21st #Busan Fireworks Festival is coming on Nov. 7!
Fireworks Festival Hotspot Map analyzes real terrain, building heights, and visibility to help you find the best free viewing locations in Busan. Launch coming early next week. No ticket? No problem. Just enjoy the show!
NextSIM, our AI-based traffic simulation, keeps growing! New: passenger boarding for buses & subways, plus upgraded rendering. All real simulation results.
Built with KAIST & KOTI,@Gaia3D. Presenting tomorrow at #ITSWorldCongress #NextSIM #DigitalTwin #AI
Did you know that low-pressure swirls can be visualized on Iwfgara (iwfgara.com)? Iwfgara is a free, web-based 3D weather data visualization platform operated by @Gaia3D
Iwfgara now comes in 2D, too! Explore the Earth’s breath on a flat map, plus faster, lighter wind vector rendering. Free web platform for NOAA & ECMWF weather data, from cm-scale terrain to outer space!

Excited to share the latest progress of #NextSIM, a next-generation AI-powered traffic simulator built on digital twin technology.
Led by Prof. Hwasoo Yeo (@KAIST) in collaboration with @Gaia3D, KOTI, and partners.

최근에 회사에서 런칭한 프로젝트 사이트에 대한 홍보 영상을 모션 그래픽으로 만들어봤어요. Opus 5.5와 @Promptwhat 님의 프롬프트를 참고하여 20분만에 초안을 완성하였습니다.

Honored to keynote GIS-IDEAS 2026 at Hanoi University of Mining and Geology, Vietnam on what should tokenize space for a Geospatial Foundation Model: pixel, voxel, or object graph? The conversations with fellow researchers were the real highlight. Thanks to the organizers.
We recreated the 2011 Tohoku #tsunami using WebGPU-accelerated SWE & open geospatial data. Validation showed promising accuracy, including tsunami arrival time at Fukushima. A browser-based platform for flood, tsunami, #landslide, and water-flow simulation will be released soon.
My team at @Gaia3D has simulated part of the #Nepal–Tibet flash #flood using #magoFluid. Initially I assumed water hit the border checkpoint from behind. This shows a massive flow passing alongside swept over it. Thoughts are with the victims.
Thrilled to share that @Gaia3D has been named one of the GeoAwesome Global Top 100 Geospatial Companies 2026. A huge milestone for our team in advancing open source GIS and digital twin technologies on a global scale. Thank you.

My colleague released a powerful, web-based glTF Inspector! Drag & drop .glb, .gltf. Inspect hierarchy, materials, & raw JSON. Switch debug views (PBR, Wireframe, etc.) 100% Local (No server uploads)
Demo: znkim.github.io/gltf-inspect… GitHub: github.com/znkim/gltf-inspec…

Meet glTF-Inspect. Most web-based glTF viewers render. This one analyzes. It was built and open-sourced by the colleagues who developed our 3D Tiles engine, mago3D-Tiler. Give it a look. znkim.github.io/gltf-inspect… #gltf #threejs

안녕들 하십니까.. 저는 회사를 그만두고 쉬다가 집에서 이런거 만들고 있습니다. github.com/Julian-adv/OpenMM… 브라우저에서 돌아가는 오픈소스 일인 개발(+AI) mmo입니다.
가이아쓰리디가 올해 과기정통부의 [오픈소스 개발자대회]를 후원하고 공간정보 분야 과제를 내걸었습니다. 저희가 낸 과제는 "COPC(Cloud Optimized Point Cloud)를 CesiumJS에서 바로 가시화하는 오픈소스 개발"입니다. 상금은 300만원입니다. 자세한 사항은 osscontest.kr/ 참고하십시오.
In celebration of the 2026 World Cup, our team has filled the Seoul World Cup Stadium, the venue for the 2002 World Cup opening match, with a celebratory drink. This simulation was performed directly in a web browser using #magoFluid, developed with WebAssembly.
