saveAsCsv

public static void saveAsCsv(ArrayList<ArrayList<Long>> data,
 String[] headers,
 String path)
                      throws IOException

Stores each list in data as a column in csv.

Parameters:

data - ArrayList of multiple ArrayLists to write as columns to csv. Must have same sizes.

headers - What headers should columns have.

path - Path to file to write in.

Throws:

IOException - If FileWriter couldn't open the file.

createRandomFacet

public static MeshFacet createRandomFacet(int numPoints,
 float lowerBound,
 float upperBound)

Creates facet with a specified number of vertexes in a given range. Adapted from SpatialDataProvider

Parameters:

numPoints - Number of vertexes of the MeshFacet, must be divisible by 3.

lowerBound - Lowest x/y/z value of a randomly created vertex.

upperBound - Highest x/y/z value of a randomly created vertex.

Returns:

MeshFacet
