The SbVec2d class is a 2 dimensional vector with double precision floating point coordinates.
This vector class is used by many other classes in Coin. It provides storage for a vector in 2 dimensions aswell as simple floating point arithmetic operations on this vector.
SbVec2d::SbVec2d | ( | void | ) | [inline] |
The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().
SbVec2d::SbVec2d | ( | const double | v[2] | ) | [inline] |
Constructs an SbVec2d instance with initial values from v.
SbVec2d::SbVec2d | ( | double | x, | |
double | y | |||
) | [inline] |
Constructs an SbVec2d instance with the initial vector endpoints from x and y.
SbVec2d::SbVec2d | ( | const SbVec2f & | v | ) | [inline, explicit] |
SbVec2d::SbVec2d | ( | const SbVec2b & | v | ) | [inline, explicit] |
SbVec2d::SbVec2d | ( | const SbVec2s & | v | ) | [inline, explicit] |
SbVec2d::SbVec2d | ( | const SbVec2i32 & | v | ) | [inline, explicit] |
SbVec2d & SbVec2d::setValue | ( | const double | v[2] | ) | [inline] |
Set new x and y coordinates for the vector from v. Returns reference to self.
SbVec2d & SbVec2d::setValue | ( | double | x, | |
double | y | |||
) | [inline] |
Set new x and y coordinates for the vector. Returns reference to self.
Sets the value from an SbVec2f instance. Returns reference to itself.
Sets the value from an SbVec2b instance. Returns reference to itself.
Sets the value from an SbVec2s instance. Returns reference to itself.
Sets the value from an SbVec2i32 instance. Returns reference to itself.
const double * SbVec2d::getValue | ( | void | ) | const [inline] |
Returns a pointer to an array of two double containing the x and y coordinates of the vector.
void SbVec2d::getValue | ( | double & | x, | |
double & | y | |||
) | const [inline] |
Returns the x and y coordinates of the vector.
double & SbVec2d::operator[] | ( | int | i | ) | [inline] |
Index operator. Returns modifiable x or y coordinate.
const double & SbVec2d::operator[] | ( | int | i | ) | const [inline] |
Index operator. Returns x or y coordinate.
SbBool SbVec2d::equals | ( | const SbVec2d & | 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.
double SbVec2d::dot | ( | const SbVec2d & | v | ) | const [inline] |
Calculates and returns the result of taking the dot product of this vector and v.
double SbVec2d::length | ( | void | ) | const |
Return length of vector.
double SbVec2d::normalize | ( | void | ) |
Normalize the vector to unit length. Return value is the original length of the vector before normalization.
void SbVec2d::negate | ( | void | ) | [inline] |
Negate the vector (i.e. point it in the opposite direction).
SbVec2d & SbVec2d::operator*= | ( | double | d | ) | [inline] |
Multiply components of vector with value d. Returns reference to self.
SbVec2d & SbVec2d::operator/= | ( | double | d | ) | [inline] |

Adds this vector and vector u. Returns reference to self.
Subtracts vector u from this vector. Returns reference to self.
SbVec2d SbVec2d::operator- | ( | void | ) | const [inline] |
void SbVec2d::print | ( | FILE * | fp | ) | const |
