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.

Multi-View Engine for 3D Generative AI Models (Python Tutorial)
Generate perfect multi-view 3D training data without cameras. Mathematical algorithms create optimal viewpoints for Gaussian Splatting in minutes, not days. Stop Shooting Photos for 3D AI Training Data (Use This Instead) I have a fun story to share. I watched a team spend €15,000 on camera equipment and two weeks of labor to capture training

3D Scene Graphs for Spatial AI with NetworkX and OpenUSD
Learn to build intelligent 3D scene graphs from point clouds using Python, NetworkX, and OpenUSD. Complete tutorial access with LLM integration for spatial AI. The hardest part of spatial AI isn’t capturing the data. It’s making that data actually intelligent. You’ve got millions of perfectly labeled 3D points, but when you try to build something
