Project details
This initiative brings a physical exhibit to life online, transforming it into an interactive 3D experience centered on a coastal/waterfront environment. Through a navigable underwater terrain dotted with points of interest, visitors are guided through storytelling that highlights climate change, rising sea levels, and the marine ecosystems affected by them - supported by dynamic, time-based data overlays such as sea-level trends, ecological indicators, and environmental monitoring data.
The platform serves two audiences: the general public, who engage with an immersive, educational visualization; and professional content teams, who use an authenticated CMS interface to curate narratives, manage content, and reuse educational modules across future initiatives.
Technically, the platform combines a Next.js/React frontend, Three.js/React Three Fiber for 3D rendering, a Strapi (Node.js) headless CMS backend with Redis caching, and Blender-produced 3D assets - integrated with an external dataspace via a participant agent. Delivery is structured across 5 phases: Onboarding, Core Components & Demo, Scenarios for Professionals, Public-Facing Adaptation, and Operational Improvement.
