triangulatePolygons

Triangulate Polygons

Produces a new polygon layer with only triangular polygons. Each polygon from the input layer is represented as a set of triangles. If the input does not have overlapping polygons, the output will not have overlapping triangles.

Inputs:

A polygon layer.

Outputs:

New Polygon layer
- Each polygon from the input layer is represented as a set of triangles
- The attrributes of the input polygons are preserved
- The existing holes in the input polygons are preserved.
- The "ET_ID" field of the output is populated with the feature ID of the input polygons

Examples:

Input Layer

Parameters

Expression	Explanation
Function Name	TriangulatePolygons
<input dataset>	A String representing the input layer. Must be of Polygon type.
<output dataset>	A String - the full name of the output layer.

Running the function

ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETGeo Wizards\ETGWRun.exe")

Language	Syntax
Python	subprocess.call([ETGWPath, "TriangulatePolygons", "input dataset", "output dataset"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "TriangulatePolygons" "input dataset" "output dataset"
.NET using ETGWOutX.dll	TriangulatePolygons(input dataset, output dataset)
ArcPy	arcpy.TriangulatePolygons(input dataset, "output dataset")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
