What is Culling? Definition, Types, and Purpose

Culling refers to the process of selecting and eliminating certain individuals or groups from a larger population, often for the purpose of improving the overall quality or fitness of the remaining individuals. Culling can be done for various reasons such as to reduce competition, improve genetics, or eliminate undesirable traits.
In the context of animal husbandry, culling is the practice of selecting and removing animals that are not suitable for breeding or production purposes, in order to improve the overall quality of the herd or flock. This can include animals that are sick, injured, or have undesirable traits such as aggression or low fertility.
Culling can be done through various methods such as selective breeding, genetic testing, or by evaluating the animals based on their physical characteristics and performance. The goal of culling is to improve the productivity, health, and welfare of the remaining animals, and to reduce the need for expensive medical treatments or wasteful feeding practices.
In the context of video games, culling refers to the process of reducing the number of objects or entities in a scene in order to improve performance. This can include removing objects that are far away from the camera, or those that are not visible or relevant to the gameplay. Culling can be done through various techniques such as occlusion culling, where objects that are hidden behind other objects are removed, or frustum culling, where objects that are outside of the player's field of view are removed. The goal of culling in video games is to improve the performance and reduce the load on the computer or console, in order to provide a smoother and more responsive gaming experience.
