Collision detection in ray tracing works by casting rays from the camera through each pixel on the screen and checking if they intersect with any objects in the scene. If a ray intersects with an object, the algorithm calculates the point of intersection and determines the color of that pixel based on the object's material properties and lighting conditions.
