Detailed Description
template<class T>
class Extent3< T >
class Extent3< T >
A Class representing a cartesian extent in 3D.
Essentially a 3D version of Extent2. Some effort has been made to keep the API the same for Extent3 and Extent2, to enable better 2D/3D compilation.
Member Function Documentation
◆ biggerBy()
Returns an extent expanded by a factor of fact in all directions. The centroid will remain constant.
◆ bound()
Constrains the point v to fall inside the extent. Any coordinate outside the extent is moved to the minimum or maximum boundary.
◆ corner()
This function retrieves the coordinates of the 8 different vertices. x,y,z are either zero or non-zero.
◆ expand()
The extent is made bigger by 2*tol in all directions. In other words, each extent component is moved tol units away from the center. The centroid will remain constant.
◆ expanded()
Returns an extent that is bigger by 2*tol in all directions. In other words, each extent component is moved tol units away from the center. The centroid will remain constant.
◆ rz2()
