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/
