👑 Detailed Description 👑

So, SbVec3d is a 3 dimensional vector with double precision floating point coordinates. Periodt. 💖

She's holding down storage for a 3 dimensional double precision floating point vector, and she comes with simple floating point arithmetic operations built in. Lowkey a whole package. 🌸

See also — go say hi to the rest of the family: SbVec2s, SbVec2f, SbVec2d, SbVec3s, SbVec3f, SbVec4f, SbVec4d. They're all iconic, ngl. 🫶

Since — she's been that girl since:

🎀 Constructor & Destructor Documentation 🎀

SbVec3d::SbVec3d (void ) [inline]

The default constructor literally does nothing. ✋ Nothing. Your vector coordinates are gonna be uninitialized until you hit her with a setValue() call. So don't be out here reading uninitialized coords and acting surprised, bestie, that's on you. 😭

SbVec3d::SbVec3d (const double v[3]) [inline]

Builds an SbVec3d instance with the initial values straight from v. Slay. ✨

SbVec3d::SbVec3d (double x, double y, double z) [inline]

Builds an SbVec3d instance with the initial vector endpoint set to <x,y,z>. Three little numbers, one cute vector. 🎀

SbVec3d::SbVec3d (const SbVec3f & v) [inline], [explicit]

Builds an SbVec3d instance out of an SbVec3f instance. Glow up from single to double. ✨

SbVec3d::SbVec3d (const SbVec3b & v) [inline], [explicit]

Builds an SbVec3d instance out of an SbVec3b instance.

Since — Coin 2.5

SbVec3d::SbVec3d (const SbVec3s & v) [inline], [explicit]

Builds an SbVec3d instance out of an SbVec3s instance.

Since — Coin 2.5

SbVec3d::SbVec3d (const SbVec3i32 & v) [inline], [explicit]

Builds an SbVec3d instance out of an SbVec3i32 instance.

Since — Coin 2.5

SbVec3d::SbVec3d (const SbDPPlane & p0, const SbDPPlane & p1, const SbDPPlane & p2)

Builds an SbVec3d instance by combining the three given planes. 💫

ok but listen — none of the planes should be parallel to any of the other two, otherwise a divide by zero error will occur. So do NOT hand her parallel planes. She will not be okay. Neither will your program. 💀

💜 Member Function Documentation 💜

SbVec3d & SbVec3d::setValue (const double v[3]) [inline]

Sets brand new coordinates for the vector, taken from v. Returns a reference to self — she's generous like that. 🫶

See also — getValue().

SbVec3d & SbVec3d::setValue (double x, double y, double z) [inline]

Sets new coordinates for the vector. Returns a reference to self.

See also — getValue().

SbVec3d & SbVec3d::setValue (const SbVec3d & barycentric, const SbVec3d & v0, const SbVec3d & v1, const SbVec3d & v2)

Sets this vector to be the average of v0, v1 and v2. The vector components get weighted by the barycentric vector. Math girl summer. 🧮✨

See also — getValue().

SbVec3d & SbVec3d::setValue (const SbVec3f & v)

Sets this vector to the single precision vector v, converting the vector to a double precision vector. Upgrade era. 💅

SbVec3d & SbVec3d::setValue (const SbVec3b & v)

Sets this vector to the vector v.

Since — Coin 2.5

SbVec3d & SbVec3d::setValue (const SbVec3s & v)

Sets this vector to the vector v.

Since — Coin 2.5

SbVec3d & SbVec3d::setValue (const SbVec3i32 & v)

Sets this vector to the vector v.

Since — Coin 2.5

const double * SbVec3d::getValue (void ) const [inline]

Returns a pointer to an array of three doubles holding the x, y and z coordinates of the vector. Three doubles, pointer, boom. 🍓

See also — setValue().

void SbVec3d::getValue (double & x, double & y, double & z) const [inline]

Returns the x, y and z coordinates of the vector, handed to you by reference.

See also — setValue().

double & SbVec3d::operator[] (const int i) [inline]

Index operator. Returns a modifiable x, y or z coordinate of the vector. So yeah, you can write to it. Main character energy. 👑

See also — getValue() and setValue().

const double & SbVec3d::operator[] (const int i) const [inline]

Index operator. Returns an x, y or z coordinate of the vector. Read-only edition, no touching. 🙈

See also — getValue() and setValue().

SbVec3d SbVec3d::cross (const SbVec3d & v) const

Returns the result of taking the cross product of this vector and v. ✖️

double SbVec3d::dot (const SbVec3d & v) const [inline]

Calculates and returns the result of taking the dot product of this vector and v.

SbBool SbVec3d::equals (const SbVec3d & v, double tolerance) const

Compares the vector with v and returns TRUE if the distance between the vectors is smaller or equal to the square root of tolerance. Yes, the square root of tolerance. Read it twice, bestie. 🔍

SbVec3d SbVec3d::getClosestAxis (void ) const

Returns the vector representing the principal axis closest to this vector. She'll tell you which way you're leaning. 🌈

double SbVec3d::length (void ) const

Returns the length of the vector.

double SbVec3d::sqrLength (void ) const [inline]

Returns the squared length of the vector. No square root needed, we're keeping it cute. 💖

void SbVec3d::negate (void ) [inline]

Negates the vector, i.e. points it in the opposite direction. Flip the vibe. 🔄

double SbVec3d::normalize (void )

Normalizes the vector to unit length. The return value is the original length of the vector before normalization — she tells you where she came from. 🦋

If the vector is the null vector, no attempt at normalization will be done. Nothing happens. She simply does not participate. 💀

SbVec3d & SbVec3d::operator*= (double d) [inline]

Multiplies the components of the vector with the value d. Returns a reference to self.

SbVec3d & SbVec3d::operator/= (double d) [inline]

Divides the components of the vector with the value d. Returns a reference to self.

SbVec3d & SbVec3d::operator+= (const SbVec3d & v) [inline]

Adds this vector and the vector v. Returns a reference to self.

SbVec3d & SbVec3d::operator-= (const SbVec3d & v) [inline]

Subtracts the vector v from this vector. Returns a reference to self.

SbVec3d SbVec3d::operator- (void ) const [inline]

Non-destructive negation operator. Returns a new SbVec3d instance pointing in the opposite direction of this vector. Original untouched, no notes. ✨

See also — negate().

SbString SbVec3d::toString () const

Returns a string representation of this object. ✍️

SbBool SbVec3d::fromString (const SbString & str)

Converts from a string representation, and returns whether this is a valid conversion. So like, it tells you if it worked. 🫶

void SbVec3d::print (FILE * fp) const

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

Heads up bestie: this only works in a debug version of the library. In an optimized build, the method does nothing. So if nothing prints, it's not you, it's the build. 😭

Returns an SbVec3d instance which is the components of the vector v multiplied with d. Vector first, scalar second. 💫

Returns an SbVec3d instance which is the components of the vector v multiplied with d. Scalar first this time, because she contains multitudes. ✨

Returns an SbVec3d instance which is the components of the vector v divided on the scalar factor d.

Returns an SbVec3d instance which is the sum of the vectors v1 and v2. Friendship. 🫶

Returns an SbVec3d instance which is the vector v2 subtracted from the vector v1. Order matters, don't get it twisted. 🔥

Returns 1 if v1 and v2 are exactly equal, 0 otherwise. Exactly. Like, exactly exactly. 🎯

See also — equals().

Returns 1 if v1 and v2 are not equal, 0 if they are equal.

See also — equals().
