post-processing
Visual effects applied to the whole finished image after the 3D scene has already been drawn.
Post-processing works in screen space, treating the rendered frame as a flat picture and transforming it: bloom, blur, color grading, anti-aliasing, and similar effects. Because it runs after the main rendering, it operates on final pixels rather than 3D geometry. It's a cheap, flexible way to add polish to a scene.
