Javascript 具有自定义几何体的网格的Three.js纹理

我正在尝试创建房屋几何体，并将不同的纹理附着到几何体的面上。我正在使用

r55

。问题是，使用从纹理创建的材质的面不会出现。但是，使用简单颜色材质的面不会出现。如果使用简单的颜色材质替换从我的

屋顶纹理生成的材质，则使用该材质的面也会正确显示

以下是我的代码的相关部分：

var geom = new THREE.Geometry();

// Load the roof texture
var roofTexture = new THREE.ImageUtils.loadTexture('gfx/textures/roof.jpg');

// Let the roof texture repeat itself
roofTexture.wrapS = roofTexture.wrapT = THREE.RepeatWrapping;
roofTexture.repeat.set(10, 10);

// Materials
var materialArray = [];
materialArray.push(new THREE.MeshLambertMaterial({color: 0xD3E3F0 }));
materialArray.push(new THREE.MeshLambertMaterial({map: roofTexture}));

// Base edges
var edge0 = new THREE.Vector2(obj.ridgeLength/2, -obj.buildingDepth/2);
var edge1 = new THREE.Vector2(obj.ridgeLength/2, obj.buildingDepth/2);
var edge2 = new THREE.Vector2(-obj.ridgeLength/2, obj.buildingDepth/2);
var edge3 = new THREE.Vector2(-obj.ridgeLength/2, -obj.buildingDepth/2);

// Floor
geom.vertices.push(new THREE.Vector3(edge0.x, -1, edge0.y));
geom.vertices.push(new THREE.Vector3(edge1.x, -1, edge1.y));
geom.vertices.push(new THREE.Vector3(edge2.x, -1, edge2.y));
geom.vertices.push(new THREE.Vector3(edge3.x, -1, edge3.y));

// Eave
geom.vertices.push(new THREE.Vector3(edge0.x, obj.eaveHeight, edge0.y));
geom.vertices.push(new THREE.Vector3(edge1.x, obj.eaveHeight, edge1.y));
geom.vertices.push(new THREE.Vector3(edge2.x, obj.eaveHeight, edge2.y));
geom.vertices.push(new THREE.Vector3(edge3.x, obj.eaveHeight, edge3.y));

// Ridge
geom.vertices.push(new THREE.Vector3(obj.ridgeLength/2, obj.ridgeHeight, 0));
geom.vertices.push(new THREE.Vector3(-obj.ridgeLength/2, obj.ridgeHeight, 0));


// Ground
geom.faces.push( new THREE.Face4(0, 0, 0, 0) );

// Front
geom.faces.push( new THREE.Face4(0, 3, 7, 4) );

// Left side
geom.faces.push( new THREE.Face4(0, 4, 5, 1) );

// Back
geom.faces.push( new THREE.Face4(1, 5, 6, 2) );

// Right side
geom.faces.push( new THREE.Face4(2, 6, 7, 3) );

// Left triangle
geom.faces.push( new THREE.Face3(4, 8, 5));

// Right triangle
geom.faces.push( new THREE.Face3(6, 9, 7));

// Front roof
geom.faces.push( new THREE.Face4(7, 9, 8, 4) );

// Back roof
geom.faces.push( new THREE.Face4(5, 8, 9, 6) );

// Assign materials to the faces
geom.faces[0].materialIndex = 0;
geom.faces[1].materialIndex = 0;
geom.faces[2].materialIndex = 0;
geom.faces[3].materialIndex = 0;
geom.faces[4].materialIndex = 0;
geom.faces[5].materialIndex = 0;
geom.faces[6].materialIndex = 0;
geom.faces[7].materialIndex = 1;
geom.faces[8].materialIndex = 1;

geom.computeFaceNormals();

obj.house = new THREE.Mesh( geom, new THREE.MeshFaceMaterial(materialArray) );
obj.house.doubleSided = true;
obj.house.castShadow = true;
obj.sun.shadowDarkness = 1.0;
obj.scene.add(obj.house);

我做错了什么？
几何体上缺少UV坐标。UV坐标从0到1，因此，由于您自己创建几何体，因此可以在左下角指定右下角（1.0，0.0）、左上角（0.0，1.0）和右上角（1.0，1.0）上的UV（0.0，0.0）。您可以查看PlaneGeometry.js文件以了解UV是如何分配的
 对于那些寻找语法的人来说，它是：
geom.faceVertexUvs[0].push（[new THREE.Vector2（0,0），new THREE.Vector2（0,1），new THREE.Vector2（1,1）]。这将为第一个面的三个顶点指定uv坐标（0,0）、（0,1）、（1,1）。要将uv指定给下一个面，请执行
geom.faceVertexUvs[0]。按（…）。嗨，我还在三个js中创建一个车库。我必须在外墙和内壁上应用不同的纹理。该方法与您类似，创建顶点并向几何体添加面，但一个纹理应用于所有墙，如果我为材质提供一个数组，则该方法无效，甚至连墙都不可见。你找到解决办法了吗？
