3d classroom interior

A clean 3D classroom interior designed for digital twin simulation, isometric view, cutaway style with open front wall. Bright and modern classroom with light beige walls, soft gray floor, and white ceiling. Include desks, chairs, whiteboard, and large windows with natural lighting. Desks in light wood with white frames, chairs in soft blue and mint colors. Add HVAC elements: ceiling air conditioner, simple ventilation ducts, wall-mounted fans, and circulators.

Visualize airflow with semi-transparent streamlines and arrows: cool air in blue tones, warm air in red and orange gradients. Add a soft heatmap gradient on the floor and air volume. Clean, modular layout for engineering simulation, realistic proportions, clean geometry. Low to medium poly, optimized, game-ready asset. Bright lighting, soft shadows, slight
