Detailed Description

General purpose 2D vector class.

Representation of a 2D vector, defining operations to access, modify and perform calculations on 2D vectors. This class uses double precision floating-point numbers for represent its data, and in its operations. There are seperate similar classes for 3D and 4D vectors, CSIBCVector3Dd and CSIBCVector4Dd, respectively, which also use double precision.

Furthermore, there is another set of vector classes which use single precision floating-point numbers, CSIBCVector2D, CSIBCVector3D and CSIBCVector4D for 2D, 3D and 4D vectors respectively. Quaternions represented as 4D vectors are also available in CSIBCQuaternion and CSIBCQuaterniond with single precision and double precision, repspectively.

) [friend]

Determines whether all corresponding components of the in_vct1 and in_vct2 are equal. Since this method uses floating-point comparison, a threshhold value of in_dEpsilon is used for equality comparison.

Parameters:
in_vct1  First vector for equality comparison.
in_vct2  Second vector for equality comparison.
in_dEpsilon  Floating-point comparison error range. Defaults to PICO_EPS.
Returns:
bool true if the vectors are equal, false otherwise.

double GetDot ( const CSIBCVector2Dd &  in_vct1,
const CSIBCVector2Dd &  in_vct2  
) [friend]

Computes the dot product between the vectors in_vct1 and in_vct2.

Parameters:
in_vct1  First vector in the dot product.
in_vct2  Second vector in the dot product.
Returns:
double The dot product between in_vct1 and in_vct2.

double GetDistance ( const CSIBCVector2Dd &  in_pnt1,
const CSIBCVector2Dd &  in_pnt2  
) [friend]

Computes the distance between two points in 2D space given by in_pnt1 and in_pnt2.

Parameters:
in_pnt1  Starting point for distance calculation.
in_pnt2  Ending point for distance calculation.
Returns:
double The scalar distance between the two points, in 2D space.

double GetSquaredDistance ( const CSIBCVector2Dd &  in_pnt1,
const CSIBCVector2Dd &  in_pnt2  
) [friend]

Computes the squared distance between two points in 2D space given by in_pnt1 and in_pnt2.

Parameters:
in_pnt1  Starting point for distance calculation.
