Smart City Construction and Rendering Based on Virtual City Space

In response to the cultural development strategy put forward by my country in the past two years, this paper combines virtual reality technology with unique rendering technology, uses texture mapping technology to construct virtual city roaming scenes, ray tracing algorithm creates various lighting rendering effects, and dynamic image algorithm realizes images Sharpen, automatically adjust the brightness of the texture. Through the above technology, the ancient style and modernity are merged to create a quiet and elegant future virtual architectural scene.
