Abstract£º Virtual building exhibition on the sand table has
poor detail processing effect of virtual building space due to space constraint£¬ and poor simulation effect of building space due to lack of effective rendering and animation presentation mode. Therefore£¬ a simulation design and implementation method of 3D virtual building space is proposed. During the virtual implementation and simulation design of building space£¬ the position and parameter of the component are used to construct the mathematical model of the building space component based on the constructed building space coordinate and proportional scale. The mathematical model of the whole building space is constructed after fusing mathematical models of various components. The OpenGL virtual reality technology is used to perform extend processing of the target building based on the mathematical model of target building space. The material and texture feature of the target building are given to obtain the optimal 3D virtual view of building space. The 3D rendering for the 3D virtual view of building space is performed to present a vivid 3D virtual effect image of building space. The animation design technology is used to conduct animation display of the 3D virtual effect image of building space. The experimental results show that the proposed design method has good effects of dot?line rendering and whole rendering£¬ can
obtain a vivid simulation design result of 3D virtual building space£¬ and has high interaction and practicability.
