Products that do what The Atlas – I Built a 3D Universe Simulation with Python and Three.js does
Hi HN! I’ve spent the summer of the past 2 years building The Atlas, a procedural universe simulator that generates 1 sextillion galaxies (10²¹) from a single mathematical seed. Think No Man’s Sky meets theoretical physics, but running entirely in your browser. Everything is purely deterministic, the universe is calculated from SHA-256 hashed seeds using the golden ratio as primordial constant. There’s no database, no pre-saved data, just pure math. Time itself is treated as a coordinate, so the universe exists as a 4D structure where any moment can be computed on demand. Shut it down for…

Hi HN! I’m Alex from Parabola (https://parabola.io). Parabola is a visual programming tool for creating functional data flows that everyone can use. It’s entirely drag-and-drop, handles data sizes much larger than a traditional spreadsheet, calculates everything live, and can run your flows on a schedule of your choosing. I used to work in strategy consulting, doing data analytics for SMBs and Fortune 500 companies. The amount of time wasted on menial tasks was astounding. Things like cleaning data, generating custom reports, creating human workflows to solve shortcomings in third…

We’re building TheorIA— an open, high quality dataset of theoretical physics results: equations, derivations, definitions, and explanations — all in structured, machine- and human-readable JSON. Why? Physics is rich with beautiful, formal results — but most of them are trapped in PDFs, LaTeX, or lecture notes. That makes it hard to: - train symbolic/physics-aware ML models, - build derivation-checking tools, - or even just teach physics interactively. THEORIA fills that gap. Each entry includes: A result name (e.g., Lorentz transformations) Clean equations (AsciiMath) Straightforward…

I built Seed3D, a next-generation 3D reconstruction and modeling tool that turns 2D inputs into solid, physics-ready 3D models — with millimeter precision, physically accurate PBR materials, and export formats ready for any major engine. Unlike traditional photogrammetry or AI mesh tools, Seed3D doesn’t fake geometry with normal maps — it reconstructs real surfaces, edges, and micro-details for simulation-grade accuracy and realism. What it does • Generates watertight polygonal meshes with crisp, true geometry • Outputs full PBR texture sets (albedo, roughness, metalness, normal, AO) •…

Hello HN: I love the randomness of the universe. I've been spending some time creating a Craps simulator to help experience this love without having to shell out like a real degenerate. For others similarly fascinated: I would love to hear any and all feedback you've got on this. It's meant to be unique in the sense that it's a community-oriented, infinite simulation.

Hello HN! We're the team behind Epistemeland (https://epistemeland.com/), a platform dedicated to making learning fun and accessible. We've just released a prototype of a single player game that uses basic geometry. It is a fist, but an important step in creating our MMO game to revolutionize education. The game mechanics are simple but intriguing and naturally incorporated in the game process. We built it with UE5 and want to continue development. We'd love for you to try it out and give us your feedback, which we'll use to guide our next improvement cycle. Our goal is to…

Hey everyone! I'm a huge F1 fan and got tired of juggling multiple tabs and apps during race weekends, so I built F1 COSMOS. What it does: - Live timing: Real-time data updates in milliseconds - sector times, telemetry, team radio, you name it. No more refreshing pages or waiting for delayed updates. - Replay feature: Missed qualifying or fell asleep during practice? You can replay the live timing from any past session. Pretty handy when you're in a bad timezone. - Proper data visualization: I went beyond just showing lap times. There's race analysis with telemetry data, championship…

I've noticed all 3D AI generators create monlithic blobs that are impossible to edit. So, alongwith a friend, I built this project where you can generate 3D objects with separate, editable parts. I'm looking for community feedback. The tool is free, but you'll have to BYOK. It uses models like Gemini, Claude or chatGPT to generate a Blender construction script. Basically the output is not merely geometry. It's the procedure that built it, plus the asset itself. This means you can actually go in and edit the "kit of parts" afterwards, instead of starting over.

Input a SMILES string (or pick one molecule from the examples) and it returns up to 100k molecules closest in 3-D shape or electrostatic similarity – from 10+ billion scale databases — typically in under 5-10 s. *Why it might interest HN* * Entire index lives on disk — no GPU at query-time, less than ~10 GB RAM total. * Built from scratch (no FAISS index / Milvus / Pinecone). * Index-build cost: one Nvidia T4 (~ 300USD) for one 5.5B database. * Open to anyone, predict ADMET, export results as CSV/SDF. Full write-up & benchmarks (DUD-E, LIT-PCBA, SVS) in the pre-print:…

Hey HN, I recently launched a podcast called The Multiverse Employee Handbook, where I mix light-hearted humor with some science fiction and a sprinkle of quantum physics. It’s set in a surreal corporate universe where office politics, interdimensional HR dilemmas, and wormhole deliveries are all part of the daily grind. Each narrative episode explores a different aspect of this multiverse, like quantum entanglement in the mailroom or cosmic deadlines. It’s definitely more on the fun and absurd side of things, but I try to weave in real science concepts (in the simplest way possible, of…

Hey HN, I wanted to make my life easier by using GPT products that could convert my words to raw MongoDb queries. - Uploading large datasets (50-70GB) in CSV format wasn't feasible for me. - MongoDB does have a "Generate query" feature, but it requires an Atlas subscription. My database is self-hosted. - Plus, I wanted the flexibility to use my own OpenAI API keys instead of paying extra for any GPT-based services available. So, we developed a product that tackles these challenges. It's still a work in progress, but I'd greatly appreciate any feedback.…

Hello HN! My name is Rémy and I recently published an astronomy dashboard where everything is open source: the code of the website, the framework it is based on and the library that computes astronomical data. For the last few years, I have been developing the Ruby library Astronoby (https://github.com/rhannequin/astronoby) with as much dedication and perseverance I could while I don't have any scientific academic background. My end goal was to use this library and build a website that not only provides as much data as possible, but let anyone access and understand how it…

Hi everyone, I started working on nanoeuler after the ban of anthropic's fable because my ambition and dream is to work in the AI field in anthropic. The two interesting reasons that led me to create nanoeuler were the first, interfacing with llm does not mean understanding how they are composed and two, working on llm with a very low-level layer to understand the correlation between parameters and data and growth of the model and how the GPU works and how some layers can be optimized. So I started working on it with a research aspect by making nanoeuler grow more and more but doing one step…

Hey HN, it's Vineeth from Plastic Labs (https://plasticlabs.ai) and we built this demo/game to showcase the latent capabilities of language models to simulate identities. We wrote more about what it is and how to use it on our blog (https://blog.plasticlabs.ai/blog/YouSim;-Explore-The-Multive...), but I'll try to quickly summarize. We took heavy inspiration from projects like WorldSim, WebSim, and Infinite Backrooms and prompted Claude Opus to act like a CLI interface that can simulate these identities while another instance will interact with the CLI. To…
