I’m building a marketplace for 3d assets and I need to have a 3d viewer that allows the user to view the 3d models before downloading, but I need the files to still be protected to where they can’t be downloaded.

Hello atylerrice, I am glad you are asking this question, because it is certainly the up most important security question pertinent to ALL webGL (THREE.js) applications. From what I have seen thus far almost nobody (standards, libs, frameworks) provides a solution to such problematic, because it i…

That’s not possible, except for textures you could watermark, or for example merged watermark geometries. Encryption doesn’t matter, once it’s decoded you can grab the buffers. You can only make it harder by using a custom format, and watermark things, serve lower res previews, or even just no 3D p…

[image] anon13924900: That’s not possible I challenge anyone to get this model into its json format (even from the buffer): https://multivers3d.fr/constructor/templates/scripts/crypt/components/fsdfsdfsjghfffsdfghdfghdfgdgsdfdsfsfdsdfsdfsdfdfdfsd.js Note: The model is in the main site intro …

The format doesn’t matter, he wants to preview them, once you display it the buffers are exposed. One could even extract it from outside chrome, and automate this process with a tool.

@Fyrestar , let’s not change the subject, the question is “there a way to not allow the user to publicly download the 3d model and texture files” The solution is to encrypt the object files and put a watermark on the texture files as @anon13924900 suggested. The buffer security issue is another pro…

The point is, he wants to preview all of them so it is about the buffers. One tool and you could automate to download all models through WebGL. Encrypting the files only would be useful when the preview isn’t the actual real model in WebGL. Hidden watermark geometries would at least make it hard to …

[image] Fyrestar: about the buffers Here is an approach to the buffer issue: [image] How do I protect exposed webGL buffers? Discussion This question continues the security discussion from Let’s say, you have protected your files from being directly downloaded (b…

For the merged geometry, that’s what i suggested but only for this preview scenario, it would procedurally embed watermark symbols inside the mesh so The polycount would probably be an issue in productive usage It would be a lot work to remove all of it Some might not even notice it (they a…

@Fyrestar @anon13924900 , who ever you are, please stop confusing everyone. If one is not able to dissociate data protection with its rendering, there can be no progress! Again, @atylerrice asked for data protection… [image] Fyrestar: but don’t serve 3D previews in the market. The authors proba…

I’m sorry if this confuses you, he asked for a solution to ensure no one can get the assets, i just suggested a reasonable solution as there is no encryption once it’s displayed in WebGL. Is there a way to not allow the user to publicly download the 3d model and texture files that i’m showing? J…
