X3D 无法识别 <rectangle2d>

Question

当我使用 <Rectangle2D /> 节点时，矩形没有显示在 canvas 上，调试控制台打印警告 WARNING: Unrecognised X3D element <rectangle2d>.。我用 Chrome 67 和 Firefox 61 试了一下，我的代码如下：

<html>
    <head>
        <meta http-equiv="X-UA-Compatible" content="IE=edge" />
        <title>X3DOM page</title>
        <script type='text/javascript' src='https://www.x3dom.org/download/x3dom.js'></script> 
        <link rel='stylesheet' type='text/css' href='https://www.x3dom.org/download/x3dom.css'></link>
    </head>

    <body>
        <X3D width='500px' height='400px'>
            <Scene>
                <Shape>
                    <Appearance DEF='MagentaAppearance'>
                        <Material diffuseColor='0 1 0' />
                    </Appearance>
                    <Rectangle2D ccw='true' lit='true' size='7,7' solid='true'></Rectangle2D>
                </Shape>
            </Scene>
        </X3D>
    </body>
</html>

Answer 1

我发现了问题，对 2d 几何体使用 x3dom-full.js 而不是 x3dom.js。

X3D 无法识别 <rectangle2d>

X3D don't recognise <rectangle2d>
