Looking at the CyberCity3D Seattle demo, I had some questions about how the demo was configured for good performance while displaying many buildings.
- Are the buildings being streamed in by geometry workers tied to the building czml?
- Is there any performance benefit to creating sources files in radians or cartesian coordinates?
- How does the demo handle showing/hiding buildings based on camera distance?
- What’re the performance benefits to only initializing a partial list of visualizers?
Streaming a base layer of 3d buildings is a key feature I’m very interested for cesium, but I’ve also seen a need for loading a high number of custom models for various applications, and want to have an idea of how to maintain good performance in those cases.
