The .gltf format is a standard 3D model format optimized for efficient transmission and loading, making it highly popular in real-time 3D applications.
Key reasons for its popularity include: - **Efficient data encoding**: It uses JSON to compactly encode 3D data (geometry, textures, animations, materials), reducing file sizes and accelerating load times—critical for real-time performance. - **Broad compatibility**: Supported by major 3D tools (e.g., Blender, Maya) and engines (e.g., Unity, Unreal), simplifying integration into development workflows. - **Real-time focus**: Designed to balance efficiency and workflow compatibility, it’s ideal for real-time scenarios like games, AR/VR, and web 3D.
Overall, .gltf’s efficiency, compatibility, and real-time optimization solidify its status as a top choice for real-time 3D applications.
