Graphic images of computer three-dimensional simulation technology are widely used in the construction industry. Technical applications mainly include 3D simulation software and some 3D modeling tools. In the application field, there are simulation simulations of industrial architecture and interior design, urban landscape design, and demonstration simulations during construction. Based on the computer simulation technology, this thesis made a 3D simulation model with a sense of reality. Based on the calculation amount of the computer system model surface and the calculation amount of basic map texture resources, the production of the model was completed. 3D simulated points, lines, surfaces and various levels of polygonal forms. As a result, the accuracy of the spatial element layout optimization model becomes lower and the convergence speed becomes slower. A reasonable layout simulation method for landscape space elements is proposed. Selected patch area, landscape percentage, patch number, maximum patch index and average patch area as the browsing index. Use Ahp to calculate the weight of the above landscape index, and use the matching test to change and adjust the judgment result. The results show that the proposed 3D simulation model has excellent visual effects, can clearly reflect all design elements of landscape design, and its high precision and high convergence rate can be effectively applied to urban landscape design.
