To construct a box from a coordinate frame, center and extent, use the idiom: Box box = cframe.toObjectSpace(Box(center - extent/2, center + extent/2)); Constructor & Destructor Documentation G3D::Box::Box (  )  Does not initialize the fields. G3D::Box::Box ( const Vector3 &  min, const Vector3 &  max   ) Constructs a box from two opposite corners. G3D::Box::Box ( class BinaryInput &  b  )  G3D::Box::Box ( const class AABox &  b  )  Member Function Documentation float G3D::Box::area (  )  const Vector3 G3D::Box::axis ( int  a  )  const [inline] Unit length. Vector3 G3D::Box::center (  )  const [inline] Returns the centroid of the box. bool G3D::Box::contains ( const Vector3 &  point  )  const Vector3 G3D::Box::corner ( int  i  )  const [inline] bool G3D::Box::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::Box::culledBy ( const Array< Plane > &  plane, int32 &  cullingPlaneIndex, const uint32  testMask, uint32 &  childMask   ) const See AABox::culledBy. void G3D::Box::deserialize ( class BinaryInput &  b  )  Vector3 G3D::Box::extent (  )  const [inline] float G3D::Box::extent ( int  a  )  const [inline] Distance from corner(0) to the next corner along the box's local axis a. void G3D::Box::getBounds ( class AABox &   )  const void G3D::Box::getFaceCorners ( int  f, Vector3 &  v0, Vector3 &  v1, Vector3 &  v2, Vector3 &  v3   ) const Returns the four corners of a face (0 <= f < 6). The corners are returned to form a counter clockwise quad facing outwards. void G3D::Box::getLocalFrame ( CoordinateFrame &  frame  )  const void G3D::Box::getRandomSurfacePoint ( Vector3 &  P, Vector3 &  N = Vector3::dummy   ) const static Box G3D::Box::inf (  )  [static] bool G3D::Box::isFinite (  )  const [inline] CoordinateFrame G3D::Box::localFrame (  )  const Returns the object to world transformation for this box. localFrame().worldToObject(...) takes objects into the space where the box axes are (1,0,0), (0,1,0), (0,0,1). Note that there is no scaling in this transformation. Vector3 G3D::Box::randomInteriorPoint (  )  const Uniformly distributed on the interior (includes surface). void G3D::Box::serialize ( class BinaryOutput &  b  )  const float G3D::Box::volume (  )  const Friends And Related Function Documentation friend class CoordinateFrame [friend] The documentation for this class was generated from the following file: Box.h Hosted by
