    I built a synthesizer based on 3D physicsfree tier, from $99/mo▲512

    I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with…

    It's been closed source for a long time while I worked on it on and off as a hobby research project, but yesterday the repo was made public for the first time under the MPL 2.0 license. A feature reel showing its capabilities can be found here: https://ktstephano.github.io/rendering/stratusgfx/feature_re... A technical breakdown of a single frame can be found here: https://ktstephano.github.io/rendering/stratusgfx/frame_anal... It's still in a very beta state (bugs and instability expected), but I felt like it was a good time to make it…

    Render 3D models (OBJ, glTF, GLB, STL, .vox) as ASCII art — in the browser, in React or Vue, or straight in your terminal. A three.js-style API with no WebGL and no canvas: just text in a single <pre>.

    I'm currently developing Chili3D, an open-source, browser-based 3D CAD application. By compiling OpenCascade to WebAssembly and integrating Three.js, Chili3D delivers near-native performance for powerful online modeling, editing, and rendering—all without local installation. Access it here: https:&#x2F;&#x2F;github.com&#x2F;xiangechen&#x2F;chili3d Features: Modeling Tools: Create basic shapes (boxes, cylinders, cones, etc.), 2D sketches (lines, arcs, circles, etc.), and perform advanced operations (boolean operations, extrusion, revolution, etc.). Snapping and Tracking: Precisely snap to…

    I ported Microsoft's TRELLIS.2 (4B parameter image-to-3D model) to run on Apple Silicon via PyTorch MPS. The original requires CUDA with flash_attn, nvdiffrast, and custom sparse convolution kernels: none of which work on Mac. I replaced the CUDA-specific ops with pure-PyTorch alternatives: a gather-scatter sparse 3D convolution, SDPA attention for sparse transformers, and a Python-based mesh extraction replacing CUDA hashmap operations. Total changes are a few hundred lines across 9 files. Generates ~400K vertex meshes from single photos in about 3.5 minutes on M4 Pro (24GB). Not as fast as…

    Hey HN! I'm Zach from Adam (https:&#x2F;&#x2F;adam.new&#x2F;). We’re building an AI co-pilot for mechanical CAD software. As part of our broader research, we built a browser-based Text-to-CAD app (https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44182206) and are now open sourcing it. This is a React SPA with a Supabase backend. What it does: * Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references * Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension…

    Hey HN, I'm a beginner at CAD so I built an app that does it for me ;) Describe a part and ChatToSTL writes the OpenSCAD code, shows a live render with size sliders, then exports the STL&#x2F;3MF file. Because the output is parametric, it's easy to modify (unlike mesh models like Shap-E or DreamFusion). Try it (needs your own OpenAI key): https:&#x2F;&#x2F;huggingface.co&#x2F;spaces&#x2F;flowfulai&#x2F;ChatToSTL How it works: Text prompt → o4-mini generates OpenSCAD code → live render + sliders → refine in chat → export. Examples & Code: * Walkthrough + real prints (bowl, hook, box, door…

    I’m a Technical Artist. I built anyCreature, an open-source, mesh-based generative harness designed to programmatically quantify and enforce 3D aesthetics through three automated pipeline checks: 1. QC Thresholds: Automated pass&#x2F;fail checks for standard game-engine specs (poly count, vertex budget, rigging, and animation tracks). 2. Quantified Aesthetics: Spatial vertex analysis to objectively measure mass distribution and form tension, ensuring biologically logical anatomy. 3. Silhouette & Readability: Automated high-contrast B&W renders and 24px thumbnail tests to guarantee visual…

    Hello internet folks! I'm happy to share the first TestFlight release of Glyph3D, a 3D text visualizer for macOS and iOS. It's free, supports pretty much any utf8 data, and is a pretty interesting way to navigate your repositories or data directories without the limitations of standard text windows! Download and bookmark for macOS and iOS: https:&#x2F;&#x2F;github.com&#x2F;tikimcfee&#x2F;LookAtThat&#x2F; - You should be able to download public repos from GitHub and render them. - Play with opening and closing windows. I've disabled many of the in-flight features to keep user confusion down,…

    This is part of my journey on pybind11. I wrote a tiny FM Synthesis library in C++ and a Python wrapper for that using pybind11. There is a command-line piano app in the examples directory if you want to play with it. Here is the link: https:&#x2F;&#x2F;github.com&#x2F;charstorm&#x2F;koelsynth&#x2F;tree&#x2F;main&#x2F;examples&#x2F;si... My next target is to attach this to some kind of physics simulation - like a bunch of balls moving around in a box with some internal walls. When the ball hits certain trigger points, it produces the sound.
