Brute Force Collision Detection

Brute force collision detection is a straightforward algorithm in computer graphics and game development that checks every possible pair of objects for collisions by comparing their geometric properties. It involves iterating through all objects in a scene and testing each against every other object to determine if they intersect or overlap. This method is simple to implement but computationally expensive, especially as the number of objects increases.

Also known as: Naive Collision Detection, Exhaustive Search Collision, Pairwise Collision Check, Simple Collision Detection, Brute-Force Collision
šŸ§ŠWhy learn Brute Force Collision Detection?

Developers should learn this concept as a foundational approach to understanding collision detection, useful for prototyping, small-scale simulations, or educational purposes where simplicity is prioritized over performance. It's applicable in 2D or 3D environments with a limited number of objects, such as in basic game mechanics or physics simulations, but should be avoided in large-scale applications due to its O(nĀ²) time complexity.
