Function Documentation

GfVec2f GfCompDiv ( GfVec2f const &  v1, GfVec2f const &  v2  )

inline

Returns component-wise quotient of vectors v1 and v2.

Definition at line 320 of file vec2f.h.

GfVec2f GfCompMult ( GfVec2f const &  v1, GfVec2f const &  v2  )

inline

Returns component-wise multiplication of vectors v1 and v2.

Definition at line 311 of file vec2f.h.

float GfDot ( GfVec2f const &  v1, GfVec2f const &  v2  )

inline

Returns the dot (inner) product of two vectors.

Definition at line 329 of file vec2f.h.

GfVec2f GfGetComplement ( GfVec2f const &  a, GfVec2f const &  b  )

inline

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

a - a.GetProjection(b)

Definition at line 374 of file vec2f.h.

float GfGetLength ( GfVec2f const &  v )

inline

Returns the geometric length of v.

Definition at line 336 of file vec2f.h.

GfVec2f GfGetNormalized ( GfVec2f 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 354 of file vec2f.h.

GfVec2f GfGetProjection ( GfVec2f const &  a, GfVec2f const &  b  )

inline

Returns the projection of a onto b. That is:

b * (a * b)

Definition at line 364 of file vec2f.h.

bool GfIsClose ( GfVec2f const &  v1, GfVec2f 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 382 of file vec2f.h.

float GfNormalize ( GfVec2f *  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.

Definition at line 345 of file vec2f.h.

GF_API std::ostream& operator<<	(	std::ostream &	,
		GfVec2f const &
	)

Output a GfVec2f.
