Detailed Description

The SbVec2s class is a 2 dimensional vector with short integer coordinates.

This vector class is used by many other classes in Coin. It provides storage for a vector in 2 dimensions as well as simple integer arithmetic operations.

Constructor & Destructor Documentation

SbVec2s::SbVec2s (void) [inline]

The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().

SbVec2s::SbVec2s (const short v[2]) [inline]

Constructs an SbVec2s instance with initial values from v.

SbVec2s::SbVec2s (short x, short y) [inline]

Constructs an SbVec2s instance with the initial vector endpoints from x and y.

SbVec2s::SbVec2s (const SbVec2us & v) [inline], [explicit]

Constructs an SbVec2s instance from the value in an SbVec2us instance.

setValue().

void SbVec2s::getValue (short & x, short & y) const [inline]

Returns the x and y coordinates of the vector.

int32_t SbVec2s::dot (SbVec2s v) const [inline]

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

void SbVec2s::negate (void) [inline]

Negate the vector (i.e. point it in the opposite direction).

SbVec2s & SbVec2s::operator*= (int d) [inline]

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

SbVec2s & SbVec2s::operator*= (double d)

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

SbVec2s & SbVec2s::operator+= (SbVec2s v) [inline]

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

SbVec2s & SbVec2s::operator-= (SbVec2s v) [inline]

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

SbVec2s SbVec2s::operator- (void) const [inline]

Non-destructive negation operator. Returns a new SbVec2s instance which points in the opposite direction of this vector.

negate().

SbString SbVec2s::toString () const

Return a string representation of this object

SbBool SbVec2s::fromString (const SbString & str)

Convert from a string representation, return wether this is a valid conversion

void SbVec2s::print (FILE * fp) const

Dump the state of this object to the file stream. Only works in debug version of library, method does nothing in an optimized compile.
