Javascript 三个JS圆删除

杜布先生在他的论坛/网站上添加了这一点，以创建圈子

var resolution = 100;
var amplitude = 100;
var size = 360 / resolution;

var geometry = new THREE.Geometry();
var material = new THREE.LineBasicMaterial( { color: 0xFFFFFF, opacity: 1.0} );
for(var i = 0; i <= resolution; i++) {
    var segment = ( i * size ) * Math.PI / 180;
    geometry.vertices.push( new THREE.Vertex( new THREE.Vector3( Math.cos( segment ) * amplitude, 0, Math.sin( segment ) * amplitude ) ) );         
}

var line = new THREE.Line( geometry, material );
scene.add(line);

var分辨率=100；
var振幅=100；
变量大小=360/分辨率；
var geometry=new THREE.geometry（）；
var material=新的三线基本材质（{颜色：0xFFFFFF，不透明度：1.0}）；
对于（var i=0；i您没有添加单独的对象。所有这些顶点都属于同一个对象，因此您不能简单地删除它们。您需要做的是：

    for (var i = 0; i <= resolution; i++) {
        var segment = (i * size) * Math.PI / 180;
        geometry.vertices.push(new THREE.Vertex(new THREE.Vector3((Math.cos(segment) * amplitude) +  (moves[move][move + '_mrfoot0'][0][0] * scale)-30, 0, (Math.sin(segment) * amplitude) + 375)));
    }

    feetcircle = new THREE.Line(geometry, new THREE.LineBasicMaterial({
        color: 0x00ff00, opacity: 1.0
    }));
    feetcircle.geometry.dynamic = true;
    scene.add(feetcircle);

    geometry = new THREE.Geometry();
    for (var i = 0; i <= resolution; i++) {
        var segment = (i * size) * Math.PI / 180;
        geometry.vertices.push(new THREE.Vertex(new THREE.Vector3((Math.cos(segment) * amplitude) +  (moves[move][move + '_mrfoot0'][0][0] * scale)-30, 410, (Math.sin(segment) * amplitude) + 375)));
    }

    var feetcircle2 = new THREE.Line(geometry, new THREE.LineBasicMaterial({
        color: 0x00ff00, opacity: 1.0
    }));
    feetcircle2.geometry.dynamic = true;
    scene.add(feetcircle2);

    ...
    scene.remove(feetcircle);
    scene.remove(feetcircle2);

for（var i=0；我向我们展示了您编写的代码。那里的代码只创建了一个圆圈。我编辑了我的初始消息：）

    }
