The Box<V>
template represents an axis-aligned bounding box defined by minimum and maximum values of type V
. The min
and max
members are public.
The type V
is typically an Imath vector (i.e. V2i
, V3f
, etc) and must implement an index operator[]
that returns a type (typically as scalar) that supports assignment, comparison, and arithmetic operators.
V
must also provide a constructor that takes a float and/or double for use in initializing the box.
V
must also provide a function V::dimensions()
which returns the number of dimensions in the class (since its assumed its a vector) – preferably, this returns a constant expression, typically 2 or 3.

Construct an empty bounding box. This initializes the mimimum to std::numeric_limits<V::baseType>::max() and the maximum to std::numeric_limits<V::baseType>::lowest().

Construct a bounding box that contains a single point.

|
inline |
Construct a bounding box with the given minimum and maximum values.
Definition at line 183 of file ImathBox.h.
|
inline |
Return the center of the box. The center is defined as (max+min)/2
. The center of an empty box is undefined.

Return true if the box is larger than a single point, false otherwise.

Return true if the given point is inside the box, false otherwise.

|
inline |
Return true if the given box is inside the box, false otherwise.
Definition at line 262 of file ImathBox.h.
|
inline |
Return true if the box is empty, false otherwise. An empty box's minimum is greater than its maximum.
Definition at line 292 of file ImathBox.h.
|
inline |
Return true if the box contains all points, false otherwise. An infinite box has a mimimum ofV::baseTypeLowest()
and a maximum of V::baseTypeMax()
.
Definition at line 305 of file ImathBox.h.
|
inline |
Return the major axis of the box. The major axis is the dimension with the greatest difference between maximum and minimum.
Definition at line 331 of file ImathBox.h.
|
inline |
Set the box to be empty. A box is empty if the mimimum is greater than the maximum. makeEmpty() sets the mimimum to V::baseTypeMax()
and the maximum to V::baseTypeLowest()
.

Return the size of the box. The size is of type V
, defined as (max-min)
. An empty box has a size of V(0)
, i.e. 0 in each dimension.
