GfVec4f GfCompDiv	(	GfVec4f const &	v1,
		GfVec4f const &	v2
	)

inline

Returns component-wise quotient of vectors v1 and v2.

Definition at line 357 of file vec4f.h.

GfVec4f GfCompMult	(	GfVec4f const &	v1,
		GfVec4f const &	v2
	)

inline

Returns component-wise multiplication of vectors v1 and v2.

Definition at line 346 of file vec4f.h.

float GfDot	(	GfVec4f const &	v1,
		GfVec4f const &	v2
	)

inline

Returns the dot (inner) product of two vectors.

Definition at line 368 of file vec4f.h.

GfVec4f GfGetComplement	(	GfVec4f const &	a,
		GfVec4f const &	b
	)

inline

Returns the orthogonal complement of a.GetProjection(b).

That is:

* a - a.GetProjection(b)

*

Definition at line 413 of file vec4f.h.

float GfGetLength ( GfVec4f const & v )

inline

Returns the geometric length of v.

Definition at line 375 of file vec4f.h.

GfVec4f GfGetNormalized	(	GfVec4f const &	v,
		float	eps = `GF_MIN_VECTOR_LENGTH`
	)

inline

Returns a normalized (unit-length) vector with the same direction as v.

If the length of this vector is smaller than eps, the vector divided by eps is returned.

Definition at line 393 of file vec4f.h.

GfVec4f GfGetProjection	(	GfVec4f const &	a,
		GfVec4f const &	b
	)

inline

Returns the projection of a onto b.

That is:

* b * (a * b)

*

Definition at line 403 of file vec4f.h.

bool GfIsClose	(	GfVec4f const &	v1,
		GfVec4f const &	v2,
		double	tolerance
	)

inline

Tests for equality within a given tolerance, returning true if the length of the difference vector is less than or equal to tolerance.

Definition at line 421 of file vec4f.h.

float GfNormalize	(	GfVec4f *	v,
		float	eps = `GF_MIN_VECTOR_LENGTH`
	)

inline

Normalizes *v in place to unit length, returning the length before normalization.

If the length of *v is smaller than eps then *v is set to *v/eps. The original length of *v is returned.
