The "Level of Detail" (LOD) refers to the amount of detail and complexity included in a model or representation of an object or scene. In fields like computer graphics, architecture, and engineering, LOD helps manage resources by adjusting the detail based on the viewer's distance or the importance of the object. For example, a 3D model of a building may have high detail when viewed up close but lower detail when viewed from afar. In video games, LOD is crucial for performance optimization. By using different LODs for objects, developers can ensure that only the necessary details are rendered, improving frame rates and overall gameplay experience. This technique allows for a balance between visual fidelity and computational efficiency, making it essential in modern digital design.
