The application uses Next.js with React Three Fiber for 3D rendering. ## File Structure ### `app/` - `page.tsx`: Main entry point. Renders the full-screen Canvas. - `layout.tsx`: Global layout (fonts, metadata). ### `components/scene/` - `warp-scene.tsx`: The main 3D scene container. Handles the camera, animation loop, and intensity logic. - `tunnel-mesh.tsx`: The actual 3D mesh (Box) with the custom shader material. - `effects.tsx`: Post-processing effects configuration (Bloom, Noise, Chromatic Aberration). - `shaders.ts`: Custom GLSL shader definitions for the tunnel material. ## Feature Manual ### Animation Sequence The animation is approximately 20 seconds long and loops or holds at the end. - **0s - 5s (Warmup)**: Slow movement, darker colors, low FOV. - **5s - 15s (Acceleration)**: Speed increases exponentially. Colors shift from cool blues to hot reds/oranges. FOV widens to simulate speed. - **15s - 20s (Plaid Mode)**: Maximum speed. High chromatic aberration. Intense bloom. Pattern becomes chaotic. ### Custom Shader The tunnel uses a custom fragment shader to generate: - Infinite depth illusion via UV scrolling. - Grid/Plaid patterns. - Radial light streaks.
