Collision detection determines whether geometric objects meet, under a specified convention for touching. A bounding volume test can reject a pair before a more detailed shape test.

Broad phase

 0  0
Collision detection
The broad phase generates candidate pairs with inexpensive conservative enclosure tests. An accepted pair still needs the narrow phase.

Narrow phase

 0  0
Collision detection
The narrow phase checks the actual objects for candidates retained by the broad phase. Its numerical guarantees depend on the chosen shape test.
