Point cloud level of detail: octree render, coarse to fine

Point Cloud Level of Detail in Python: Octrees, Frustum Culling, and Out-of-Core Rendering

A cloud bigger than your memory still spins at sixty frames a second. The trick is the one your maps app already plays on you: a pyramid of pre-cut tiles, called an octree, that loads detail only where you are looking. Here is the full machinery, with a runnable Python demo.

Visualise Massive point cloud in Python

By Dr. Florent Poux, PhD in 3D geospatial sciences | Author, 3D Data Science with Python (O’Reilly) | Published 16 February 2021 Visualise Massive point cloud in Python. Point clouds past the 10 million point mark are too dense for classical visualisation libraries such as Matplotlib, so this tutorial uses PPTK, which relies on an […]
