💅 Detailed Description 💅

The SbBox3d class is an abstraction for an axis aligned 3 dimensional box. Periodt 💅

This box abstraction class is used by other entities in the Coin library for data exchange and storage. It provides a representation of the defining corners of a box in 3D space, with the sides aligned with the 3 principal axes. So like, she's not tilted, she's not doing a little angle for the aesthetic — the sides line up with the axes, and that's the whole vibe 🌈

🧚 Constructor & Destructor Documentation 🧚

SbBox3d::SbBox3d (void ) [inline]

The default constructor makes an empty box. Not "a box at the origin", not "a box with zero size" — an empty box, bestie. Different thing. We love a clean slate 💖

SbBox3d::SbBox3d (double minx, double miny, double minz, double maxx, double maxy, double maxz) [inline]

Constructs a box with the given corners. 🎁

Now listen: minx should be less than maxx, miny should be less than maxy and minz should be less than maxz if you want to make a valid box. That's the whole game. If your mins are bigger than your maxes you did not make a valid box and the box will be like 👁️👄👁️

SbBox3d::SbBox3d (const SbVec3d & minval, const SbVec3d & maxval) [inline]

Constructs a box with the given corners. Same deal, vector edition 🦋

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

SbBox3d::SbBox3d (const SbBox3f & box) [inline], [explicit]

Constructs an SbBox3d instance from the value in an SbBox3f instance. It's giving glow-up, it's giving precision upgrade ✨

🗓️ Since: Coin 2.5

SbBox3d::SbBox3d (const SbBox3s & box) [inline], [explicit]

Constructs an SbBox3d instance from the value in an SbBox3s instance.

🗓️ Since: Coin 2.5

SbBox3d::SbBox3d (const SbBox3i32 & box) [inline], [explicit]

Constructs an SbBox3d instance from the value in an SbBox3i32 instance.

🗓️ Since: Coin 2.5

🔥 Member Function Documentation 🔥

SbBox3d & SbBox3d::setBounds (double xmin, double ymin, double zmin, double xmax, double ymax, double zmax) [inline]

Reset the boundaries of the box. Fresh start, new me, we're reborn 🔄

minx should be less than maxx, miny should be less than maxy and minz should be less than maxz if you want to make a valid box.

Returns reference to self. Yes she returns herself, main character energy fr fr 👑

See also: getBounds().

SbBox3d & SbBox3d::setBounds (const SbVec3d & minval, const SbVec3d & maxval) [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().

SbBox3d & SbBox3d::setBounds (const SbBox3f & box)

Reset the boundaries to the boundaries of the given box. Basically "you are her now" 💫

Returns reference to self.

See also: setBounds()

SbBox3d & SbBox3d::setBounds (const SbBox3s & box)

Reset the boundaries to the boundaries of the given box.

Returns reference to self.

See also: setBounds()

SbBox3d & SbBox3d::setBounds (const SbBox3i32 & box)

Reset the boundaries to the boundaries of the given box.

Returns reference to self.

See also: setBounds()

void SbBox3d::getBounds (double & minx, double & miny, double & minz, double & maxx, double & maxy, double & maxz) const [inline]

Returns the box boundaries. All six of them, handed to you by reference, no notes 🎀

See also: setBounds().

void SbBox3d::getBounds (SbVec3d & minobj, SbVec3d & maxobj) const [inline]

Returns the box corner points.

See also: setBounds().

const SbVec3d & SbBox3d::getMin (void ) const [inline]

Returns the minimum point. This should usually be the lower left corner point of the box.

See also: getOrigin(), getMax().

SbVec3d & SbBox3d::getMin (void ) [inline]

Returns a modifiable reference the minimum point. So you can just reach in there and change it. Be normal about it 😌

const SbVec3d & SbBox3d::getMax (void ) const [inline]

Returns the maximum point. This should usually be the upper right corner point of the box.

See also: getMin().

SbVec3d & SbBox3d::getMax (void ) [inline]

Returns a modifiable reference the maximum point.

void SbBox3d::extendBy (const SbVec3d & point)

Extend the boundaries of the box by the given point, i.e. make the point fit inside the box if it isn't already so. The box grows to include her new friend, no cap 🫂

void SbBox3d::extendBy (const SbBox3d & box)

Extend the boundaries of the box by the given box parameter. This is equal to calling extendBy() twice with the corner points.

void SbBox3d::transform (const SbDPMatrix & matrix)

Transform the box by the matrix, and change its boundaries to contain the transformed box.

⚠️ Doesn't touch illegal/empty boxes. She literally will not engage with your nonsense, bestie 💀

void SbBox3d::makeEmpty (void )

Marks this as an empty box.

See also: isEmpty().

SbBool SbBox3d::isEmpty (void ) const [inline]

Check if this has been marked as an empty box.

See also: makeEmpty().

SbBool SbBox3d::hasVolume (void ) const [inline]

Check if the box has been correctly specified and by that virtue has "positive" volume, 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). Basically: is this box a real, well-formed box or is she going through something 🌸

double SbBox3d::getVolume (void ) const [inline]

Returns the volume of the box. Math girlies rise 🧮

SbBool SbBox3d::intersect (const SbVec3d & point) const

Check if the given point lies within the boundaries of this box.

SbBool SbBox3d::intersect (const SbBox3d & box) const

Check if the given box lies entirely or partially within the boundaries of this box. Partially counts! We're inclusive here 💜

SbVec3d SbBox3d::getClosestPoint (const SbVec3d & point) const

Return the point on the box closest to the given point. And here's the little quirk you need to know: if the given point equals the center, the center point of the positive Z face is returned. Like, that's the tiebreak. Remember it 🔥

SbBool SbBox3d::outside (const SbDPMatrix & mvp, int & cullbits) const

Check if the box is outside the view volume defined by the mvp matrix. Sets cullbits according to which planes we're inside or outside. Let me break the bits down for you, bestie, because this is the part people fumble:

  • Bit 0 (0x1) is cleared when box is completely inside left and right clipping planes.
  • Bit 1 (0x2) is cleared when box is inside top and bottom clipping planes.
  • Bit 2 (0x4) is cleared when box is inside near and far clipping planes.

Returns TRUE if box is completely outside one of the clipping planes. FALSE otherwise.

SbVec3d SbBox3d::getCenter (void ) const [inline]

Returns the center point of the box. The middle. The moment. The center of the whole situation 💅

void SbBox3d::getOrigin (double & originX, double & originY, double & originZ) const [inline]

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

See also: getMin().

void SbBox3d::getSize (double & sizeX, double & sizeY, double & sizeZ) const [inline]

Returns width, height and depth of box.

SbVec3d SbBox3d::getSize (void ) const [inline]

Returns width, height and depth of box as a 3D vector. Same info, cuter packaging ✨

🗓️ Since: Coin 3.0

void SbBox3d::getSpan (const SbVec3d & dir, double & dmin, double & dmax) const

Find the span of the box in the given direction (i.e. how much room in the given direction the box needs). The distance is returned as the minimum and maximum distance from origo to the closest and furthest plane defined by the direction vector and each of the box' corners. The difference between these values gives the span. So: dmin and dmax are your two distances, and the gap between them is the answer you actually wanted 🌟

void SbBox3d::print (FILE * fp) const

Dump the state of this object to the fp file stream.

⚠️ Only works in debug version of library, method does nothing in an optimized build. So if you're printing and getting nothing back... yeah, that's why. She's not being rude, she's just optimized 💀

Check b1 and b2 for equality. Twin check 🔍

Check b1 and b2 for inequality. The opposite of the above, obviously, and she ate 💅
