Make “Red and White Isometric Diorama Poster” yours

Generate a 3D miniature diorama render centered on a specific themed building or structure. Use an isometric view, placing the building right in the center of the frame with generous negative space all around; the background uses a seamless, pure cream-white / light warm-gray backdrop, creating a clean, studio-grade display space. The visual core lies in a strict red-and-white two-color scheme and deconstructed mapping: extract all of the building's load-bearing skeleton, edge frames, and structural lines (columns, beams, door and window frames, railings, contour trims, etc.) and convert them into a highly saturated, visually striking Chinese red (vermilion); at the same time, convert all of the building's enclosed surfaces, walls, roofs, bases, and large solid areas into a pure, flawless white. Reject any superfluous stray color; convey the building's complex structure solely through the interwoven contrast of the red framework and white volumes. For the material, present the matte texture of a blind-box designer toy or a high-end textureless 3D model, with an absolutely smooth surface, discarding any real wood grain, stone texture, or aged imperfections. Combine this with soft global diffuse illumination (Global illumination), casting clean, soft-edged shadows and ambient occlusion onto the white walls and base plate, so the entire miniature scene exudes a minimalist, modern, and highly refined structural-aesthetic atmosphere.
