THREE.LineDashedMaterial - 破折号不起作用

Question

我无法THREE.LineDashedMaterial在三个js中正常工作(我正在使用r73,但刚刚尝试过r74).改变颜色很好,但破折号似乎不起作用.这是我的例子:

var segmentCount = 200;
var radius = 100;
var geometry = new THREE.Geometry();
var material = new THREE.LineDashedMaterial( { color: 0xff0000, linewidth: 5, dashSize: 1.0, gapSize: 0.5 } ); //new THREE.LineBasicMaterial({ color: 0xFFFFFF, linewidth: 10 });

for (var i = 0; i <= segmentCount; i++) {
var theta = (i / segmentCount) * Math.PI * 2;
geometry.vertices.push(
    new THREE.Vector3(
        Math.cos(theta) * radius,
        Math.sin(theta) * radius,
        0));            
}


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

我在我的例子中做错了什么,或者这个错误(https://github.com/mrdoob/three.js/issues/6699)仍然是一个问题？

Answer 1

如果您使用THREE.Geometry和 创建一条线路THREE.LineDashedMaterial,则需要拨打电话

line.computeLineDistances(); // or lineSegments.computeLineDistances()

让虚线正确渲染.
