GF_API bool | GfFindClosestPoints (const GfLine &line, const GfLineSeg &seg, GfVec3d *p1=nullptr, GfVec3d *p2=nullptr, double *t1=nullptr, double *t2=nullptr) |
Computes the closets points on line and seg . | |
GF_API bool | GfFindClosestPoints (const GfLineSeg &seg1, const GfLineSeg &seg2, GfVec3d *p1=nullptr, GfVec3d *p2=nullptr, double *t1=nullptr, double *t2=nullptr) |
Computes the closets points on two line segments, seg1 and seg2 . | |
GF_API std::ostream & | operator<< (std::ostream &, const GfLineSeg &) |
Output a GfLineSeg. | |

) |
Computes the closets points on line
and seg
.
The two points are returned in p1
and p2
. The parametric distances of p1
and p2
along the line and segment are returned in t1
and t2
.
This returns false
if the lines were close enough to parallel that no points could be computed; in this case, the other return values are undefined.
