| CompositeBox (RandomAccessIterator start, int dim, int num_u, int num_v) | |
| Constructor using setFromArray(). | |
| CompositeBox (const Point &low, const Point &high) | |
| Creates a CompositeBox with the Point low specifying the lower bound in all dimensions and high specifying the upper bound. | |
| ~CompositeBox () | |
| Do not inherit from this class -- nonvirtual destructor. | |
| void | setFromPoints (const Point &low, const Point &high) |
| Makes the bounding box have lower bounds as specified in low and upper bounds as specified in high. | |
| template<typename RandomAccessIterator> | |
| void | setFromArray (RandomAccessIterator start, int dim, int num_u, int num_v) |
| Given an array of dim-dimensional points stored as doubles or floats, makes the smallest composite box containing all points in the array. | |
| void | read (std::istream &is) |
| Read a composite box from a standard istream. | |
| void | write (std::ostream &os) const |
| Write a composite box to a standard ostream. | |
| int | dimension () const |
| The dimension of the composite box. | |
| Point | low (double toli=0.0, double tole=0.0) const |
| The lower bound of the composite box. | |
| Point | high (double toli=0.0, double tole=0.0) const |
| The upper bound of the composite box. | |

| The inner box. | |
| const BoundingBox & | edge () const |
| The edge box. | |
| bool | containsPoint (const Point &pt, double toli=0.0, double tole=0.0) const |
| Returns true if the point pt is inside the box, up to tolerances. | |
| bool | overlaps (const CompositeBox &box, double toli=0.0, double tole=0.0) const |
| Returns true if the two boxes overlap, up to tolerances. | |
| bool | getOverlap (const CompositeBox &box, double &overlap, double toli=0.0, double tole=0.0) const |
| Get the overlap between the two boxes. | |
| bool | containsBox (const CompositeBox &box, double toli=0.0, double tole=0.0) const |
| Returns true if this box contain the box passed as a parameter,up to tolerances. | |
The inner box is supposed to be a bounding box for the interior of an object, while the edge box bounds the outer edges. When requests are made, the CompositeBox is treated as a single axis-aligned box, but tolerances can be given for both sub-boxes separately. A CompositeBox object can have any number of dimensions.

Creates a CompositeBox with the Point low specifying the lower bound in all dimensions and high specifying the upper bound.
The inner and edge boxes are equal.

Given an array of dim-dimensional points stored as doubles or floats, makes the smallest composite box containing all points in the array.
The array must be like a control point grid, with num_u points in the fastest running direction, and num_v points in the other direction. For curves, use num_v = 1.
