Introduction

vtkLine is a cell which representant a line. It contains static method to make some computations directly link to line.

Methods

evaluateLocation

Determine the global coordinates x' and parametric coordinates pcoords' in the cell.

evaluateOrientation

Determine the global orientation q' and parametric coordinates pcoords' in the cell. Use slerp to interpolate orientation Returns wether the orientation has been set in `q'

extend

Method used to decorate a given object (publicAPI+model) with vtkLine characteristics.

Argument	Type	Required	Description
publicAPI		Yes	object on which methods will be bounds (public)
model		Yes	object on which data structure will be bounds (protected)
initialValues	ILineInitialValues	No	(default: {})

getCellDimension

Get the topological dimensional of the cell (0, 1, 2 or 3).

getOrientations

Get the list of orientations (a list of quat) for each point of the line. Can be null if the line is not oriented

intersectWithLine

Compute the intersection point of the intersection between line and line defined by p1 and p2. tol Tolerance use for the position evaluation x is the point which intersect triangle (computed in function) pcoords parametric coordinates (computed in function) A javascript object is returned :

{
  evaluation: define if the line has been intersected or not
  subId: always set to 0
  t: tolerance of the intersection
}

Argument	Type	Required	Description
p1	Vector3	Yes	The first point coordinate.
p2	Vector3	Yes	The second point coordinate.
tol	Number	Yes	The tolerance to use.
x	Vector3	Yes	The point which intersect triangle.
pcoords	Vector3	Yes	The parametric coordinates.

newInstance

Method used to create a new instance of vtkLine.

Argument	Type	Required	Description
initialValues	ILineInitialValues	No	for pre-setting some of its content

setOrientations

Argument	Type	Required	Description
orientations		Yes	The list of orientation per point of the centerline
