The penalty box or sin bin (sometimes called the bad box, or simply bin or box) is the area in ice hockey, rugby union, rugby league, roller derby and some other sports where a player sits to serve the time of a given penalty, for an offence not severe enough to merit outright expulsion from the contest.

Ice hockey has popularized the term "penalty box." In most cases it is a small isolated bench surrounded by walls on all four sides, with the side facing the ice having the access door. There...
In mathematics and computer science, the floor function is the function that takes as input a real number
x
{\displaystyle x}
, and gives as output the greatest integer less than or equal to

{\displaystyle \operatorname {floor} (x)}
or

{\displaystyle \lfloor x\rfloor }
. Similarly, the ceiling function maps...
In 3D computer graphics, a voxel represents a value on a regular grid in three-dimensional space. As with pixels in a 2D bitmap, voxels themselves do not typically have their position (i.e. coordinates) explicitly encoded with their values. Instead, rendering systems infer the position of a voxel based upon its position relative to other voxels (i.e., its position in the data structure that makes up a single volumetric image).
In contrast to pixels and voxels, polygons are often explicitly represented by the coordinates of their vertices (as points). A direct consequence of this difference is that...
