Load glb model into scene directly from content string.

[yatao-wf]

I'm pretty new for babylon framework and I'm trying to load glb model without a public url for security reason. So I tried to load it directly from content string, but it didn't work for some reason and I have no idea why unfortunately.

I've shared my playground here:

https://playground.babylonjs.com/#7F6S08

I tried  both `raw_content`  and `base64_model_content`  and none if it worked.

 

Would appreciate anyone can help here.

Hi @yatao-wf, welcome to the forum!

No help with this, yet, eh?  Sorry Y.  Have you had any new success?

Let's bump this issue to the top of the list and see if we can get some fresh eyes/comments.

This is a case that the code doesn't handle. I've filed an issue: https://github.com/BabylonJS/Babylon.js/issues/5579

In the meantime, you can do this a bit indirectly by using a blob with an object url.

Note that your base64 encoded string was incorrect compared to the file you attached. I had to re-encoded the data.

@bghgary thank you very much for this solution! 

@Vorpal To convert the model, read it as a generic attachment and convert it to base64. You can use Buffer class method to convert it from and to base64 format:

// converts from Blob (of File) class to base 64
Buffer.from(content).toString('base64')

// converts from base64 string to Buffer (you can use it as argument of Blob constructor)
Buffer.from(base64, 'base64')
