GfVec3d GfCompDiv ( GfVec3d const &  v1, GfVec3d const &  v2  )

inline

Returns component-wise quotient of vectors v1 and v2.

Definition at line 358 of file vec3d.h.

GfVec3d GfCompMult ( GfVec3d const &  v1, GfVec3d const &  v2  )

inline

Returns component-wise multiplication of vectors v1 and v2.

Definition at line 348 of file vec3d.h.

GfVec3d GfCross ( GfVec3d const &  v1, GfVec3d const &  v2  )

inline

Returns the cross product of v1 and v2.

Definition at line 440 of file vec3d.h.

double GfDot ( GfVec3d const &  v1, GfVec3d const &  v2  )

inline

Returns the dot (inner) product of two vectors.

Definition at line 368 of file vec3d.h.

GfVec3d GfGetComplement ( GfVec3d const &  a, GfVec3d const &  b  )

inline

Returns the orthogonal complement of a.GetProjection(b). That is:

a - a.GetProjection(b)

Definition at line 413 of file vec3d.h.

double GfGetLength ( GfVec3d const &  v )

inline

Returns the geometric length of v.

Definition at line 375 of file vec3d.h.

GfVec3d GfGetNormalized ( GfVec3d const &  v, double  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 vec3d.h.

GfVec3d GfGetProjection ( GfVec3d const &  a, GfVec3d const &  b  )

inline

Returns the projection of a onto b. That is:

b * (a * b)

Definition at line 403 of file vec3d.h.

bool GfIsClose ( GfVec3d const &  v1, GfVec3d 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 vec3d.h.

double GfNormalize ( GfVec3d *  v, double  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.

Definition at line 384 of file vec3d.h.

GF_API bool GfOrthogonalizeBasis	(	GfVec3d *	tx,
		GfVec3d *	ty,
		GfVec3d *	tz,

	)

GF_API GfVec3d GfSlerp	(	double	alpha,
		GfVec3d const &	v0,
		GfVec3d const &	v1
	)

Spherical linear interpolation in three dimensions.

GF_API std::ostream& operator<<	(	std::ostream &	,
		GfVec3d const &
	)

Output a GfVec3d.

GfVec3d operator^ ( GfVec3d const &  v1, GfVec3d const &  v2  )

inline

Returns the cross product of v1 and v2.
