Examples

Loading a LAZ file

import startinpy

dt = startinpy.DT()
dt.read_las("/home/elvis/myfile.laz")
print("# vertices:", dt.number_of_vertices())

Exporting the DT to QGIS (GeoJSON)

import startinpy
import numpy as np

#-- generate 100 points randomly in the plane
rng = np.random.default_rng(seed=42)
pts = rng.random((100, 3))
dt = startinpy.DT()
dt.insert(pts)
dt.write_geojson("/home/elvis/myfile.geojson")

Plotting the DT with matplotlib

import startinpy
import numpy as np

#-- generate 100 points randomly in the plane
rng = np.random.default_rng(seed=42)
pts = rng.random((100, 3))
pts = pts * 100 #-- scale to [0, 100]
t = startinpy.DT()
t.insert(pts)
pts = t.points
trs = t.triangles
#-- plot
import matplotlib.pyplot as plt
plt.triplot(pts[:,0], pts[:,1], trs)
#-- the vertex "0" shouldn't be plotted, so start at 1
plt.plot(pts[1:,0], pts[1:,1], 'o')
plt.show()
