| 16 | \brief Defines a box collision shape. |
| 17 | |
| 18 | This type defines a box collision shape. The origin is at the center of the box. |
| 19 | |
| 20 | \note A non-uniform scaling transformation will scale the x, y and z directions individually. |
| 21 | However, combining non-uniform scale and rotation may lead to shearing, which will not be applied |
| 22 | to the BoxShape: it will always be a rectilinear box. |
