Function Documentation

GF_API bool GfFindClosestPoints ( const GfLine2d l1,
const GfLine2d l2,
GfVec2d p1 = nullptr,
GfVec2d p2 = nullptr,
double *  t1 = nullptr,
double *  t2 = nullptr 
)

Computes the closets points between two lines.

The two points are returned in p1 and p2. The parametric distance of each point on the lines is 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.
