Prompt de imagem
Transform the attached interior photograph into one finished 2.5D isometric architectural cutaway of that same room. The photograph is the source of the room, furniture and colors. This is a photo transformation, not a request to design a new room or reproduce an existing diagram.
PRESERVE THE PHOTOGRAPH
Identify the visible room boundaries, openings, windows, built in storage, furniture, lighting fixtures, artwork, plants and circulation space before drawing. Keep the relative positions, scale, recognizable silhouettes and relationships of those elements. Preserve the original room's dominant colors and material identities, translated into simple matte color areas. If the input changes, follow the new photograph. Do not impose a Bauhaus interior, a red rug, a black sofa, blue chairs or any other furniture that is absent from the supplied photograph. A window, shelf or passage must stay on its original side of the room. Infer only the minimum hidden geometry needed to complete the cutaway, consistent with visible evidence.
ISOMETRIC VIEW AND CUTAWAY
Reconstruct the photographed room as a coherent three dimensional space and show it from an elevated corner in a standard isometric view. Use parallel verticals and two ground plane axes at approximately 30 degrees to the horizontal, with no vanishing point or wide angle distortion. Remove the ceiling and the two foreground walls to expose the interior. Retain the relevant rear walls, wall thicknesses, openings and a thin continuous floor slab. Choose the viewing corner that reveals the furniture arrangement and circulation most clearly. Rotate the view as a whole rather than moving individual objects. Keep furniture seated naturally on the floor at the correct scale. Do not stack, enlarge, shrink or rearrange pieces to fit the composition.
DRAWING TREATMENT
Combine precise architectural line drawing with clean vector illustration. Use crisp black outlines, fine internal furniture and joinery lines, and heavier dark edges on cut walls and the floor perimeter. Simplify photographic grain, reflections, upholstery and wood texture into restrained matte flat colors. Keep enough detail to recognize the original sofa, chairs, tables, cabinetry, artwork and plants. Show volume through a few discrete tonal planes and subtle contact shadows, not glossy rendering, dramatic lighting or heavily shaded photoreal materials. Preserve the photograph's core palette instead of recoloring the room to match another example.
CANVAS AND ANNOTATION
Place the complete cutaway on a pure white background. Center the room with generous uninterrupted margins so every corner, wall edge and optional callout remains inside the canvas. Use thin unobtrusive leader lines and short English labels for clearly identifiable features such as the sofa, armchair, coffee table or storage. Keep labels outside the room and avoid crossed lines. Do not invent dimensions, room area or millimeter values from a single photograph. Add numeric measurements only if the user supplies them, copying those values exactly. The result is an illustrative spatial analysis, not a measured construction document.
OPTIONAL CHARACTER PASS
The architectural conversion is the main result. Do not add cartoon people or animals by default. If the user separately supplies a character reference and requests an action, add that character in a second edit of the completed cutaway. Match the requested drawing style and room scale, ground the character naturally in the scene and preserve the room, furniture and composition from the first pass.
OUTPUT
Return only the completed architectural cutaway image. Do not include the original photograph, a before and after collage, a presentation slide, app controls, captions across the artwork, watermarks or a surrounding decorative frame.
NEGATIVE PROMPT
A newly designed room, generic Bauhaus furniture, copied layout from an example diagram, changed floor plan, moved windows, missing signature furniture, invented fixtures, duplicated objects, exaggerated furniture size, floating objects, fisheye perspective, converging verticals, photoreal rendering, glossy materials, excessive texture, fabricated measurements, default cartoon characters, cropped corners, clipped labels, platform UI, watermark or signature.
