◆ LineSegmentsMinimumDistance()

double cloudViewer::utility::IntersectionTest::LineSegmentsMinimumDistance ( const Eigen::Vector3d &  p0,
const Eigen::Vector3d &  p1,
const Eigen::Vector3d &  q0,
const Eigen::Vector3d &  q1 
)
static

Computes the minimum distance between two line segments. The first line segment is defined by 3D points

Parameters
p0and
p1,thesecond line segment is defined by 3D points
q0and
q1.This implementation is based on the description of David Eberly (https://www.geometrictools.com/Documentation/DistanceLine3Line3.pdf).

◆ LinesMinimumDistance()

double cloudViewer::utility::IntersectionTest::LinesMinimumDistance ( const Eigen::Vector3d &  p0,
const Eigen::Vector3d &  p1,
const Eigen::Vector3d &  q0,
const Eigen::Vector3d &  q1 
)
static

Computes the minimum distance between two lines. The first line is defined by 3D points

Parameters
p0and
p1,thesecond line is defined by 3D points
q0and
q1.The returned distance is negative if no minimum distance can be computed. This implementation is based on the description of Paul Bourke (http://paulbourke.net/geometry/pointlineplane/).
