Purpose

The purpose of MLBaseToVTKPolyData is to provide a conversion from point- or vector-like ML Base objects to a vtkPoints/vtkPolyData object. Supported Base objects are XMarkerContainers, XMarkerLists, VectorLists and PointLists.

Usage

Connect a XMarkerContainer, XMarkerList, VectorList or PointList object to the input, select the VTK Data Type for the list and an Object Type and connect the vtkPoints object at the module output to the module which needs the vtkPoints object.

Input Fields

inputList

name: inputList, type: MLBase

Connect a XMarkerContainer, XMarkerList, VectorList or PointList object to the input.

Output Fields

outputPolyData

name: outputPolyData, type: MLBase

The output provides a vtkPoints/vtkPolyData object. The number of points depends on the connected input Base object and the data type from the DataType parameter.

Data Type To Unsigned Char

name: dataTypeToUnsignedChar, type: Trigger

Selects the data type Unsigned Char (=3)

Data Type To Short

name: dataTypeToShort, type: Trigger

Selects the data type Short (=4)

Data Type To Unsigned Short

name: dataTypeToUnsignedShort, type: Trigger

Selects the data type Unsigned Short (=5)

Data Type To Int

name: dataTypeToInt, type: Trigger

Data Type To Float

name: dataTypeToFloat, type: Trigger

Selects the data type Float (=10)

Data Type To Double

name: dataTypeToDouble, type: Trigger

Selects the data type Double (=11)

Number Of Points

name: numberOfPoints, type: Integer, default: 0

This read-only field shows the number of points in the connected input Base object and the output vtkPoints / vtkPolyData object.

Status

name: status, type: String, default: Input connection open(0 elements)

Shows modules state

Object Type

name: objectType, type: Enum, default: Points

Allows to set the cell type of the output vtkPolyData object

Values:

Title	Name	Description
Points	Points	The cell type VTK_POLY_VERTEX is used, resulting in a set of points.
Open Polyline	Open Polyline	The cell type VTK_POLY_LINE is used. Consecutive points are connected by a line, resulting in an open polyline.
Closed Polyline	Closed Polyline	The cell type VTK_POLY_LINE is used. Consecutive points are connected by a line. Additionally, the last point is connected with the first point, resulting in a closed polyline.
Polygon	Polygon	The cell type VTK_POLYGON is used. Consecutive points are connected by a line. Additionally, the last point is connected with the first point, resulting in a closed polygon. Note: there is no check for convexity!
