Use laspy to create las file from scratch without opening an existing las file first

I have found instructions for creating a las file by opening an existing file, modifying it, then re-saving it.

This re-uses the headers from the original file.

But how do I create a new file from scratch without loading another in the first place? I cannot see any documentation on the required format for the file, points, or headers.

I only need the bare minimum: x,y,z position for each point.

Here is how I assumed it might work...

import numpy as npimport laspyimport laspy.headerimport laspy.filepoints = []#x,y,z valuespoints.append([0,0,10])points.append([1,0,10])points.append([2,0,11])header = laspy.header.Header()outFile = laspy.file.File("./output.las", mode = "w", header = header)outFile.points = np.array(points)outFile.close()This fails with:

-> outFile.points = np.array(points)/laspy/file.py-> self._writer.set_points(new_points)laspy/base.py-> self.data_provider._pmap[:] = points[:]ValueError: could not broadcast input array from shape (3,3) into shape (3)Could anyone kindly point to some sample code or tips to get this working?
