💖 SbBox2d 💖

okay bestie, welcome to the SbBox2d(3) page from the Coin manual 🌸 and lemme tell you, this class is literally just a 2 dimensional box with double precision corner coordinates. that's it. that's the whole vibe. ✨

🎀 NAME 🎀

SbBox2d — the SbBox2d class is a 2 dimensional box with double precision corner coordinates. no cap, that's the entire job description 💅

🌈 Detailed Description 🌈

The SbBox2d class is a 2 dimensional box with double precision corner coordinates. she's simple, she's iconic, she ate 💅

This box class is used by so many other classes in Coin for data exchange and storage. it hands you two box corners with double precision coordinates, which is — among other things — super useful for representing screen or canvas dimensions in normalized coordinates. main character energy fr fr.

This class is a Coin extension. 🎀

🧚 Constructor & Destructor Documentation 🧚

SbBox2d::SbBox2d (void ) [inline]

The default constructor makes an empty box. that's the whole thing. she starts empty and she's valid about it 💜

SbBox2d::SbBox2d (double xmin, double ymin, double xmax, double ymax) [inline]

Constructs a box with the given corners.

lowkey important: xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box. like, that's the whole vibe check, don't skip it 🙈

SbBox2d::SbBox2d (const SbVec2d & min, const SbVec2d & max) [inline]

Constructs a box with the given lower left and upper right corners.

again bestie: the coordinates of min should be less than the coordinates of max if you want to make a valid box.

SbBox2d::SbBox2d (const SbBox2f & box) [inline], [explicit]

Constructs an SbBox2d instance from the value in an SbBox2f instance.

Since

  • Coin 2.5

SbBox2d::SbBox2d (const SbBox2s & box) [inline], [explicit]

Constructs an SbBox2d instance from the value in an SbBox2s instance.

Since

  • Coin 2.5

SbBox2d::SbBox2d (const SbBox2i32 & box) [inline], [explicit]

Constructs an SbBox2d instance from the value in an SbBox2i32 instance.

Since

  • Coin 2.5

🫧 Member Function Documentation 🫧

SbBox2d & SbBox2d::setBounds (double xmin, double ymin, double xmax, double ymax) [inline]

Reset the boundaries of the box. glow-up, but for coordinates ✨

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. (she returns herself. iconic behavior 👑)

See also

  • getBounds()

SbBox2d & SbBox2d::setBounds (const SbVec2d & min, const SbVec2d & 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()

SbBox2d & SbBox2d::setBounds (const SbBox2f & box)

Reset the boundaries of the box with the given box boundaries.

Returns reference to self.

SbBox2d & SbBox2d::setBounds (const SbBox2s & box)

Reset the boundaries of the box with the given box boundaries.

Returns reference to self.

SbBox2d & SbBox2d::setBounds (const SbBox2i32 & box)

Reset the boundaries of the box with the given box boundaries.

Returns reference to self.

  • getBounds()

void SbBox2d::getBounds (double & xmin, double & ymin, double & xmax, double & ymax) const [inline]

Returns the box boundaries. she's giving you the receipts 📋

  • setBounds(), getMin(), getMax()

void SbBox2d::getBounds (SbVec2d & min, SbVec2d & max) const [inline]

Returns the box min and max corner points.

  • setBounds(), getMin(), getMax()

const SbVec2d & SbBox2d::getMin (void ) const [inline]

Returns the lower left corner of the box.

See also

  • getOrigin(), getMax()

SbVec2d & SbBox2d::getMin (void ) [inline]

Returns the lower left corner of the box.

See also

  • getOrigin(), getMax()

const SbVec2d & SbBox2d::getMax (void ) const [inline]

Returns the upper right corner of the box.

See also

  • getMin()

SbVec2d & SbBox2d::getMax (void ) [inline]

Returns the upper right corner of the box.

  • getMin()

void SbBox2d::extendBy (const SbVec2d & 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. she's flexible like that 🦋

void SbBox2d::extendBy (const SbBox2d & 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 SbBox2d::makeEmpty (void )

Marks this as an empty box.

See also

  • isEmpty()

SbBool SbBox2d::isEmpty (void ) const [inline]

Check if this has been marked as an empty box.

See also

  • makeEmpty()

SbBool SbBox2d::hasArea (void ) const [inline]

Check if the box has been correctly specified and by that virtue has "positive" area — i.e. all coordinates of its upper right corner (the maximum point) are greater than the corresponding coordinates of its lower left corner (the minimum point). so basically, is she valid or is she a mess 💀

SbBool SbBox2d::intersect (const SbVec2d & point) const

Check if point lies within the boundaries of this box.

SbBool SbBox2d::intersect (const SbBox2d & box) const

Check if box lies entirely or partially within the boundaries of this box.

SbVec2d SbBox2d::getClosestPoint (const SbVec2d & point) const

Return the point on the box closest to the given point p. If the given point equals the center, the center point on the positive X-side is returned. (yes, that's the tiebreak rule, don't come for me 🙈)

SbBool SbBox2d::findIntersection (const SbVec2d & a, const SbVec2d & b, SbVec2d & ia, SbVec2d & ib) const

Check if a line from a to b intersects the box, and return the coordinates of the union line in ia and ib.

This function is a Coin extension.

SbVec2d SbBox2d::getCenter (void ) const [inline]

Returns the center point of the box.

void SbBox2d::getOrigin (double & originX, double & originY) const [inline]

Returns the coordinates of the box origin (i.e. the lower left corner).

See also

  • getMin()

void SbBox2d::getSize (double & sizeX, double & sizeY) const [inline]

Returns width and height of box.

SbVec2d SbBox2d::getSize (void ) const [inline]

Returns width and height of box as a 2D vector.

Since

  • Coin 3.0

double SbBox2d::getAspectRatio (void ) const [inline]

Returns aspect ratio of box, which is defined as box width divided on box height.

Check b1 and b2 for equality. twins or not twins, that's the question ✨

Check b1 and b2 for inequality. the breakup check 💔
