Here's roughly how that pipeline came together.</p> <p><strong>Keep the photo's geometry, change everything else.</strong> Renova is prompts on an image-edit model, plus a watermark. The prompts are written to keep the room's architecture and camera angle, so a "Scandinavian" redesign still has your window in the same wall, at the same size.</p> <p><strong>One pipeline, many tools.</strong> Style redesign, virtual staging (furnishing an empty room), new walls and floors, furniture rearrangement, style transfer from a reference photo, floor-plan-to-3D-rendering, and occasion decorating all share the same core step, just with different inputs and constraints. That made it possible to add a new "tool" without building a new pipeline from scratch each time.</p> <p><strong>One codebase, three platforms.</strong> Renova ships on iPhone, Android and the web from the same codebase, with the same account and the same design history following you between them.</p> <p>If you work on anything that edits or regenerates real photos rather than generating from scratch, the "keep structure, change material" problem is probably familiar — happy to compare notes in the comments.</p> <p><a href="https://renovaroom.com" rel="noopener noreferrer">https://renovaroom.com</a></p> design ai interior home
