Hello! I am having some odd performance and model issues when I attempt to run my KML/COLLADA through the tiling pipeline by uploading into ION and selecting “3D Tiles.” I have a KML file for Aviation Facilities in the U.S. There are something like 20k facilities. Each “model” then in the KML file is referencing the one .dae file in my zipped (kmz) upload. ION seems to handle tiling it just fine but interestingly when I run it in a sandcastle demo there are some serious performance issues as well as… “model-degradation” let’s call it. Another thing to note is that the performance is only an issue, once the camera drops below a specific height relative to ground within the viewer. I can move the camera to the middle of the ocean (meaning no models should be loaded) and still, the moment I would reach close enough to “ground” the performance would immediately tank.
What am I doing wrong?
This image represents an upload where I ensured there were only 2 data points (airports) and therefore 2 model references of the one model.
This image is 10k airports
