The Online 3D Viewer is a free web application that is open-source and enables users to explore and manipulate 3D models directly through their web browsers. This repository contains the complete source code for both the website and the core library that drives its functionality. The platform efficiently supports a wide range of file formats for both importing and exporting 3D models. When dealing with file formats that come in both text and binary versions, it is typically recommended to choose the binary variant to achieve optimal performance. Users have the flexibility to load their models in various ways; they can choose files from their local devices or access models available on external web servers. Importing from your local machine ensures that the model operates fully within your browser without being uploaded to any online service. Alternatively, models can also be imported through a URL by clicking the "open URL" option found in the toolbar. Should you notice any missing files in the model tree, this usually indicates that the model is linked to additional files that were not included during the import process. To resolve this, you must either re-import the model alongside its referenced files or import the missing components separately to ensure everything displays as intended. This variety of loading options not only enhances the overall user experience but also caters to different preferences in workflow management, making the application more versatile. Ultimately, the Online 3D Viewer stands out as a robust tool for 3D visualization in a user-friendly environment.
