我想要得到一个三角形的点围绕着一个点,在这个点上,面将指向指定的法线方向。我将使用THREE.js将它们添加到BufferGeometry中。 非常粗糙的图画: ? 以下是我到目前为止拥有的代码: //The XYZ location of a point:
var x = model.points[i*3];
var y = model.points[i*3+1];
var z = model.points[i*3+2];
//The normal vector direction:
var nx = model.normals[i*3];
var ny = model.nor
我试图复制这样的效果:
我想把飞机的顶点简单地动画到我提供的链接上。我知道它是用正弦波传播来实现的,但我不知道如何从平面的中心点开始运动。现在,我有这样的事情
(function drawFrame(ts){
window.requestAnimationFrame(drawFrame);
var vLength = plane.geometry.vertices.length;
for (var i = 0; i < vLength; i++) {
var v = plane.geometry.vertices[i];
v.z = Math.sin(ts /
我有一个从meshlab导出的3D模型,并希望将其加载到three.js中,如下所示:
var scene = new three.Scene();
scene.background = new THREE.Color( 0xffffff );
var camera = new three.PerspectiveCamera(75, window.innerWidth/window.innerHeight, 0.1, 1000);
var renderer = new three.WebGLRenderer({ alpha: true });
renderer.setSize(window.
你好,我看到了为列表视图制作缩放动画的代码
public class ViewAnimation extends Animation {
float centerX, centerY;
public ViewAnimation3(){}
@Override
public void initialize(int width, int height, int parentWidth, int parentHeight) {
super.initialize(width, height, parentWidth, parentHeight);
centerX = width/2.0f;
center
我正在尝试使用node.js和three.js在服务器上导入OBJ (尝试不同)-我在解析文件后收到此错误。这是我导入几何体的当前代码:
var loader = new THREE.OBJLoader();
loader.load(modelPath, function (geometryObj) {
var materialObj = new THREE.MeshBasicMaterial( { vertexColors: THREE.FaceColors, overdraw: 0.5 } );
mesh = new THREE.Mesh(geometryO
我用bower install threejs安装了three.js。
然后,我希望在我的页面中有three.js,所以我的app.js文件以:
define(["jquery", "three"], function() {
"use strict";
然而,当我的页面加载时,Chrome控制台显示:
Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:9000/scripts/three.js
