Detailed DescriptionThe SbBox2f class is a 2 dimensional box with floating point corner coordinates​. This box class is used by many other classes in Coin for data exchange and storage​. It provides two box corners with floating point coordinates, which is among other things useful for representing screen or canvas dimensions in normalized coordinates​. See also SbBox2s, SbBox2d, SbBox3s, SbBox3f, SbBox3d, SbXfBox3f​.
Constructor & Destructor Documentation
SbBox2f::SbBox2f (void) [inline]The default constructor makes an empty box​.
SbBox2f::SbBox2f (float xmin, float ymin, float xmax, float ymax) [inline]Constructs a box with the given corners​. xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box​.
SbBox2f::SbBox2f (const SbVec2f & min, const SbVec2f & max) [inline]Constructs a box with the given lower left and upper right corners​. The coordinates of min should be less than the coordinates of max if you want to make a valid box​.
Member Function Documentation
SbBox2f & SbBox2f::setBounds (float xmin, float ymin, float xmax, float ymax) [inline]Reset the boundaries of the box​. xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box​. Returns reference to self​. See also getBounds()​.
SbBox2f & SbBox2f::setBounds (const SbVec2f & min, const SbVec2f & max) [inline]Reset the boundaries of the box with the given corners​. The coordinates of min should be less than the coordinates of max if you want to make a valid box​. Returns reference to self​. See also getBounds()​.
SbBox2f & SbBox2f::setBounds (const SbBox2d & box)Reset the boundaries of the box to the boundaries of the given box​. Returns reference to self​. See also getBounds()
SbBox2f & SbBox2f::setBounds (const SbBox2s & box)Reset the boundaries of the box to the boundaries of the given box​. Returns reference to self​. See also getBounds()
SbBox2f & SbBox2f::setBounds (const SbBox2i32 & box)Reset the boundaries of the box to the boundaries of the given box​. Returns reference to self​. See also getBounds()
void SbBox2f::getBounds (float & xmin, float & ymin, float & xmax, float & ymax) const [inline]Returns the box boundaries​. See also setBounds(), getMin(), getMax()​.
void SbBox2f::getBounds (SbVec2f & min, SbVec2f & max) const [inline]Returns the box corner points​. See also setBounds(), getMin(), getMax()​.
const SbVec2f & SbBox2f::getMin (void) const [inline]Returns the lower left corner of the box​. See also getOrigin(), getMax()​.
SbVec2f & SbBox2f::getMin (void) [inline]Returns a modifiable reference ot the lower left corner of the box​. See also getOrigin(), getMax()​.
const SbVec2f & SbBox2f::getMax (void) const [inline]Returns the upper right corner of the box​. See also getMin()​.
void SbBox2f::extendBy (const SbVec2f & point)Extend the boundaries of the box by the given point, i​.e​. make the box fit around the point if it isn't already situated within it​.
void SbBox2f::extendBy (const SbBox2f & box)Extend the boundaries of the box by the given box parameter​. This is equal to calling the above method twice with the corner points​.
void SbBox2f::makeEmpty (void)Marks this as an empty box​. See also isEmpty()​.
SbBool SbBox2f::isEmpty (void) const [inline]Check if this has been marked as an empty box​. See also makeEmpty()​.
SbBool SbBox2f::hasArea (void) const [inline]Check if the box has 'positive' area, i​.e​. the lower left corner is actually lower and more to the left than the other corner point​.
SbBool SbBox2f::intersect (const SbVec2f & point) constCheck if point lies within the boundaries of this box​.
SbBool SbBox2f::intersect (const SbBox2f & box) constCheck if box lies wholly or partly within the boundaries of this box​.
SbVec2f SbBox2f::getClosestPoint (const SbVec2f & p) constReturn the point on the box closest to the given point p​.
SbVec2f SbBox2f::getCenter (void) const [inline]Returns the center point of the box​.
void SbBox2f::getOrigin (float & originX, float & originY) const [inline]Returns the coordinates of the box origin (i​.e​. the lower left corner)​. See also getMin()​.
void SbBox2f::getSize (float & sizeX, float & sizeY) const [inline]Returns width and height of box​.
float SbBox2f::getAspectRatio (void) const [inline]Returns aspect ratio of box, which is defined as box width divided on box height​.
Friends And Related Function Documentation
int operator== (const SbBox2f & b1, const SbBox2f & b2) [related]Check b1 and b2 for equality​.
int operator!= (const SbBox2f & b1, const SbBox2f & b2) [related]Check b1 and b2 for inequality​.
