重复凹凸贴图
Dre*_*kes 3 javascript webgl three.js bump-mapping
我正在尝试将凹凸贴图应用于平面,以使用Three.js r55创建一个模糊的感觉表面.
这是我的代码:
var mapHeight = THREE.ImageUtils.loadTexture("images/felt.png");
mapHeight.repeat.set(2, 2);
mapHeight.wrapS = mapHeight.wrapT = THREE.RepeatWrapping;
mapHeight.format = THREE.RGBFormat;
var groundMaterial = new THREE.MeshPhongMaterial({
ambient: 0x008800, color: 0x008800, specular: 0x888888,
shininess: 25, bumpMap: mapHeight, bumpScale: 10, metal: false
} );
scene.add(new THREE.Mesh(new THREE.PlaneGeometry(0.3, 0.3), groundMaterial));
注意我如何设置纹理沿x/y轴重复两次.然而,我所看到的仅在一个象限中应用纹理:
我希望这可以用夹子/重复包装(或者不管它叫什么),但我在RepeatWrapping这里要求.
如何在平面上正确重复凹凸贴图重复任意次数.
编辑 - 完整代码
我着手制作一个简单的复制案例.这是非常小的并且再现下面的图像(从略微不同的摄像机角度.)输出具有相同的问题.
