A developer used OpenAI's new Astra model to recreate Barcelona's Camp Nou as an interactive 3D web experience. Key highlights:
- 86,964 individually selectable seats: click any seat to preview the exact view from that position
- Three lighting modes: daylight, golden hour, and floodlit night
- Performance optimization: overview seat geometry reduced from 2,087,136 to 695,712 triangles (67%) without cutting seats
- Implementation details: procedural geometry and custom BufferGeometry for the stadium; InstancedMesh, spatial batching, and distance-based LOD to render 87K seats efficiently
A live web demo is available.
