Function Documentation

GfVec4d GfCompDiv ( GfVec4d const &  v1, GfVec4d const &  v2  )

inline

Returns component-wise quotient of vectors v1 and v2.

Definition at line 350 of file vec4d.h.

GfVec4d GfCompMult ( GfVec4d const &  v1, GfVec4d const &  v2  )

inline

Returns component-wise multiplication of vectors v1 and v2.

Definition at line 339 of file vec4d.h.

double GfDot ( GfVec4d const &  v1, GfVec4d const &  v2  )

inline

Returns the dot (inner) product of two vectors.

Definition at line 361 of file vec4d.h.

GfVec4d GfGetComplement ( GfVec4d const &  a, GfVec4d const &  b  )

inline

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

a - a.GetProjection(b)

Definition at line 406 of file vec4d.h.

double GfGetLength ( GfVec4d const &  v )

inline

Returns the geometric length of v.

Definition at line 368 of file vec4d.h.

GfVec4d GfGetNormalized ( GfVec4d 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 386 of file vec4d.h.

GfVec4d GfGetProjection ( GfVec4d const &  a, GfVec4d const &  b  )

inline

Returns the projection of a onto b. That is:

b * (a * b)

Definition at line 396 of file vec4d.h.

bool GfIsClose ( GfVec4d const &  v1, GfVec4d 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 414 of file vec4d.h.

double GfNormalize ( GfVec4d *  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 377 of file vec4d.h.

GF_API std::ostream& operator<<	(	std::ostream &	,
		GfVec4d const &
	)

Output a GfVec4d.
