Prompt: Generate a detailed image of an indoor facility featuring a semi-Olympic swimming pool. The pool is housed within a textile enclosure, with a second translucent textile enclosure surrounding the first. A grand steel structure supports the ceiling, visible from a monumental grandstand. The scene is filled with activity: swimmers of various ages and skill levels are engaged in different swimming exercises and practices. The grandstand is populated with spectators, some cheering and others observing. The translucent textile enclosure allows soft, diffused light to illuminate the space, creating a vibrant and energetic atmosphere. The overall setting should convey a sense of dynamic movement and excitement.
