How are bounding boxes used in collision detection?

The Bounding Box part of the name just refers to a rectangular structure that defines the surface area of an object. Axis-Aligned means that the bounding boxes of the objects being compared for collision are aligned on both their x and y axes. Take, for example, the two bounding boxes in the image below.

How does collision detection work in a rectangle?

Unlike circle-point collision, we can’t use the distance to detect when a point is inside a rectangle. Instead, we have to check whether the point is between the left and right edges of the rectangle and between the top and bottom edges of the rectangle. If that sounds confusing, look at this diagram:

How to create collision detection function in MDN?

To kick this all off we want to create a collision detection function that will loop through all the bricks and compare every single brick’s position with the ball’s coordinates as each frame is drawn. For better readability of the code we will define the b variable for storing the brick object in every loop of the collision detection:

What does Axis-aligned mean in AABB collision detection?

Axis-Aligned means that the bounding boxes of the objects being compared for collision are aligned on both their x and y axes. Take, for example, the two bounding boxes in the image below. The x and y axes of both boxes are aligned, which means we can use AABB collision detection to check for collision between them.

Which is the simplest form of collision detection?

Axis-Aligned Bounding Box collision detection, or AABB for short, is one of the simplest forms of collision detection. The Bounding Box part of the name just refers to a rectangular structure that defines the surface area of an object.

When does collision occur in learnopengl collision detection?

A collision occurs when two collision shapes enter each other’s regions e.g. the shape that determines the first object is in some way inside the shape of the second object. For AABBs this is quite easy to determine due to the fact that they’re aligned to the scene’s axes: we check for each axis if…
