how to do it? This is the full script that the test.las file to visualize it with mathplotlib. import numpy as np import laspy from mpl_toolkits.mplot3d import Axes3D import matplotlib.pyplot as plt input_las = laspy.file.File("test.las", mode="r") point_records = input_las.points.copy() lasScaleX = input_las.header.scale[0] lasOffsetX = input_las.header.offset[0] lasScaleY = input_las.header.scale[1] lasOffsetY = input_las.header.offset[1] lasScaleZ = input_las.header.scale[2] lasOffsetZ = input_las.header.offset[2] p_X = np.array((point_records['point']['X'] * lasScaleX) + lasOffsetX) p_Y = np.array((point_records['point']['Y'] * lasScaleY) + lasOffsetY) p_Z = np.
