多年前本人開始從事三維動畫方面的學(xué)習(xí)，后學(xué)習(xí)了PHP，發(fā)現(xiàn)可以通過PHP動態(tài)生成VRML文檔，有點類似于Generator動態(tài)生成Flash的方式。;;由于VRML博大精深，這里只介紹一個簡單的例子，還可以將各種VRML結(jié)點存入數(shù)據(jù)庫中，這樣的虛擬現(xiàn)實網(wǎng)頁將……，爽！;;下面是源程序。注意：在服務(wù)器上，要將讓PHP處理wrl格式的文檔，否則后果將是沒有任何虛擬現(xiàn)實。本源程序直接存成wrl文件，在瀏覽器中要安裝插件，可以到我的另一個主頁上去下載：http://go.163.com/~sjtucaocao/;;<?php header("Content-type: application/x-vrml");$txt="#VRML V2.0 utf8;;DEF leftBox Transform;;{;;translation -5 0 0;;children;;[;;Shape;;{;;appearance Appearance;;{;;material Material;;{;;diffuseColor 1 0 0;;};;};;geometry Box{};;};;DEF SphereChild Shape;;{;;appearance Appearance;;{;;material Material;;{;;diffuseColor 1 0 1;;};;};;geometry Sphere;;{;;radius 1.2;;};;};;];;};;DEF rightBox Transform;;{;;translation 5 0 0;;children;;[;;Shape;;{;;appearance Appearance;;{;;material Material;;{;;diffuseColor 0 0 1;;};;};;geometry Box{};;};;];;};;DEF onoff Transform;;{;;translation 0 -1 0;;children;;[;;Shape;;{;;appearance Appearance;;{;;material Material;;{;;diffuseColor 0 1 0;;};;};;geometry Box{};;};;DEF TS TouchSensor{};;];;};;DEF S Script;;{;;eventIn SFBool isActive;;eventOut MFNode child;;field MFNode testNode USE SphereChild;;url;;"javascript:;;function isActive(value);;{;;if (value);;{;;child=testNode;;;};;};;";;};;ROUTE TS.isActive TO S.isActive;;ROUTE S.child TO leftBox.removeChildren;;ROUTE S.child TO rightBox.addChildren";echo $txt;;;?>;;;
