The tool, published by codepawl under an MIT license, allows users to create interactive 3D scenes by describing them in plain language. The author tested the skill on an old iMac using a fictional restaurant lunch rush as the subject. The test proceeded in three stages: a basic version using simple shapes, a Blender-enhanced version with detailed models, and a realistic version using the MPFB human body tool.\n\nThe skill operates by following a defined procedure: planning, building models, assembling the app, and self-inspecting. A key feature is the 'self-inspection' cycle, where the AI takes screenshots of its own output, measures performance, and corrects errors such as overlapping surfaces or unrealistic movements. In the simple version, the AI identified and fixed a logic bottleneck where trays filled the counter, stopping the simulation. In the Blender version, it created 13 types of equipment and 8 types of animated people. The final stage added realistic human bodies and specific tool-handling movements, with the AI correcting visual glitches like clothing clipping.\n\nThe test demonstrated that viz3d can produce functional 3D simulations with calculated metrics, camera controls, and video export capabilities. The author noted that the process is deterministic, meaning the same inputs yield the same results. The skill requires Node.js, Playwright, and ffmpeg, with Blender optional for higher fidelity. The entire process, including model creation and video generation, took approximately an hour for the Blender version.","keyPoints":["viz3d is an MIT-licensed skill for Claude Code that builds 3D apps with self-inspection.","The AI corrected visual and logic errors by analyzing its own screenshots during the build.","The test produced a 30-second 1080p video of a restaurant simulation on an old iMac."],"whyItMatters":"This demonstrates a practical application of AI agents for complex 3D visualization and simulation, allowing non-experts to create interactive models and videos without manual coding or 3D design skills.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["codepawl"],"models":["viz3d"],"people":[]},"firstPublishedAt":"2026-10-30T09:41:00Z","updatedAt":"2026-10-30T09:41:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"A Complete Guide to the AI Skill 'viz3d': Testing How Much It Can Do with Claude Code and an Old iMac|ポポコム武田|飲食を20年見てきたマーケター","url":"https://note.com/kicdcry/n/n9150650ece6a?hl=en","publishedAt":"2026-10-30T09:41:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Viz3d skill lets Claude Code build and self-correct 3D simulations\", 30 October 2026, https://digestai.news/story/viz3d-skill-lets-claude-code-build-and-self-correct-3d-simulations","publisher":"Digest AI","title":"Viz3d skill lets Claude Code build and self-correct 3D simulations","datePublished":"2026-10-30T09:41:00Z","url":"https://digestai.news/story/viz3d-skill-lets-claude-code-build-and-self-correct-3d-simulations"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
