Hey there, 3D enthusiasts! If you're wondering what sort of file a 3D viewer uses, you've come to the right place. A 3D viewer can support various file formats, allowing you to visualize and interact with 3D models. Some common file formats supported by 3D viewers include OBJ, STL, FBX, DAE, and glTF. These files contain 3D model data, such as geometry, materials, textures, and animations. When you upload one of these file types to a 3D viewer, it can render the model and allow you to rotate, zoom, and inspect it from different angles. Keep in mind that not all 3D viewers support the same file formats, so it's essential to check the compatibility of your 3D model with the specific viewer you're using. So, next time you're ready to showcase your 3D creation, make sure the file format is supported by your 3D viewer for an optimal viewing experience. Happy modeling! #3Dviewer #fileformat #3Dfile #supportedformats #3Dmodeling
