Introduction

vtkAppendPolyData - append one or more polygonal datasets together

vtkAppendPolyData is a filter that appends one of more polygonal datasets into a single polygonal dataset. All geometry is extracted and appended, but point and cell attributes (i.e., scalars, vectors, normals) are extracted and appended only if all datasets have the point and/or cell attributes available. (For example, if one dataset has point scalars but another does not, point scalars will not be appended.)

Usage

Provide the first input to the filter via the standard setInput(Data/Connection) methods. Any additional inputs can be provided via the addInput(Data/Connection) methods. When only a single input is provided, it is passed through as is to the output.

const cone = vtkConeSource.newInstance();
const cylinder = vtkCylinderSource.newInstance();

const appendPolyData = vtkAppendPolyData.newInstance();
appendPolyData.setInputConnection(cone.getOutputPort());
appendPolyData.addInputConnection(cylinder.getOutputPort());

const appendedData = appendPolyData.getOutputData();
