SbVec2s::SbVec2s | ( | void | ) |
The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().
SbVec2s::SbVec2s | ( | const short | v[2] | ) |
Constructs an SbVec2s instance with initial values from v.
SbVec2s::SbVec2s | ( | const short | x, | |
const short | y | |||
) |
Constructs an SbVec2s instance with the initial vector endpoints from x and y.
int32_t SbVec2s::dot | ( | const SbVec2s & | v | ) | const |
Calculates and returns the result of taking the dot product of this vector and v.
const short * SbVec2s::getValue | ( | void | ) | const |
Returns a pointer to an array of two floats containing the x and y coordinates of the vector.
void SbVec2s::getValue | ( | short & | x, | |
short & | y | |||
) | const |
void SbVec2s::negate | ( | void | ) |
Negate the vector (i.e. point it in the opposite direction).
SbVec2s & SbVec2s::setValue | ( | const short | v[2] | ) |
SbVec2s & SbVec2s::setValue | ( | short | x, | |

const short & SbVec2s::operator[] | ( | const int | i | ) | const |
SbVec2s & SbVec2s::operator *= | ( | int | d | ) |
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/= | ( | int | d | ) |
Divides components of vector with value d. Returns reference to self.
SbVec2s & SbVec2s::operator/= | ( | double | d | ) |
Divides components of vector with value d. Returns reference to self.
Adds this vector and vector u. Returns reference to self.
Subtracts vector u from this vector. Returns reference to self.
SbVec2s SbVec2s::operator- | ( | void | ) | const |
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.
Returns an SbVec2s instance which is the components of vector v multiplied with d.
Returns an SbVec2s instance which is the components of vector v multiplied with d.
Returns an SbVec2s instance which is the components of vector v multiplied with d.
Returns an SbVec2s instance which is the components of vector v multiplied with d.
Returns an SbVec2s instance which is the components of vector v divided on d.
Returns an SbVec2s instance which is the components of vector v divided on d.
Returns an SbVec2s instance which is the sum of vectors v1 and v2.
Returns an SbVec2s instance which is vector v2 subtracted from vector v1.
Returns 1 if v1 and v2 are equal, 0 otherwise.
Returns 1 if v1 and v2 are not equal, 0 if they are equal.
