Introduction

vtkQuad is a cell which represents a quadrilateral. It may contain static methods to make some computations directly link to quads.

Methods

evaluateLocation

Determine global coordinate (x]) from subId and parametric coordinates.

Argument	Type	Required	Description
pcoords	Vector3	Yes	The parametric coordinates.
x	Vector3	Yes	The x point coordinate.
weights	Array[Number]	Yes	The number of weights.

extend

Method used to decorate a given object (publicAPI+model) with vtkQuad 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	IQuadInitialValues	No	(default: {})

getCellDimension

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

intersectWithLine

Compute the intersection point of the intersection between quad 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 triangle has been intersected or not
   subId: always set to 0
   t: parametric coordinate along the line.
   betweenPoints: Define if the intersection is between input points
}

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 vtkQuad.

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