GfVec4h GfCompDiv	(	GfVec4h const &	v1,
		GfVec4h const &	v2
	)

inline

Returns component-wise quotient of vectors v1 and v2.

Definition at line 358 of file vec4h.h.

GfVec4h GfCompMult	(	GfVec4h const &	v1,
		GfVec4h const &	v2
	)

inline

Returns component-wise multiplication of vectors v1 and v2.

Definition at line 347 of file vec4h.h.

GfHalf GfDot	(	GfVec4h const &	v1,
		GfVec4h const &	v2
	)

inline

Returns the dot (inner) product of two vectors.

Definition at line 369 of file vec4h.h.

GfVec4h GfGetComplement	(	GfVec4h const &	a,
		GfVec4h const &	b
	)

inline

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

That is:

* a - a.GetProjection(b)

*

Definition at line 414 of file vec4h.h.

GfHalf GfGetLength ( GfVec4h const & v )

inline

Returns the geometric length of v.

Definition at line 376 of file vec4h.h.

GfVec4h GfGetNormalized	(	GfVec4h const &	v,
		GfHalf	eps = `0.001`
	)

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 394 of file vec4h.h.

GfVec4h GfGetProjection	(	GfVec4h const &	a,
		GfVec4h const &	b
	)

inline

Returns the projection of a onto b.

That is:

* b * (a * b)

*

Definition at line 404 of file vec4h.h.

bool GfIsClose	(	GfVec4h const &	v1,
		GfVec4h 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 422 of file vec4h.h.

GfHalf GfNormalize	(	GfVec4h *	v,
		GfHalf	eps = `0.001`
	)

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.
