Threejs从高度图变形网格

Question

如何在three.js中使用高度图变形已创建的网格？我做了一些搜索，但找不到任何东西，所以我在这里问。

You are lucky, three.js-r72 introduced vertex displacement in the MeshPhongMaterial. You set the displacement map like a normalMap:

var displacementMap = THREE.ImageUtils.loadTexture( "textures/ninja/displacement.jpg" );

var material = new THREE.MeshPhongMaterial( {
                color: 0x0a0100,
                //...
                displacementMap: displacementMap,
                displacementScale: 2.436143,
                displacementBias: - 0.428408,
            } );

scale: The amount of displacement, "how tall are your spikes"

bias: Shift the center up or down
