问题描述：

导出模型时

three.js所版本创建额外的面孔在我的Three.js场景中它们究竟是如何出现在Blender中的。这是我可以将它们用作模型的轮廓边框。例如，这里是默认的立方体的线框模型是有当您启动搅拌器：three.js所从搅拌机

这里是JSON这种模式后，我出口它：

    "colors": [] 
}

公告如何有6面。我希望它在我的Three.js场景中完全像这样。然而，额外的面孔被绘制。这通常是因为Three.js连接了Blender中没有连接的顶点。下面是它的外观后，我将其加载到我的场景：

见http://stackoverflow.com/questions/20153705/three-js-wireframe-material-all-polygons-vs-just-edges/20154589#20154589 – WestLangley

从这答案，我用** ** THREE.EdgesHelper像这样： '变种EGH =新THREE.EdgesHelper（目，0x00ffff）; egh.material.linewidth = 2; scene.add（EGH）;' 这工作，所以请注明随着你的答案，我会接受它=） –

答

要渲染的线框模式，但没有对角线立方体或盒子。要做到这一点

一种方法是用EdgesHelper，就像这样：

var helper = new THREE.EdgesHelper(mesh, 0xff0000); 
helper.material.linewidth = 2; 
scene.add(helper);
