lecture hall 3d model

Modern empty university lecture hall in amphitheater style with semi-circular tiered seating arrangement. Approximately 10-11 rising tiers of curved wooden desks with attached black chairs, forming a wide semi-circle facing the front. The lowest tier is at the same floor level as the lecturer's area, with each subsequent tier stepped up by about 0.5 meters higher than the previous one, creating a steep but comfortable amphitheater rise toward the back wall. Wide central aisle and side staircases for access between tiers. Carpeted floor in beige/gray tone. Front area has a central wooden lecturer's desk with computer monitor, keyboard, mouse, and office chair. On the front wall: large modern interactive digital whiteboard (smart board) on the left side and a large pull-down projector screen above the center. Wooden wall panels in warm brown tone, neutral beige side and back walls, recessed ceiling lights with fluorescent panels. Spacious layout with plenty of room between rows and around the lecturer's area. R
