多年前本人开始从事三维动画方面的学习,后学习了PHP,发现可以通过PHP动态生成VRML文档,有点类似于Generator动态生成Flash的方式。 由于VRML博大精深,这里只介绍一个简单的例子,还可以将各种VRML结点存入数据库中,这样的虚拟现实网页将……,爽! 下面是源程序。注意:在服务器上,要将让PHP处理wrl格式的文档,否则后果将是没有任何虚拟现实。本源程序直接存成wrl文件,在浏览器中要安装插件,可以到我的另一个主页上去下载:http://go.163.com/~sjtucaocao/ <?php header("Content-type: application/x-vrml");$txt="#VRML V2.0 utf8
