It starts with understanding the room, not the products
The thing that separates a real generator from a sticker app is spatial understanding. When you upload a photo, the model estimates the geometry of the space — where the walls meet the floor, how deep the desk surface runs, where the natural light falls and from which direction. That spatial map is what lets the generated desk, monitor and chair sit at believable scale and cast believable shadows.
This is why a generic 3D room planner so often disappoints: it gives you a perfect virtual box that looks nothing like your slightly-too-small bedroom corner with the radiator under the window. Generating into your actual photo keeps the result honest. The setup you see is the setup you can actually build, in the room you actually have.
