OpenAI Day

Hi Product Hunt! I'm Howie, the maker behind 3DOME Taipei (also founder of Protico) I got tickets to my first baseball game at Taipei Dome and wanted to answer one simple question: what would the view from my seat look like? That question became 3DOME: an interactive 3D simulation you can explore before you arrive. Enter your section, row and seat, or simply photograph your ticket and review the text recognized on your device. Then move into a simulated seat view and look around. You can switch between baseball and concert configurations, explore stage layouts, and even step onto the virtual field for a batting challenge. I built it purely with GPT-6 Astra in Codex, guided by human design decisions and repeated testing. I even brought my laptop to a game and kept iterating with Astra from my actual seat, checking the simulated view against the real one. Turning the first model into a useful experience also meant listening to fans, checking views against available references, and refining the interaction. The challenge was making a complex 3D space easy for someone holding a ticket to use. The response has been the biggest surprise. Three fans posted their own walkthroughs on Threads, and together those three posts have displayed more than 290,000 views, 16,000 likes and 10,000 shares as of September 18. None of them were ours. People quoted them to share the simulated view for their own section. 3DOME has also been covered and featured by several media in Taiwan, and referenced by Hong Kong's unwire.hk, with less than 7 days since its beta launch. That attention also turned into a steady stream of feedback. Fans leave requests and corrections in the in-app lobby while they explore, and with Astra in Codex I could turn them into shipped changes fast. A wish for a BIGBANG show became a pre-show concept layout, and every update since has gone through the same loop: fan feedback in, Astra iteration out. 3DOME is an independent, unofficial simulation. Seats, sightlines and stage layouts are illustrative; actual event conditions can differ, and future-show concepts are labeled. Try the English demo: https://3dome.taipei/en?mode=con... I'd love to hear: what would you need to see in a seat preview to feel better prepared for an event? Fan demo: https://www.threads.com/@apple.d... Fan follow-up: https://www.threads.com/@its.gdm...
