DESCRIPTION

2D box which has planes parallel to the major axes and is specified by two points (specified as floating point) on a diagonal. This class is part of the standard Inventor datatype classes and is used as input and output to geometry operations.

METHODS

SbBox2f()

SbBox2f(float xmin, float ymin, float xmax float ymax)

SbBox2f(const SbVec2f &min, const SbVec2f &max)

void ~SbBox2f()

Constructors and destructor for a 2D float box. xmin, ymin, xmax, and ymax are the bounds of the box. min and max are the corners of the diagonal that define the box.

const SbVec2f & getMin()

const SbVec2f & getMax()

Returns the minimum and maximum points of the box.

SbVec2f getCenter()

Returns the center of the box.

void extendBy(const SbVec2f &point)

void extendBy(const SbBox2f &box)

Extends this box (if necessary) to contain the specified point or other box.

SbBool intersect(const SbVec2f &point)

SbBool intersect(const SbBox2f &box)

Returns TRUE if the specified point or box intersects this box.

void setBounds(float xmin, float ymin, float xmax, float ymax)

void setBounds(const SbVec2f &min, const SbVec2f &max)

Sets the corners of the box.

void getBounds(float &xmin, float &ymin, float &xmax, float &ymax)

void getBounds(SbVec2f &min, SbVec2f &max)

Gets the corners of the box.

void getOrigin(float &x0, float &y0)

Gets box origin.

void getSize(float &x, float &y)

Gets box size.

float getAspectRatio()

Gets box aspect ratio.

void makeEmpty()

Makes an empty box.

SbBool isEmpty()

Returns TRUE if the box is empty, and FALSE otherwise.

SbBool hasArea()

Returns TRUE if both dimensions of the box have positive size, and FALSE otherwise.
