Three.js 照片转 3D 体素工作室，带波浪动画

Build a browser tool in Three.js that turns an uploaded photo into an interactive field of more than ten thousand 3D pixels. Sample the image on a grid and render each cell as an instanced sphere, cube or cylinder coloured from the photo, so the whole field costs a single draw call and stays near 60 FPS. Add a dark background and a compact control panel with an image upload, a shape selector, a material theme selector (original colours, metallic, neon), sliders for grid resolution, wave amplitude, wave speed and depth extrusion, an auto-rotate toggle, and buttons to export an animated GIF and a high-resolution PNG. Animate the voxels with a travelling 3D wave displacement and allow orbiting and zooming close to see individual shapes. Done means any portrait can be dropped in and explored live.
