I want to create a small browser-based flight simulator prototype with a wireframe, sci‑fi aesthetic: terrain rendered as grid lines. It needs two viewpoints: (1) a third-person camera that follows the aircraft, and (2) a top-down 2.5D instrument panel/map view where the flight trajectory is clearly visible. Please implement it using React Three Fiber, with a custom GLSL grid shader for the terrain. I’d like smooth camera transitions (triggered via a key press or a button), and provide runnable prototype code.
