等距视角科学概念立体模型网格

A clean 2x2 conceptual entity model infographic on a soft light background, showing four separate floating isometric diorama tiles that personify branches of {argument name="theme" default="science"} in a polished 3D illustration style with pastel gradients, glossy materials, soft ambient lighting, subtle shadows, rounded futuristic forms, and high detail. Top left: BIOLOGY, a lush bio-lab island with a large central DNA double helix tower, curved glass greenhouse architecture, spiral stairways, layered organic pathways, greenery, plant beds, and fluid biomorphic structures; the word "BIOLOGY" is integrated on the front edge of the platform. Surrounding this tile are 4 small biology-related icons: a microscope, a DNA symbol, a sprouting plant, and a circular cell or petri-dish symbol. Top right: PHYSICS, a high-tech energy laboratory tile in cool blue tones with a central glowing platform, circular accelerator rings, copper-like electromagnetic coils, stairs leading up to the core, a monitor screen with waveform graphics, and a futuristic industrial base labeled "PHYSICS"; add 4 surrounding physics-themed icons: an atom, a horseshoe magnet, a lightning bolt, and a line graph waveform. Bottom left: CHEMISTRY, a modular molecular research structure in purple and silver, built from spheres-and-rods lattice frameworks, lab columns, beakers, flasks, and a glowing crystalline core; the platform prominently reads "CHEMISTRY" on two visible sides. Surrounding this tile are 4 chemistry-related icons: two molecular diagrams, a pair of lab test tubes or flasks, and a small burner. Bottom right: ASTRONOMY, a rocky lunar observatory island with cratered terrain, a dome observatory, a telescope, stairs carved into the rock, and a circular cosmic starfield backdrop behind it; the front edge reads "ASTRONOMY". Surrounding this tile are 4 astronomy-themed icons: a ringed planet, spark-like stars, a small rocket, and a crescent moon. Keep all 4 tiles evenly spaced in a quadrant layout, each with its own muted geometric backdrop shape, cohesive pastel palette tuned per discipline, and a premium gpt-image-2 style that makes each concept feel like a collectible miniature world. No people, no extra text beyond the four discipline labels.
