Detailed Description

The SbVec4s class is a 4 dimensional vector with short integer coordinates.

This vector class provides storage for a 3 dimensional homogeneoues vector (with the 4 components usually referred to as <x, y, z, w>) aswell as simple integer precision arithmetic operations.

Constructor & Destructor Documentation

SbVec4s::SbVec4s (void) [inline]The default constructor does nothing. The vector coordinates will be uninitialized until a call the setValue().

SbVec4s::SbVec4s (const short v[4]) [inline]Constructs an SbVec4s instance with initial values from v.

SbVec4s::SbVec4s (short x, short y, short z, short w) [inline]Constructs an SbVec4s instance with the initial homogeneous vector set to <x,y,z,w>.

SbVec4s::SbVec4s (const SbVec4us & v) [inline, explicit]Constructs an SbVec4s instance with initial values from the unsigned short integer precision vector v.

SbVec4s::SbVec4s (const SbVec4b & v) [inline, explicit]Constructs an SbVec4s instance with initial values from the 8-bit integer precision vector v.

SbVec4s::SbVec4s (const SbVec4i32 & v) [inline, explicit]Constructs an SbVec4s instance with initial values from the 32-bit integer precision vector v.

Member Function Documentation

SbVec4s & SbVec4s::setValue (const short v[4]) [inline]Set new coordinates for the vector from v. Returns reference to self.

See also:

getValue()

SbVec4s & SbVec4s::setValue (short x, short y, short z, short w) [inline]Set new coordinates for the vector. Returns reference to self.

getValue()

SbVec4s & SbVec4s::setValue (const SbVec4s & v) [inline]Constructs an SbVec4s instance with initial values from the vector v.

SbVec4s & SbVec4s::setValue (const SbVec4us & v)Sets this vector to the unsigned short integer precision vector v, converting the vector to a short integer precision vector.

SbVec4s & SbVec4s::setValue (const SbVec4b & v)Sets this vector to the 8-bit integer precision vector v, converting the vector to an short integer precision vector.

SbVec4s & SbVec4s::setValue (const SbVec4i32 & v)Sets this vector to the unsigned 32-bit integer precision vector v, converting the vector to an short integer precision vector.

const short * SbVec4s::getValue (void) const [inline]Returns a pointer to an array of four short integers containing the x, y, z and w coordinates of the vector.

setValue()

void SbVec4s::getValue (short & x, short & y, short & z, short & w) const [inline]Returns the x, y, z and w coordinates of the vector.

short & SbVec4s::operator[] (int i) [inline]Index operator. Returns modifiable x, y, z or w coordinate of the vector.

const short & SbVec4s::operator[] (int i) const [inline]Index operator. Returns non-modifiable x, y, z or w coordinate of the vector.

int32_t SbVec4s::dot (const SbVec4s & v) const [inline]Calculates and returns the result of taking the dot product of this vector and v.

void SbVec4s::negate (void) [inline]Negate the vector (i.e. point it in the opposite direction)

SbVec4s & SbVec4s::operator*= (int d) [inline]Multiply components of vector with scalar value d. Returns reference to self.

SbVec4s & SbVec4s::operator*= (double d)Multiply components of vector with value d. Returns reference to self.

SbVec4s & SbVec4s::operator/= (int d) [inline]Divides components of vector with scalar value d. Returns reference to self.

SbVec4s & SbVec4s::operator/= (double d) [inline]Divides components of vector with scalar value d. Returns reference to self.

SbVec4s & SbVec4s::operator+= (const SbVec4s & v) [inline]Adds this vector and vector u. Returns reference to self.

SbVec4s & SbVec4s::operator-= (const SbVec4s & v) [inline]Subtracts v from this vector. Returns reference to self.

SbVec4s SbVec4s::operator- (void) const [inline]Non-destructive negation operator. Returns a new SbVec4s instance which points in the opposite direction of this vector.
