Nighttime infinity pool illustration

Quick answer：

An infinity pool is a type of swimming pool with a design that gives the illusion of extending to the horizon. This is achieved by having the pool's edge line up with the land or the horizon, and sometimes using a vanishing edge technique. Nighttime illustrations of infinity pools often depict the pool illuminated by lights, creating a serene and luxurious atmosphere. These illustrations are commonly used for marketing purposes, architectural presentations, or as part of a resort's promotional materials.
