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 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; ?>
