我正在使用three.js r67,顶点似乎没有更新.我订了geometry.dynamic = true,geometry.verticesNeedUpdate = true.圆正在移动,但线是静态的....

有人可以帮帮我吗？

var scene = new THREE.Scene();
var renderer = new THREE.WebGLRenderer();

var g = new THREE.CircleGeometry( 4, 16 );
var m = new THREE.MeshBasicMaterial({color: 0x114949});
var circle = new THREE.Mesh( g, m );

circle.position.x = 2;
circle.position.y = 2;
circle.position.z = -1;
scene.add( circle );

var material = new THREE.LineBasicMaterial({color: 0xDF4949, linewidth: 5});

var geometry = new THREE.Geometry();
geometry.vertices.push(new THREE.Vector3(0, 0, 0));
geometry.vertices.push(new THREE.Vector3(1, 1, 0));
geometry.verticesNeedUpdate = true;
geometry.dynamic …
