3D Rendering and Optimization Algorithm for Landscape Architecture of Digital City

Digital city is to realize digitalization, automation and networking of urban information management, and 3D modeling technology is essential to realize 3D visualization of landscape architecture. Visualization of urban 3D modeling refers to the 3D description and analysis of the space within the urban area through the 3D visualization system, which can realize the combination of visual reality and virtual reality. Due to the rapid growth of sci & tech, 3D visualization technology has been widely used. Because landscape design, regardless of scale, hopes to achieve the effect of one scene at a time and the landscape moves with the pace in spatial organization, it is very important for designers to show the design works in an all-round, real and even dynamic way, which will help to accurately express the design ideas of landscape designers. The simulation results show that the comprehensive performance of 3D landscape drawing and optimization algorithm based on artificial intelligence and computer aided design (CAD) has obvious advantages compared with traditional landscape planning methods, which can provide reference for related research. © 2024 CAD Solutions, LLC.
