多年前本人開始從事三維動畫方面的學習，后學習了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; ?> ;;;;;
