Digital TwinWhat Is a Digital Twin? A Complete 2026 Guide to How It Works, Its History, Use Cases, and Differences from the Metaverse and Simulation
A practical guide to digital twins covering their history, architecture and use cases in manufacturing, cities, construction, healthcare and aviation. It also explains how they differ from simulations, the metaverse and CPS, and why effective twins do not always require 3D graphics.
AI DevelopmentSEO in the Age of AI Search: Build a Knowledge System, Not Just More Articles
Publishing more articles does not automatically build authority. This guide explains how topical coverage, semantic SEO, original value, content cannibalisation management, internal links and site architecture work together to create a coherent knowledge system for AI-driven search.
AI DevelopmentAI Voice Production: 5 Best Practices
AI voice content uses two AI stages: script generation and text-to-speech. This guide explains how to test predefined voices, turn subjective feedback into requirements, manage versions, prioritize trade-offs, run group listening sessions and use post-processing to stabilize quality.
AI DevelopmentTurning Google Colab into an API Server to Run Speech-to-Speech Voice AI
This PoC turns Google Colab into a temporary WebSocket server for speech-to-speech AI. It combines faster-whisper large-v3, Gemini 2.5 Flash-Lite, VOICEVOX and Silero VAD, then improves latency through sentence buffering, streaming responses and parallel TTS generation.
3DWhat Is 3D Tiles? A Complete Guide to Its Core Concepts, Latest Trends, and Use Cases
3D Tiles is an open standard for streaming massive 3D geospatial data. This guide explains HLOD, bounding volumes, tileset.json, differences between versions 1.0 and 1.1, use cases including PLATEAU and Google Photorealistic 3D Tiles, and independent LOD control in CesiumJS.
AI DevelopmentWhat We Learned Building Voice AI with Gemini: The Major Difference Between a PoC and a Commercial Service
A Gemini Live API PoC can deliver real-time voice conversations quickly, but production introduces concurrency, quotas, observability, model lifecycle and device-specific audio issues. This article explains why the architecture moved from direct browser access to LiveKit and Vertex AI.
Business & CultureWhat I Did to Pass the PMP Exam
Nihei, a project manager at Vitalify Asia, explains how he prepared for and passed the PMP exam. From the 35-hour course and a Japanese exam guide to repeated Study Hall practice and taking the test in Bangkok, this article covers the full journey and lessons learned.
AI DevelopmentA Concept for Developing AI Through Artificial Languages
Can AI learn logic more efficiently through an artificial language than through natural language? This article compares Esperanto, Lojban, and Ithkuil, then presents a custom GPT-2 model trained from scratch on Lojban-based data that achieved 100% accuracy on prepared three-valued logic tests.
AI Development7 AI Image-to-3D Generators I Tested in 2026: Which One Is Actually Worth Using?
Using the same portrait and default settings, we tested Prism 3.1, Meshy 6, Tripo P1, Hunyuan3D, Forge, Trellis 2 and Rodin 2.5. See how they compare in facial similarity, texture, hair, clothing and mesh quality, plus which tools work best for realism, game assets and further editing.
Product DevelopmentGLB Texture Editor: Edit 3D Model Textures and Materials in Real Time in Your Browser
GLB Texture Editor is a browser-based tool for editing 3D model textures and materials in real time. Upload a GLB file, adjust base color, roughness, metalness, transparency, UV mapping, position, rotation, scale, and projection settings, then preview and export the updated model.
Digital TwinHigh-Performance Web BIM Viewer for Large IFC Models
This PoC converts large IFC models into optimized GLB files by BIM category for faster browser rendering. It demonstrates flexible layer controls, element data panels, smooth 3D navigation, and reduced z-fighting, while outlining a future automated IFC-to-GLB workflow.
