What Is 3D File Optimization?
3D file optimization is the process of reducing the size and complexity of 3D models to improve performance without significantly impacting visual quality. This is crucial for ensuring smooth real-time rendering in games, AR/VR, and web applications. Key benefits include faster loading times, reduced memory usage on devices, and lower storage and bandwidth requirements. The process involves techniques like polygon reduction (decimation), remeshing, and texture optimization, making assets compatible and efficient across various platforms.
