Question

我知道如何在三js中动态地创建网格, 但不清楚如何在网格中添加自定义的紫外线和正常的网格。这里如何创建自定义网格, 我们如何在编程中添加紫外线和正常的网格?

谢谢!

var imgTexture = THREE.ImageUtils.loadTexture(image);
var avatarGeom = new THREE.Geometry();

avatarGeom.vertices.push(new THREE.Vector3(0.895813,0.732893,0));
avatarGeom.vertices.push(new THREE.Vector3(-1.007173,0.732893,0));
avatarGeom.vertices.push(new THREE.Vector3(0.895813,-1.390674,0));
avatarGeom.vertices.push(new THREE.Vector3(-1.007173,-1.390674,0));

var face = new THREE.Face3(2,3,1);
avatarGeom.faces.push(face);

face = new THREE.Face3(0,2,1);
avatarGeom.faces.push(face);

var avatar = new THREE.Mesh(avatarGeom,new THREE.MeshLambertMaterial(imgTexture));
avatar.doubleSided = true;
scene.add(avatar);

正常情况在“http://mrdoob.github.com/ three.js/docs/49/#face4'>face 。紫外线在>。

var imgTexture = THREE.ImageUtils.loadTexture(image);
var avatarGeom = new THREE.Geometry();

avatarGeom.vertices.push(new THREE.Vector3(0.895813,0.732893,0));
avatarGeom.vertices.push(new THREE.Vector3(-1.007173,0.732893,0));
avatarGeom.vertices.push(new THREE.Vector3(0.895813,-1.390674,0));
avatarGeom.vertices.push(new THREE.Vector3(-1.007173,-1.390674,0));

var face = new THREE.Face3(2,3,1);
face.normal.set(0,0,1); // normal
avatarGeom.faces.push(face);
avatarGeom.faceVertexUvs[0].push([new THREE.UV(1,1),new THREE.UV(0,1),new THREE.UV(1,0)]); // uvs

face = new THREE.Face3(0,2,1);
face.normal.set(0,0,1); // normal
avatarGeom.faces.push(face);
avatarGeom.faceVertexUvs[0].push([new THREE.UV(0,0),new THREE.UV(1,1),new THREE.UV(1,0)]); // uvs

var avatar = new THREE.Mesh(avatarGeom,new THREE.MeshLambertMaterial(imgTexture));
avatar.doubleSided = true;
scene.add(avatar);

紫外线进入几何的原因是因为这样我们可以有不同的渠道(不同的紫外线组对相同的几何组不同)。
