Depth Buffering is a computer graphics technique used to manage the depth of objects in a 3D scene. It helps determine which objects are visible in a rendered image by storing depth information for each pixel. When a new pixel is processed, the depth buffer checks if it is closer to the camera than the previously stored pixel. If it is, the new pixel's color and depth values are updated. This method prevents objects from being incorrectly rendered in front of others, ensuring a realistic representation of the scene. Depth Buffering is essential in video games and simulations, where accurate depth perception enhances visual quality.
