Roof infinity pool illustration

Quick answer：

An infinity pool is a type of swimming pool that has one or more sides that appear to extend to the horizon. It is designed to give the illusion of water extending endlessly, often creating a stunning visual effect. Roof infinity pools are a variant where the pool is located on a building's roof, providing panoramic views and a unique experience. Illustrations of such pools typically show the pool's design, layout, and surrounding architecture.
