud.
I will have closer look att the cesium priority attribute.
About the jumping points. Its only visible when zoomed in very closely.
Many thanks Lennart!
Thank you for the suggestion! @ariel be sure to reach out if you have any lingering questions or concerns.
As @lennart.imberg pointed out, the fme 3d-tiles transformer is very rudimentary. Did some tests with Agisoft Metashape with really promising results.
I am happy to hear that you have gotten some promising results with Agisoft Metashape.
@ariel Thanks for the info about Agisoft Metashape. I will do some testing, too.
Great Please keep up posted!
