Introduction

vtkPolyData is a dataset that represents a geometric structure consisting of vertices, lines, polygons, and/or strips.

Methods

buildCells

Create data structure that allows random access of cells.

buildLinks

Create upward links from points to cells that use each point. Enables topologically complex queries.

Argument	Type	Required	Description
initialSize	Number	Yes

extend

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

getCell

If you know the type of cell, you may provide it to improve performances.

Argument	Type	Required	Description
cellId	Number	Yes
cellHint		Yes

getCellEdgeNeighbors

Get the neighbors at an edge.

Argument	Type	Required	Description
cellId	Number	Yes	The Id of the cell.
point1	Vector3	Yes	The first point coordinate.
point2	Vector3	Yes	The second point coordinate.

getCellPoints

Get a list of point ids that define a cell.

Argument	Type	Required	Description
cellId	Number	Yes	The Id of the cell.

getCellType

Get the type of the cell

Argument	Type	Required	Description
cellId	Number	Yes	The Id of the cell.

getCells

Get the cell array defining cells.

getLines

Get the cell array defining lines.

getLinks

Get the links between points and cells.

getMaxCellSize

Get the maximum cell size. Returns 0 if there is no cell.

getNumberOfCells

Determine the number of cells composing the polydata.

getNumberOfLines

Determine the number of lines composing the polydata.

getNumberOfPoints

Determine the number of points composing the polydata.

getNumberOfPolys

Determine the number of polys composing the polydata.

getNumberOfStrips

Determine the number of strips composing the polydata.

getNumberOfVerts

Determine the number of vertices composing the polydata.

getPointCells

Topological inquiry to get cells using point.

Argument	Type	Required	Description
ptId		Yes

getPolys

Get the cell array defining polys.

getStrips

Get the cell array defining strips.

getVerts

Get the cell array defining vertices. If there are no vertices, an empty array will be returned (convenience to simplify traversal).

initialize

Empty the cells and initialize the point set.

newInstance

Method used to create a new instance of vtkPolyData.

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

setLines

Set the cell array defining lines.

Argument	Type	Required	Description
lines	vtkCellArray	Yes	The cell array defining lines.

setPolys

Set the cell array defining polys.

Argument	Type	Required	Description
polys	vtkCellArray	Yes	The cell array defining polys.

setStrips

Set the cell array defining strips.

Argument	Type	Required	Description
strips	vtkCellArray	Yes	The cell array defining strips.

setVerts

Set the cell array defining vertices.

Argument	Type	Required	Description
verts	vtkCellArray	Yes	The cell array defining vertices.
