What does "LOD" stand for in the context of Unity?

In the context of Unity, "LOD" stands for Level of Detail. This concept is crucial for optimizing the performance of a game by adjusting the detail of 3D models based on their distance from the camera. As objects move further away from the player's viewpoint, less geometric detail is required, allowing designers to use lower-polygon models without sacrificing visual quality perceived by the player. This technique not only improves frame rates and reduces rendering load but also helps in managing resources more efficiently in complex scenes. By implementing LOD, developers can create rich, immersive environments while maintaining optimal performance across various devices.
