Function Documentation

GF_API bool GfFindClosestPoints	(	const GfRay &	ray,
		const GfLine &	line,
		GfVec3d *	rayPoint = nullptr,
		GfVec3d *	linePoint = nullptr,
		double *	rayDistance = nullptr,
		double *	lineDistance = nullptr
	)

Computes the closest points between a ray and a line. The two points are returned in rayPoint and linePoint. The parametric distance of each point on the lines is returned in rayDistance and lineDistance.

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.

GF_API bool GfFindClosestPoints	(	const GfRay &	ray,
		const GfLineSeg &	seg,
		GfVec3d *	rayPoint = nullptr,
		GfVec3d *	segPoint = nullptr,
		double *	rayDistance = nullptr,
		double *	segDistance = nullptr
	)

Computes the closest points between a ray and a line segment. The two points are returned in rayPoint and segPoint. The parametric distance of each point is returned in rayDistance and segDistance.

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.

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

Output a GfRay using the format [(x y z) >> (x y z)].
