摘    要

隨著虛擬現(xiàn)實(shí)技術(shù)的不斷發(fā)展，在虛擬現(xiàn)實(shí)場景中實(shí)現(xiàn)漫游成為一種可能，模擬環(huán)境在現(xiàn)實(shí)生活中的應(yīng)用成為人們?cè)絹碓疥P(guān)注的課題。它在各個(gè)行業(yè)和領(lǐng)域中的運(yùn)用預(yù)示著其美好發(fā)展前景。GIS地理信息系統(tǒng)的開發(fā)與應(yīng)用是它的一個(gè)分支。本文重點(diǎn)以學(xué)校地理信息系統(tǒng)的構(gòu)建展開研究基于3DMAX建模方法與技巧，建模步驟分為現(xiàn)場考察攝影，收集整理材料，立體模型的構(gòu)建，賦予材質(zhì)貼圖，設(shè)置燈光與相機(jī)，以及運(yùn)用AutoCAD、Photoshop、lightscape進(jìn)行輔助設(shè)計(jì)和后期處理生成立體效果圖。

ABSTRACT
Along with the virtual reality technical unceasing development, realizes in the virtual reality scene roams into one kind of possibility, the simulated environment the topic which more and more pays attention in real life application into people. It indicates its happy prospects for development in each profession and the domain utilization. The GIS geographic information system development and the application are its branch. This article key constructs by the school geographic information system launches the research based on the 3DMAXmodelling method and the skill, the modelling step divides into the scene inspection photography, the collection reorganization material, three-dimensional model constructing, entrusts with the material quality to paste the chart, the establishment light and the camera, as well as using AutoCAD, Photoshop, lightscape carries on the assistance design and the later period processes the production three-dimensional effect chart.

Key words: Virtual Reality；3DMAX；Three dimensional modelling； Roaming； Geographic Information System
