Generate a hyper-realistic render of a modern and elegant cultural center interior. The scene should depict a spacious and bright cultural hall with high ceilings, walls in slotted concrete and large windows, creating a sense of openness. Include a large screen or projector displaying high-quality content, with a diverse group of people attentively watching. Integrate indoor trees or plants to add a natural touch. The architectural design should feature modern, high-detail elements, including stylish black metal columns, soloted concrete panels at te bottom, and metallic accents. Highlight innovative and sustainable percolating floors with an attractive, functional finish. Ensure the ambient lighting accentuates the design features and creates a welcoming, vibrant atmosphere.
