◆ GfGetComplement()
Returns the orthogonal complement of a.GetProjection(b)
.
That is:
Definition at line 357 of file vec2d.h.
◆ GfGetLength()
double GfGetLength |
( |
GfVec2d const & |
v | ) |
|
|
inline |
Returns the geometric length of v
.
Definition at line 319 of file vec2d.h.
◆ GfGetNormalized()
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 337 of file vec2d.h.
◆ GfGetProjection()
Returns the projection of a
onto b
.
That is:
Definition at line 347 of file vec2d.h.
◆ GfIsClose()

GfVec2d 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 365 of file vec2d.h.
◆ GfNormalize()
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.
