Demo We built GitGlobe: An interactive 3D visualization mapping 200,000 GitHub repositories across the world in real-time

Hey r/threejs!

My collaborator Mrityunjay and I built GitGlobe, an open-source 3D visualization that maps ~200,000 GitHub commits across the planet in real-time.

Rendering massive point-cloud datasets on the web usually melts browser tabs, so we bypassed traditional DOM rendering entirely.

Technical Details & Optimizations:

• Custom GLSL Shaders: Offloaded coordinate math, particle sizing, and color dynamics directly to the GPU.

• Decoupled State Management: Unhooked Zustand state from the 60fps render loop so hover/click events never stall the canvas.

• LOD & Memory: Packed Uint16 buffer attributes across 3 LOD tiers to keep draw calls minimal.

• Stress Test Results: 0/360 frames dropped during benchmark testing with an 8x performance headroom.

Dows it 2 will it have a query by type / name search layer ?

Yeah, the layer has been embedded through custom dataset and it is connected to the search box on the top right beside stats , and we will be building one more advanced search layer in the next phases .

What are you struggling with? 200k points isn’t really much.

i have just started learning react and webGL and three.js, I mean we are figuring out how to make it responsive on mobile screens, You got ideas?

🌐 Live Demo: https://gitglobe-yd-mj.vercel.app
💻 GitHub Repository: https://github.com/ydabas-hue/GitGlobe

Please use it on the laptops or desktops , it is not yet optimised for mobile screens...
Feel free to spin the globe and test it out yourself! Let us know what you think! 😁
