Clip this line using scalar value provided. Like contouring, except that it cuts the line to produce other lines.

Line-line intersection. Intersection has to occur within [0,1] parametric coordinates and with specified tolerance.
Implements vtkCell.

double | p2[3], | |||
double | x1[3], | |||

double & | u, | |||

) | [static] |
Performs intersection of two finite 3D lines. An intersection is found if the projection of the two lines onto the plane perpendicular to the cross product of the two lines intersect. The parameters (u,v) are the parametric coordinates of the lines at the position of closest approach.
static double vtkLine::DistanceToLine | ( | double | x[3], | |
double | p1[3], | |||
double | p2[3], | |||
double & | t, | |||
double | closestPoint[3] | |||
) | [static] |
Compute the distance of a point x to a finite line (p1,p2). The method computes the parametric coordinate t and the point location on the line. Note that t is unconstrained (i.e., it may lie outside the range [0,1]) but the closest point will lie within the finite line [p1,p2]. Also, the method returns the distance squared between x and the line (p1,p2).
static double vtkLine::DistanceToLine | ( | double | x[3], | |
double | p1[3], | |||
double | p2[3] | |||
) | [static] |
Determine the distance of the current vertex to the edge defined by the vertices provided. Returns distance squared. Note: line is assumed infinite in extent.

double | l1[3], | |||

double | closestPt1[3], | |||
double | closestPt2[3], | |||
double & | t1, | |||
double & | t2 | |||
) | [static] |
Computes the shortest distance squared between two infinite lines, each defined by a pair of points (l0,l1) and (m0,m1). Upon return, the closest points on the two line segments will be stored in closestPt1 and closestPt2. Their parametric coords (-inf <= t0, t1 <= inf) will be stored in t0 and t1. The return value is the shortest distance squared between the two line-segments.

double | closestPt1[3], | |||
double | closestPt2[3], | |||
double & | t1, | |||
double & | t2 | |||
) | [static] |
Computes the shortest distance squared between two finite line segments defined by their end points (l0,l1) and (m0,m1). Upon return, the closest points on the two line segments will be stored in closestPt1 and closestPt2. Their parametric coords (0 <= t0, t1 <= 1) will be stored in t0 and t1. The return value is the shortest distance squared between the two line-segments.
