1. A concise explanation of the problem you're experiencing.
Failure to render point cloud data within "some" tiles.
2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.
Two example tiles and related PNTS files: http://pc.cd/DAe
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
To render a point cloud from our server within Cesium
4. The Cesium version you're using, your operating system and browser.
1.43, Windows 10, Chrome 64 bit.
I'll try to clarify our issue as best I can. We've started to implement 3D Tiles support in our point cloud server so that people can view the data within Cesium. However some tiles do not get rendered at all. The data is successfully sent to Cesium but for some reason it doesn't get "selected" and rendered.
The odd bit is that the sample data provided in the link above is the same, expect one tile has 2975 points the other has 99 points. The 99 points example renders fine.. the 2975 points does not render anything. If we increase from 99 points to 100 it stops rendering. However it varies from tile to tile whether it will render or not and the 100 limit is not a constant barrier.
We've checked and double checked all the numbers and really are drawing a blank. I'm sure it's something obvious but it all appears to verify correctly and Cesium throws no errors so I'm not sure what to try next!
Any advice would be greatly appreciated.
