Meet Nano3D: The Magic Tool That Edits 3D Objects Without Any Training

What if you could reshape a 3D model like clay, without learning a single line of code? Scientists have unveiled Nano3D, a brand‑new, training‑free system that lets creators tweak virtual objects in seconds. Instead of juggling complex masks or rebuilding the whole scene, Nano3D works like a smart brush: you point at the part you want to change, and the tool instantly blends the edit while keeping the rest of the model perfectly intact. Imagine a video‑game designer adjusting a character’s armor on the fly, or an animator fixing a robot’s arm without re‑rendering the whole world – all with the same ease as doodling on paper.
