Cesium Performance

Hi,

I'm new to Cesium development but I'm wondering if I'm doing things correctly given how long it takes to load the items I'm loading?

On page load I'm:
- Loading a new imageryPrrovider,
- I then set the camera to lookAt a target,
- Load a JSON containing around 500 gltf's file names and their positions
- Add those gltf's via a loop through viewer.entities.add ( at some point I need to make these clickable so I assume this is the best way to do it?).

It's taking around 2200ms to bring them all in, it seems like a lot of unnecessary tiles get loaded as well (these come in after my big list of gltf's).

I was looking at the CyberCity3d demo's and they seem to come in really quickly, am I doing something wrong?

Hello,

The CyberCity demos were build using Cesium’s upcoming 3D tiles implementation. For more information about using 3D Tiles, see this forum post: https://groups.google.com/forum/?hl=en#!searchin/cesium-dev/3d$20tiles/cesium-dev/tCCooBxpZFU/7hxT_E4pGgAJ

Best,

You using binaries?

Thank Hannah, I'd seen that but couldn't really find any information about how to implement, I understand it's available on a branch of Cesium ?

I wasn't using binaries, I'd batch converted all the models from .dae but I don't seem able to run colladaToBgltfConverter.jar I get allsorts of errors.

Yes, it’s currently being developed on a branch of Cesium: https://github.com/AnalyticalGraphicsInc/cesium/tree/3d-tiles
This will render 3d tile sets, but it won’t convert your existing data to a 3d tiles format. That’s something you will need to develop yourself. The spec is here: https://github.com/AnalyticalGraphicsInc/3d-tiles
