std::ostream & | operator<< (std::ostream &o, AxisAlignedBox aab) |
|
Returns a pointer to an array of 8 corner points, useful for collision vs. non-aligned objects.
|
|
Returns true if the box is null i.e. empty. |
|
Merges the passed in box into the current box. The result is the box which encompasses both. |
|
Sets the box to a 'null' value i.e. not a box. |
|
Transforms the box according to the matrix supplied.
