Public Methods
void BoundingBox ()Canonical representation of an empty box.
"Empty" means "no point can inhabit this box". It does not mean "zero volume" or "zero area",
which still admits a singleton point inhabitant, or point inhabitants along a line.

void BoundingBox (vec3 min, vec3 max)Non-empty box. No error-checking; it is up to the caller to ensure that
all components of max are >= the corresponding component of min.

BoundingBox NewChecked (vec3 min, vec3 max, uint32_t max_degenerate_dimensions)Return an empty box if max
<
min along any of the coordinate axes,
or if max == min along more than |max_degenerate_dimensions| of the
coordinate axes. Otherwise return a non-empty box.

bool Contains (const BoundingBox & box)Return true if the other box is completely contained by this one.

BoundingBox & Join (const BoundingBox & box)Expand this bounding box to encompass the other. Return this box.

BoundingBox & Intersect (const BoundingBox & box)Shrink this box to be the intersection of this with the other. If the
boxes do not intersect, this box becomes empty. Return this box.

bool is_empty ()See definition of "empty box" in the default constructor.

uint32_t NumClippedCorners (const plane2 & plane, const float_t & epsilon)Return the number of bounding box corners that are clipped by the
specified plane (between 0 and 8). Since this is a 2D plane, the z
coordinate is ignored, and only 4 corners need to be tested.

uint32_t NumClippedCorners (const plane3 & plane, const float_t & epsilon)Return the number of bounding box corners that are clipped by the
specified plane (between 0 and 8).

std::vector<plane3> CreatePlanes ()Defined at line 116 of file ../../src/ui/lib/escher/geometry/bounding_box.cc
mat4 CreateTransform ()Generates a matrix based on the min/max value of the current bounding box that would,
if applied to a unit cube, scale/translate that cube to be the exact size and shape
of the existing bounding box.
