3D Heightmap Visualizer renders and lets you fly around heightmap-based terrain directly in the browser, no plugins or exports needed. It's a small, focused tool built to explore how far real-time 3D terrain rendering can be pushed with the modern React Three Fiber ecosystem.
Built with Next.js 16, @react-three/fiber and drei on top of Three.js, Tailwind v4, and Framer Motion for the surrounding UI.
