This vector class is used by many other classes in Coin. It provides storage for a vector in 2 dimensions as well as simple floating point arithmetic operations on this vector. See also SbVec2s, SbVec2d, SbVec3s, SbVec3f, SbVec3d, SbVec4f, SbVec4d. Constructor & Destructor Documentation SbVec2f::SbVec2f (void) [inline] The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue(). SbVec2f::SbVec2f (const float v[2]) [inline] Constructs an SbVec2f instance with initial values from v. SbVec2f::SbVec2f (float x, float y) [inline] Constructs an SbVec2f instance with the initial vector endpoints from x and y. SbVec2f::SbVec2f (const SbVec2d & v) [inline], [explicit] Constructs an instance from an SbVec2d instance. Since Coin 2.5 SbVec2f::SbVec2f (const SbVec2b & v) [inline], [explicit] Constructs an instance from an SbVec2d instance. Since Coin 2.5 SbVec2f::SbVec2f (const SbVec2s & v) [inline], [explicit] Constructs an instance from an SbVec2d instance. Since Coin 2.5 SbVec2f::SbVec2f (const SbVec2i32 & v) [inline], [explicit] Constructs an instance from an SbVec2d instance. Since Coin 2.5 Member Function Documentation SbVec2f & SbVec2f::setValue (const float v[2]) [inline] Set new x and y coordinates for the vector from v. Returns reference to self. See also getValue(). SbVec2f & SbVec2f::setValue (float x, float y) [inline] Set new x and y coordinates for the vector. Returns reference to self. See also getValue(). SbVec2f & SbVec2f::setValue (const SbVec2d & v) Sets the value from an SbVec2d instance. Since Coin 2.5 SbVec2f & SbVec2f::setValue (const SbVec2b & v) Sets the value from an SbVec2b instance. Since Coin 2.5 SbVec2f & SbVec2f::setValue (const SbVec2s & v) Sets the value from an SbVec2s instance. Since Coin 2.5 SbVec2f & SbVec2f::setValue (const SbVec2i32 & v) Sets the value from an SbVec2i32 instance. Since Coin 2.5 const float * SbVec2f::getValue (void) const [inline] Returns a pointer to an array of two floats containing the x and y coordinates of the vector. See also setValue(). void SbVec2f::getValue (float & x, float & y) const [inline] Returns the x and y coordinates of the vector. See also setValue(). float & SbVec2f::operator[] (int i) [inline] Index operator. Returns modifiable x or y coordinate. See also getValue() and setValue(). const float & SbVec2f::operator[] (int i) const [inline] Index operator. Returns x or y coordinate. See also getValue(). float SbVec2f::dot (const SbVec2f & v) const [inline] Calculates and returns the result of taking the dot product of this vector and v. SbBool SbVec2f::equals (const SbVec2f & 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. float SbVec2f::length (void) const Return length of vector. float SbVec2f::sqrLength (void) const [inline] Returns the square of the length of the vector. Since Coin 2.5 void SbVec2f::negate (void) [inline] Negate the vector (i.e. point it in the opposite direction). float SbVec2f::normalize (void) Normalize the vector to unit length. Return value is the original length of the vector before normalization. SbVec2f & SbVec2f::operator*= (float d) [inline] Multiply components of vector with value d. Returns reference to self. SbVec2f & SbVec2f::operator/= (float d) [inline] Divides components of vector with value d. Returns reference to self. SbVec2f & SbVec2f::operator+= (const SbVec2f & v) [inline] Adds this vector and vector u. Returns reference to self. SbVec2f & SbVec2f::operator-= (const SbVec2f & v) [inline] Subtracts vector u from this vector. Returns reference to self. SbVec2f SbVec2f::operator- (void) const [inline] Non-destructive negation operator. Returns a new SbVec2f instance which points in the opposite direction of this vector. See also negate(). SbString SbVec2f::toString () const Return a string representation of this object SbBool SbVec2f::fromString (const SbString & str) Convert from a string representation, return whether this is a valid conversion void SbVec2f::print (FILE * fp) const Dump the state of this object to the fp file stream. Only works in debug version of library, method does nothing in an optimized build. Friends And Related Symbol Documentation SbVec2f operator* (const SbVec2f & v, float d) [related] Returns an SbVec2f instance which is the components of vector v multiplied with d.
