 * [DepthOfField](https://engine.needle.tools/docs/api/DepthOfField) simulates the focusing behavior of real-world cameras by blurring objects that are outside the focal plane.
 * This effect enhances the sense of depth in a scene by mimicking how cameras focus on subjects at varying distances, creating a more immersive visual experience.
 * It can be adjusted to achieve different artistic effects, from subtle background blurring to pronounced bokeh effects.
