Mocku
Real 3D mockups you can fully customize
What it does
Most mockup generators give you one fixed camera angle, so everything made with them looks the same. Mocku uses real 3D devices rendered with Three.js in your browser. Turn the device to any angle, set the lighting and the shadow, add props and backdrops, then export. Handcrafted preset scenes get you a finished look in seconds, and what you see in the editor is exactly what exports. Free includes the full editor and every device. Pro adds 3x exports, the full scene library, and video.

- M3MockRocket – 3D app mockups and animations in the browser2022 · mockrocket.io · ▲75
Hey HN, I've spent a lot of time over the years building mockups and demo videos for my apps with tools like Photoshop and After Effects, always frustrated by how tedious it was. For the past year and a half, I've been working on building a better way. MockRocket makes it easy to show off your app, right from your web browser–no experience required. Choose a template, drag and drop a screenshot or video and display it on a realistic 3D device model. You can even animate it to create a video. You can customize as much or as little as you want, and export in up to 4K resolution. All rendering…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
