Function Documentation

GfVec2h GfCompDiv ( GfVec2h const &  v1,
GfVec2h const &  v2 
)
inline

Returns component-wise quotient of vectors v1 and v2.

Definition at line 326 of file vec2h.h.

GfVec2h GfCompMult ( GfVec2h const &  v1,
GfVec2h const &  v2 
)
inline

Returns component-wise multiplication of vectors v1 and v2.

Definition at line 317 of file vec2h.h.

GfHalf GfDot ( GfVec2h const &  v1,
GfVec2h const &  v2 
)
inline

Returns the dot (inner) product of two vectors.

Definition at line 335 of file vec2h.h.

GfVec2h GfGetComplement ( GfVec2h const &  a,
GfVec2h const &  b 
)
inline

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

That is:

* a - a.GetProjection(b)
*

Definition at line 380 of file vec2h.h.

GfHalf GfGetLength ( GfVec2h const &  v)
inline

Returns the geometric length of v.

Definition at line 342 of file vec2h.h.

GfVec2h GfGetNormalized ( GfVec2h 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 360 of file vec2h.h.

GfVec2h GfGetProjection ( GfVec2h const &  a,
GfVec2h const &  b 
)
inline

Returns the projection of a onto b.

That is:

* b * (a * b)
*

Definition at line 370 of file vec2h.h.

bool GfIsClose ( GfVec2h const &  v1,
GfVec2h 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 388 of file vec2h.h.

GfHalf GfNormalize ( GfVec2h 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.
