@oragnes: Wow, just dug up this amazing tool map3d on GitHub! Based on OpenStreetMap, you select an area on the web page, and it automatically fetches real building and road data, rendering a 3D city model with heights in one click! The craziest part is it can directly export GLB files for use in Blender or game engines…

Summary

Introduces two open-source tools on GitHub: map3d, which automatically generates 3D city models from OpenStreetMap and exports GLB files; and Voice-Pro, a local tool integrating video download, voice separation, subtitle recognition, translation, voice cloning dubbing, and video synthesis.

Holy cow, just discovered this incredible tool map3d on GitHub! Based on OpenStreetMap, you select an area on a web page, and it automatically pulls real building and road data, rendering it into a 3D city model with heights in one click! The killer feature is it can directly export GLB files, ready to use as assets in Blender or game engines! Pure front-end real-time rendering — just a few lines of React code and you have a smart city prototype. Digital twin engineers and designers, go grab it now. Save it first, you'll need it sooner or later!

Holy moly, I just stumbled upon an incredible tool on GitHub — map3d. Based on OpenStreetMap, you just draw a selection box on a web page, and it automatically pulls real building and road data, then renders it into a 3D city model with height — all in one click.

The best part? It can directly export GLB files that you can drop into Blender or a game engine as assets!

Pure frontend real-time rendering — you can get a smart city prototype up and running with just a few lines of React code. Digital twin engineers and designers, go grab it now. Star it — you’ll need it sooner or later!

Bitcoin Orange Trader (@oragnes): Just found an extremely hardcore open-source project: Voice-Pro.

Voice-Pro takes the tedious audio/video workflow of:

Video downloading
Vocal separation
Subtitle recognition
Text translation
Voice-cloning dubbing
Video compositing

and packages it all into a no-code local tool with a Gradio interface.

💡 Key highlights & sweet spots:

It integrates top-tier open-source ecosystems (WhisperX for recognition, Demucs for vocal separation, Alibaba

Let me mention a few designs I found impressively unconventional: It comes with a "semi-finished" attribute out of the box — the generated model isn't a rigid photo texture, but includes clear hierarchy and collision body components...
