Run: ``python examples/make_sample.py`` -> writes ``examples/sample.bin`` (a real
lidar sweep of Perlin-noise terrain with trees and patchy grass — ground, natural
obstacles and vegetation, enough to try every segmenter, ground detection and the
voxel mode). Open it with ``toaster examples/sample.bin``.
The same generator (``toaster.demo_scene``) backs ``toaster demo`` / typing "demo"
into the Open dialog, which builds a fresh scene on the fly with a random seed
instead of reading this fixed file.
