Sharp Monocular View Synthesis in Less Than a Second: How Apple’s SHARP Turns a Single Image into Real-Time 3D “ Core question: Can one ordinary photo become a photorealistic 3D scene you can rotate in real time, without lengthy per-scene optimization? Short answer: Yes—SHARP produces 1.2 million 3D Gaussians in <1 s on one GPU and renders at 100 FPS with state-of-the-art fidelity. What problem does SHARP solve and why is it different? Summary: SHARP targets instant “lifting” of a single photograph into a metric, real-time-renderable 3D representation, eliminating minutes-long optimization required by NeRF-style approaches while improving visual quality over …
