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.
Open-Vocabulary 3D Semantics in Python: SAM, CLIP, and DINOv2 (No Training)
Turn a careless phone video into a labeled, scaled, measurable 3D room with pretrained SAM, CLIP, and DINOv2, and not one training run. A nine-step open-vocabulary 3D semantics pipeline in Python.

3D Pipeline Architecture: A Founder’s Blueprint
It was a Tuesday when I got the call. A €40,000 project was completely stalled, burning cash every hour. The reason? The one person who knew the specific sequence of clicks to get data from their laser scanner software into AutoCAD was on vacation. The entire, expensive, high-tech 3D data pipeline was held hostage by
