虽然这已成为一个主题,但尚未得到回答.我收到以下导入错误我刚刚从EPD安装了机盖,在我安装它之后,它不断出现以下错误:

我试图制作一个显示许多球形对象的三个 js 文档，最快的方法是使用缓冲区几何。从这里的这篇文章中，我了解到我可以使用以下方法将普通几何体转换为缓冲几何体：

    var sphere = new THREE.SphereGeometry( 4, 0.05, 0.025 );
    var geometry = THREE.BufferGeometryUtils.fromGeometry( sphere );

但这对我来说似乎不起作用，创建对象的其余代码如下：

    var positions = new Float32Array( x_GAMA.length * 3 );


    for ( var i = 0; i < x_GAMA.length; i += 1 ) {

                // positions

                positions[ 3*i ]     =  x_GAMA[i]*10000;
                positions[ 3*i + 1 ] =  y_GAMA[i]*10000;
                positions[ 3*i + 2 ] =  z_GAMA[i]*10000;



            }
    geometry.addAttribute( 'position', new THREE.BufferAttribute( positions, 3 ) );

    var material = new …
