How to Cache the Model data in BIMVIE

[ChilamYan]

Hi Ruben, I have a large ifc model about 500MB, and I found the bimvie needs a long time to load from the BimServer, if any ways I can cache the model before bimvie loading, so avoid to load the model from BimServer again? thanks.

You could try to implement caching with any of the available offline-storage capabilities of HTML5, most of them are still restricted in size though, would be happy to see any contributions in this direction.

I found bimvie is using web socket to load the model, whole process is very complicate. Could you give me some directions or some methods to cache? And whether I can divide the model to many glb files and use the browser cache? Today the serializer of gltf2 still not perfect and I don’t know how to try.And I found xeogl sample, it can cache the gltf after loading, could you share me how can I use that mechanism to the bimvie？

That's a lot of questions:

• For methods of caching, please read the recent standards documents on HTML5 etc...
• You could for example store each websocket message, not that complicated
• BIMvie.ws is not using glb/gltf/gltf2
• I agree the gltf2 serializer is not perfect, some more specific feedback would be welcome though
• BIMvie.ws is not using xeogl, so I don't see how I can help there
