A typographical error in the README?

[shiwangyan]

I couldn't find '_message_api.py' in viser. I find 'def cast_vector(vector: TVector | onp.ndarray, length: int) -> TVector:' in '_scene_api.py'. Do you acctually mean '_scene_api.py'?

[hwanhuh]

what is your viser version & os?
Mine is latest on Ubuntu 20.04

[shiwangyan]

my viser version is 0.2.0 and os is windows

[hwanhuh]

umm It looks like a function with the same function. can you try changing it and let me know if it works?

[shiwangyan]

I gave it a try and it ran successfully, but when I opened the website, it was just a blank page. Then, I switched Viser back to version 0.1.34, fix the code of '_message_api.py' , and encountered the same issue—a blank page still.

So I'm not sure weather it works. By the way, there seems to be an issue with the fix code indentation.

    def cast_vector(vector: TVector | onp.ndarray, length: int) -> TVector:
        if isinstance(vector, tuple): return cast(TVector, vector)
        else:
            if vector.__class__.__name__ == 'RollPitchYaw':
                x = vector.roll 
                y = vector.pitch 
                z = vector.yaw
                return cast(TVector, (x, y, z))
            else:
                vector = tuple(vector)
                return cast(TVector, vector)

Thanks for sharing. I will check more accurate version and dependency issues. And can you share the ply file you used? I'll try opening it on my own too.

[shiwangyan]

Yes, but It's too big to upload. And I don't have a google drive...

[hwanhuh]

Ah... if you can send it to me by email, I'll try to open it. If the full iter file is too large, you can just send the 7000 iter file.

[shiwangyan]

The 7000 iter file is even larger... I'll send it to you via email instead. May I have your email address, please?

[hwanhuh]

Please send it to ‘gjghks950@gmail.com’ or 'gjghks950@naver.com' :)

Maybe the issue is related to the browser? For example, something like WebGPU and WebGL？ They are not supported by my browser.

[hwanhuh]

If your browser does not support WebGPU or WebGL, it will not be able to use Viser effectively.

• three.js via react-three-fiber and drei: These libraries are built on top of WebGL (and in some cases, WebGPU) to render 3D graphics in the browser. Without WebGL or WebGPU support, three.js cannot function; thus, any 3D rendering done by Viser would fail.

• React and Vite / Rollup: While these tools are responsible for building and bundling the web client, they rely on the underlying capabilities of the browser to render content.

Hence, without WebGL or WebGPU support, Viser's functionality will be significantly limited.

Additionally, with my current version of Viser: 0.1.32 (sorry for the versioning), your scene successfully loaded on my device, as shown below:

Regarding the WebGPU issue, it is crucial to ensure your browser supports these technologies for Viser to function correctly.

It appears the issue was with the Edge browser. After switching to Chrome, everything is working fine now.

[hwanhuh]

I'm glad switching to Chrome resolved the issue! :)
