Function Documentation

◆ SplitHomoVector() [1/2]

template<typename PointParamVector , typename PointVector >

void c3d::SplitHomoVector	(	const PointParamVector &	hList,
		PointVector &	uvList
	)

Separation of coordinates and weights.

Separation of coordinates and weights.
Additional coordinate of a point (weight) is introduced for the convenience of working with non-uniform rational splines.

◆ SplitHomoVector() [2/2]

template<typename PointParamVector , typename PointVector , typename ParamVector >

void c3d::SplitHomoVector	(	const PointParamVector &	hList,
		PointVector &	uvList,
		ParamVector &	tList
	)

Separation of coordinates and weights.

Separation of coordinates and weights.
Additional coordinate of a point (weight) is introduced for the convenience of working with non-uniform rational splines.

◆ MulMatrix()

void MulMatrix	(	const MbMatrix &	m1,
		const MbMatrix &	m2,
		MbMatrix &	res
	)

Multiply matrices.

Multiply m1 matrix by m2 matrix (instead of res = m1 * m2).

Parameters

[in]	m1,m2	- Initial matrices.
[out]	res	- The required matrix.

◆ Angle2Vectors()

double Angle2Vectors	(	const MbVector &	v1,
		const MbVector &	v2
	)

inline

Calculate minimal angle between two vectors.

Calculate angle between two vectors (-pi ... pi) Returns signed result:
<0 to the left of vector v1
>0 to the right of vector v2

Note: Normalization of vectors is not required
