The Study Of Estate Modeling And Roaming Display Technology Based On Unity3D

Estate sales is different from other consumer goods,buyers usually purchase houses after obtaining sufficient information and experience.In order to allow buyers to have better information and user experience,it's imperative that use virtual reality technology to carry out digital showroom and 3D roaming display of estate sandbox.3D modeling technology has a pivotal position in 3D roaming display.This article is based on the analysis of virtual reality technology,parametric modeling technology,and roaming display technology,taking estate structure diagram and showroom structure diagram of a district in Xi'an,according to simplified structure diagram of showroom,research vectorization of building image and rapid modeling of manual and automatic model based on Unity3D,and on this basis starts estate roaming display technology rearch,achieved showroom and estate virtual roaming display,which can replace traditional display mode of estate sandbox and showroom.Through parametric modeling method research can accelerate the development of 3D modeling speed,three-dimensional roaming display can let buyers through digital interactive roaming,more intuitive experience to understand the whole picture of the real estate and model,while reducing the cost of real estate publicity.Therefore,research on this topic has a good academic and practical value.The main research work and achievements of this article are as follows:(1)In accordance with the parametric modeling,set up the wall,door,floor,glass and other basic single standard model in 3ds Max first,then import the single model into Unity3D,and the parametric modeling of the showroom is carried out in Unity3D.(2)It proposes a rapid modeling method of vectorization,which is through de-noising and graying,binarization pretreatment,and edge detection,contour extraction method combined with corner detection of showroom simplified structure diagram,extracted feature vector of showroom diagrams,and use parametric mode automatically generated wall models of showrooms in the Unity3D.Then the doors,windows and other models are added with manual parametric modeling,completed the fast three-dimensional showroom parametric modeling.After testing,the effect is good.(3)In the Unity3D,by importing the complexity models which are built based on market structure diagram in 3D modeling software,and the texture of them,and finally establish outdoor 3D scene based on the residential real estate exhibition;By studying and achieving the particle system,sky boxes and collision detection technology,the system of three-dimensional roaming display based on Unity3D is achieved.
