High-rise building with infinity pool effect drawing

Quick answer：

An infinity pool is a pool designed to give the illusion of water extending to the horizon, often seen in luxury high-rise buildings. These pools are typically located on the building's roof or at a very high level, with the water's edge blending seamlessly with the surrounding landscape or skyline. The 'effect drawing' refers to an illustration or visual representation of this concept, often used for architectural or marketing purposes.
