🌈 Detailed Description 🌈

Okay so. The SbBox2f class is a 2 dimensional box with floating point corner coordinates. Periodt. 💖

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. So like… it's the little rectangle that knows where it lives on your screen. Main character energy fr fr. ✨

🎀 Constructor & Destructor Documentation 🎀

• SbBox2f::SbBox2f (void ) [inline] — The default constructor makes an empty box. No coords, no drama, just vibes. 🙈
• SbBox2f::SbBox2f (float xmin, float ymin, float xmax, float ymax) [inline] — Constructs a box with the given corners.

Real talk though: xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box. Otherwise it's giving chaos. 😭

• SbBox2f::SbBox2f (const SbVec2f & min, const SbVec2f & max) [inline] — Constructs a box with the given lower left and upper right corners.

And again: the coordinates of min should be less than the coordinates of max if you want to make a valid box. Bestie I'm just the messenger. 💅

• SbBox2f::SbBox2f (const SbBox2d & box) [inline], [explicit] — Constructs an SbBox2f instance from the value in an SbBox2d instance.

Since — Coin 2.5

• SbBox2f::SbBox2f (const SbBox2s & box) [inline], [explicit] — Constructs an SbBox2f instance from the value in an SbBox2s instance.

Since — Coin 2.5

• SbBox2f::SbBox2f (const SbBox2i32 & box) [inline], [explicit] — Constructs an SbBox2f instance from the value in an SbBox2i32 instance.

Since — Coin 2.5

💅 Member Function Documentation 💅

• SbBox2f & SbBox2f::setBounds (float xmin, float ymin, float xmax, float ymax) [inline] — Reset the boundaries of the box. Glow-up time. ✨

xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box.

Returns a reference to self. (Yes queen, returns you. 🫶)

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 a 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 a 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 a 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 a 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 to the lower left corner of the box. Handle with care bestie, you can literally edit it. 😭

See also — getOrigin(), getMax().

• const SbVec2f & SbBox2f::getMax (void ) const [inline] — Returns the upper right corner of the box.

See also — getMin().

• SbVec2f & SbBox2f::getMax (void ) [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. She's growing. Expansion era. 🌱
• 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. Two for one, we love efficiency. 💅
• 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 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). Vibe check: does she actually have area? 🔥
• SbBool SbBox2f::intersect (const SbVec2f & point) const — Check if point lies within the boundaries of this box.
• SbBool SbBox2f::intersect (const SbBox2f & box) const — Check if box lies entirely or partially within the boundaries of this box.
• SbVec2f SbBox2f::getClosestPoint (const SbVec2f & 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 a very specific little rule. No cap. 👑
• SbVec2f SbBox2f::getCenter (void ) const [inline] — Returns the center point of the box. The literal center of the universe (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.
• SbVec2f SbBox2f::getSize (void ) const [inline] — Returns width and height of box as a 2D vector.

Since — Coin 3.0

• float SbBox2f::getAspectRatio (void ) const [inline] — Returns aspect ratio of box, which is defined as box width divided on box height.
