多年前本人開始從事三維動(dòng)畫方面的學(xué)習(xí)，后學(xué)習(xí)了PHP，發(fā)現(xiàn)可以通過(guò)PHP動(dòng)態(tài)生成VRML文檔，有點(diǎn)類似于Generator動(dòng)態(tài)生成Flash的方式。
由于VRML博大精深，這里只介紹一個(gè)簡(jiǎn)單的例子，還可以將各種VRML結(jié)點(diǎn)存入數(shù)據(jù)庫(kù)中，這樣的虛擬現(xiàn)實(shí)網(wǎng)頁(yè)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(shí)。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(gè)主頁(yè)上去下載：http://go.163.com/~sjtucaocao/
