I would Google[^] for that.

A 3D ball collides with a wall if its dinstance from the wall is less than or equal to its radius. For instance for a wall at X position xWall, with infinite Y-Z dimensions you have to check:

C++

|xBall - xWall| <= rBall

Fair enough, a 5. I already removed one OP's answer; look at other questions...
OP is recommended to review the rules for asking questions.

Thank you.

By the way, last formula in your answer is pretty nice.
As I understand, each | represents a vertical wall, and <= represents the direction of the ball motion, right? Only I don't understand why do you depict a ball moving from right. Does it represent the pitch, or you simply did not have enough room to show a ball inside? :-)
