A photorealistic render is a computer-generated image of a space that looks like a real photograph. Traditionally it was produced from a 3D model with rendering engines such as V-Ray, Corona or Enscape; today AI can produce one directly from a photo of the room.
What makes a room render believable
- Coherent light: shadows fall the same way as the light from the windows, and lamps glow with a plausible warmth.
- Real materials: wood grain, fabric weave, reflections on stone or metal.
- Correct scale and perspective: furniture sized for the room, vertical lines that stay vertical.
- Small imperfections: a crease in a cushion, slight variation in a plaster wall. Perfectly clean scenes read as CGI.
Hero render and AI room render
In architecture and design, the hero render is the single best image of a project, the one used on the cover of a presentation. An AI room render is a redesign of an existing room generated from a photo. Both aim for photorealism; the AI version also has to keep the real room’s walls, windows and light, which is what ControlNet-style guidance and Tigmi’s Room Lock are for.
