Three.js 行在 Canvas 渲染器中不起作用，但在 WebGL 渲染器中起作用

Question

我想在非 WebGL 浏览器上使用 Canvas 渲染器，在其他浏览器上使用 WebGL。 我的代码在 webGL 渲染器上运行良好，但在画布渲染器上则无法显示 THREE.Line。

//Edges
var edgeMat = new THREE.LineBasicMaterial({
    color: 0x000000,
    opacity: 0.6
} );

for (var edgeId in graph.edgesl) {

    var nodeInId = graph.edgesl[edgeId];
    var nodeOutId = graph.edgesr[edgeId];

    var edgeGeom = new THREE.Geometry();
    edgeGeom.vertices.push(new THREE.Vertex(nodes[nodeInId].position));
    edgeGeom.vertices.push(new THREE.Vertex(nodes[nodeOutId].position));

    var drawingLine = new THREE.Line( edgeGeom , edgeMat );

    //Store In, Out node ID
    drawingLine.inNodeId = nodeInId;
    drawingLine.outNodeId = nodeOutId;

    nodes[nodeInId].edges.push(drawingLine);
    nodes[nodeOutId].edges.push(drawingLine);

    //Meshes additionally need also dynamic flag enabled (to keep internal typed arrays).
    drawingLine.dynamic = true;

    scene.addObject(drawingLine );

    edges.push(drawingLine);

}

有人对此有什么想法吗？

谢谢你！

从 r45 scene.addObject(drawingLine); 必须现在 scene.add(drawingLine);

这里同样的问题：

Three.js 在 render() 上不缩放或旋转网格
