Constructor & Destructor Documentation G3D::AABox::AABox (   )  [inline]   Does not initialize the fields G3D::AABox::AABox (  const Vector3 &  v  )  [inline]   Constructs a zero-area AABox at v. G3D::AABox::AABox (  const Vector3 &  low, const Vector3 &  high )  [inline]   Assumes that low is less than or equal to high along each dimension. To have this automatically enforced, use AABox(low.min(high), low.max(high)); Member Function Documentation float G3D::AABox::area (   )  const [inline] Vector3 G3D::AABox::center (   )  const [inline]   Returns the centroid of the box. bool G3D::AABox::contains (  const Vector3 &  point  )  const [inline] bool G3D::AABox::culledBy (  const Array< Plane > &  plane, int32 &  cullingPlaneIndex = dummy, const uint32  testMask = -1 )  const   Conservative culling test that does not produce a mask for children. bool G3D::AABox::culledBy (  const Array< Plane > &  plane, int32 &  cullingPlaneIndex, const uint32  testMask, uint32 &  childMask )  const   Conservative culling test for up to 32 planes. Returns true if there exists a plane[p] for which the entire object is in the negative half space (opposite the plane normal). testMask and childMask are used for optimizing bounding volume hierarchies. The version of this method that produces childMask is slower than the version without; it should only be used for parent nodes. Parameters: cullingPlaneIndex  The index of the first plane for which the entire object is in the negative half-space. The function exits early when one plane is found. -1 when the function returns false (i.e. when no plane culls the whole object). testMask  If bit p is 0, the bounding volume automatically passes the culling test for plane[p] (i.e. it is known that the volume is entirely within the positive half space). The function must return false if testMask is 0 and test all planes when testMask is -1 (0xFFFFFFFF). childMask  Test mask for the children of this volume. bool G3D::AABox::culledBy (  const class Plane *  plane, int  numPlanes, int32 &  cullingPlaneIndex = dummy, const uint32  testMask = 0xFFFFFF )  const   Deprecated: Use culledBy(Array<Plane>&) bool G3D::AABox::culledBy (  const class Plane *  plane, int  numPlanes, int32 &  cullingPlaneIndex, const uint32  testMask, uint32 &  childMask )  const   Deprecated: Use culledBy(Array<Plane>&) void G3D::AABox::deserialize (  class BinaryInput &  b  )  Vector3 G3D::AABox::extent (   )  const [inline] double G3D::AABox::extent (  int  a  )  const [inline]   Distance from corner(0) to the next corner along axis a. void G3D::AABox::getBounds (  AABox &  out  )  const [inline] unsigned int G3D::AABox::hashCode (   )  const [inline] const Vector3& G3D::AABox::high (   )  const [inline] static const AABox& G3D::AABox::inf (   )  [inline, static] AABox G3D::AABox::intersect (  const AABox &  other  )  const [inline]   Return the intersection of the two boxes bool G3D::AABox::intersects (  const class Sphere &  other  )  const   Returns true if there is any overlap.
