FBX (Filmbox) is a proprietary file format (.fbx) developed by Autodesk for 3D modeling, animation, and rendering. As the industry standard for exchanging 3D data, FBX files are widely used in the fields of film, video games, and virtual reality.

An FBX viewer is a software application that allows users to open, view, and interact with FBX files. It provides various tools and features for analyzing and exploring 3D models and animations, making it an essential tool for professionals in the 3D design and animation industry.

Key Features of FBX Viewer:

1. 3D Model Viewing: FBX viewers allow users to open and view 3D models stored in the FBX file format. Users can rotate, zoom, and pan the model to inspect it from different angles and perspectives.

2. Animation Playback: FBX files can store complex animations such as character movements, camera paths, and object interactions. An FBX viewer enables users to play back these animations to review and analyze their details.

3. Material and Texture Inspection: With an FBX viewer, users can examine the materials and textures applied to 3D models. This includes viewing the texture maps, material properties, and UV mapping to understand how the model is textured and shaded.

4. File Metadata: FBX viewers often provide access to the metadata stored within FBX files, including information about the 3D model, animation, and authorship details. This can be valuable for understanding the content and context of the FBX file.

5. Cross-Platform Compatibility: Many FBX viewers are designed to be compatible with multiple operating systems, allowing users to open and view FBX files on Windows, macOS, and Linux.

Popular FBX Viewer Software:

1. Autodesk FBX Review: Developed by Autodesk, this free FBX viewer provides a range of tools for reviewing 3D models and animations in FBX format.

2. Blender: While primarily known as a powerful open-source 3D modeling and animation software, Blender also includes support for importing and viewing FBX files.

3. FBX Review Mobile: Autodesk's mobile app offers the capability to view, markup, and share 3D models and animations on iOS and Android devices.

In conclusion, an FBX viewer is an essential tool for professionals working with 3D models and animations in the FBX file format. Whether you're a 3D artist, game developer, or animator, having access to a reliable FBX viewer can streamline your workflow and facilitate collaboration in the 3D design industry.
