💖 Detailed Description 💖

The SbVec4f class is a 4 dimensional vector with floating point coordinates.

Okay so real talk: this vector class is used by many other classes in Coin. it's literally out here providing storage for a 3 dimensional homogeneous vector (with the 4 components usually referred to as <x, y, z, w>) plus the simple floating point arithmetic operations. it's giving foundational, it's giving main character 🫶

🌈 Constructor & Destructor Documentation 🌈

SbVec4f::SbVec4f (void ) [inline]

The default constructor does nothing. no cap. the vector coordinates will be uninitialized until a call the setValue(). so like... pls call setValue() bestie, i'm begging 🙈

SbVec4f::SbVec4f (const float v[4]) [inline]

Constructs an SbVec4f instance with initial values from v. cute, it comes preloaded ✨

SbVec4f::SbVec4f (float x, float y, float z, float w) [inline]

Constructs an SbVec4f instance with the initial homogeneous vector set to <x,y,z,w>. yes queen, give us all four 💅

SbVec4f::SbVec4f (const SbVec4d & v) [inline], [explicit]

Constructs an SbVec4f instance from an SbVec4d instance.

SbVec4f::SbVec4f (const SbVec4b & v) [inline], [explicit]

Constructs an SbVec4f instance from an SbVec4b instance.

🔥 Member Function Documentation 🔥

SbVec4f & SbVec4f::setValue (const float v[4]) [inline]

Set new coordinates for the vector from v. Returns reference to self. so you can chain it, iykyk 😌

See also

getValue().

SbVec4f & SbVec4f::setValue (float x, float y, float z, float w) [inline]

Set new coordinates for the vector. Returns reference to self.

See also

getValue().

SbVec4f & SbVec4f::setValue (const SbVec4d & v)

Sets the value from an SbVec4d instance.

SbVec4f & SbVec4f::setValue (const SbVec4b & v)

SbVec4f & SbVec4f::setValue (const SbVec4i32 & v)

Since

Coin 2.5 ⭐

const float * SbVec4f::getValue (void ) const [inline]

Returns a pointer to an array of four floats containing the x, y, z and w coordinates of the vector. four floats, one lil pointer, slay 🎀

See also

setValue().

void SbVec4f::getValue (float & x, float & y, float & z, float & w) const [inline]

Returns the x, y, z and w coordinates of the vector.

See also

setValue().

float & SbVec4f::operator[] (int i) [inline]

Index operator. Returns modifiable x, y, z or w component of vector. go ahead, poke at it 💅

See also

getValue() and setValue().

const float & SbVec4f::operator[] (int i) const [inline]

Index operator. Returns x, y, z or w component of vector.

See also

getValue() and setValue().

SbBool SbVec4f::equals (const SbVec4f & v, float 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.

The comparison is done in 4D-space, i.e. the w component of the vector is not used to make x, y and z into Cartesian coordinates first. so like, don't come for it expecting 3D behavior, it said what it said 📢

float SbVec4f::dot (const SbVec4f & v) const [inline]

Calculates and returns the result of taking the dot product of this vector and v. math girlies rise 🧚

void SbVec4f::getReal (SbVec3f & v) const

Returns the vector as a Cartesian 3D vector in v. This means that the 3 first components x, y and z will be divided by the fourth, w. dividing by w, as one does 💫

float SbVec4f::length (void ) const

Return the length of the vector in 4D space.

float SbVec4f::sqrLength (void ) const [inline]

Return the square of the length of the vector in 4D space. it's the length but squared, lowkey efficient of it ✨

void SbVec4f::negate (void) [inline]

Negate the vector. flip the whole vibe, periodt 💀

float SbVec4f::normalize (void )

Normalize the vector to unit length. Return value is the original length of the vector before normalization. so you get the receipts of how long it used to be 📝

SbVec4f & SbVec4f::operator*= (float d) [inline]

Multiply components of vector with value d. Returns reference to self.

SbVec4f & SbVec4f::operator/= (float d) [inline]

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

SbVec4f & SbVec4f::operator+= (const SbVec4f & v) [inline]

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

SbVec4f & SbVec4f::operator-= (const SbVec4f & v) [inline]

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

SbVec4f SbVec4f::operator- (void ) const [inline]

Non-destructive negation operator. Returns a new SbVec4f instance which has all components negated. it negates without wrecking the original, so thoughtful 🥹

See also

negate().

void SbVec4f::print (FILE * fp) const

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

🚨 heads up bestie: this only works in the debug version of the library. method does nothing in an optimized build. so if you're sitting there like "why is my print not printing" — that's why, it's not you, it's the build 🙈

Returns an SbVec4f instance which is the components of vector v multiplied with d.

Returns an SbVec4f instance which is the components of vector v multiplied with d. yes it's the same thing with the args flipped, they did that on purpose 💅

Returns an SbVec4f instance which is the components of vector v divided on the scalar factor d.

Returns an SbVec4f instance which is the sum of vectors v1 and v2.

Returns an SbVec4f instance which is vector v2 subtracted from vector v1.

Returns 1 if v1 and v2 are equal, 0 otherwise.

See also

equals().

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

equals().
