纹理形状在three.js中挤出

Question

我正在尝试在Three.js中纹理挤压形状。在下面的代码中，我创建一个弯曲的形状，挤出形状，然后创建一个网格，其中包含几何和我从Jpg文件加载的材质。线框显示但纹理不显示。纹理尺寸为512 * 512px。

我使用正确的方法吗？我是否需要手动UV贴图纹理？我希望纹理能够包裹到整个挤压面而不是每个单独的四边形。

var x = -50, y = 20, z = 150;
var rx = 0, ry = Math.PI/4, rz = 0;
var scale = 1;
var color = 0x00ff00;

var shape = new THREE.Shape();

shape.moveTo( x, y );
shape.quadraticCurveTo(x+50, y, x+100, y+50);
shape.quadraticCurveTo(x+50, y, x, y);      

var texture = new THREE.ImageUtils.loadTexture('images/checkerboard.jpg');        
var material = new THREE.MeshBasicMaterial({ map:texture, doubleSided:true });

/* 3D */
var extrudeSettings = { amount: 100 };
extrudeSettings.bevelEnabled = false;
extrudeSettings.steps = 1;

var geometry = new THREE.ExtrudeGeometry( shape, extrudeSettings );       

//var mesh = new THREE.Mesh( geometry, material );
var mesh = THREE.SceneUtils.createMultiMaterialObject( geometry, [ material, new THREE.MeshBasicMaterial( { color: 0x000000, wireframe: true, transparent: true } ) ] );
mesh.position.set( x, y, z);
mesh.rotation.set( rx, ry, rz );

scene.add( mesh );

ExtrudeGeometry最初用于拉伸字体，它为您创建的UV可能无效。您必须手动提供UV。

检查来源，您会看到可以选择将THREE.ExtrudeGeometry.WorldUVGenerator替换为您自己的。{/ p>
