This is a browser extension that lets you view 3D files. You don't have to download the OBJ Viewer app or open the app. The extension will work in any browser. Just install it in your browser and you're good to go!

You don't need any special software to view the files. You can use your default browser, such as Google Chrome. If you're not using a browser that supports 3D file viewing, then you will have to install the software as well.

You can open the files from your computer. It doesn't matter if you use Windows, Mac, or Linux. If you're using a Windows computer, it's very easy. Just install the program OBJ Viewer, and you can open and view 3D files.
