A 6-block sculpture sits fixed on a table. First frame: Your camera is tilted at 31° elevation, viewing from 140° azimuth. Final frame: Your camera remains at 31° elevation, but rotates horizontally to 320° azimuth. This is a 180-degree rotation. The camera rotates horizontally around the sculpture; try to maintain the tilted viewing angle throughout. Only modify what the task requires; keep the background and any other element unchanged. Output 4 images showing the camera's horizontal rotation at uniform progress intervals.
