Could you build this?
No This is a peer-reviewed computer vision research project (CVPR) requiring novel diffusion model architectures and deep generative neural rendering techniques.
What it would actually take: The system requires training or fine-tuning diffusion-based image-to-image models conditioned on 3D spatial light tokens and depth maps, likely using PyTorch on large GPU clusters. The core technical hurdle is disentangling intrinsic image properties (albedo, surface normals, and ambient illumination) to realistically re-render specular highlights and shadows. This requires cutting-edge academic computer vision research and massive synthetic lighting datasets.
