本文介绍了如何改变CubeGeometry的宽度与three.js所?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个立方体的几何形状和一个网格,我不知道如何改变宽度(或高度......我可以改变的x,y和z虽然)。
这里是什么我现在一个片段:

 几何=新THREE.CubeGeometry(200,200,200);
材料=新THREE.MeshBasicMaterial({颜色:为0xFF0000,线框:真});
目=新THREE.Mesh(几何形状,材料);
// WebGL的渲染在这里功能渲染(){
    mesh.rotation.x + = 0.01;
    mesh.rotation.y + = 0.02;
    renderer.render(场景,摄像头);
}功能changeStuff(){
    mesh.geometry.width = 500; //不工作。
    mesh.width = 500; //不工作。
    geometry.width = 500; //不工作。
    mesh.position.x = 500 //作品!    渲染();
}

谢谢!

修改

找到了解决方法:

  mesh.scale.x = 500;


解决方案

刚完成意见和问题的解决(并有一个答案present与例如code):

  //创建一个立方体,1个单位的宽度,高度,深度
VAR几何=新THREE.CubeGeometry(1,1,1);//每个立方体方得到另一种颜色
VAR cubeMaterials = [
    新THREE.MeshBasicMaterial({颜色:0x33AA55,透明:真实的,不透明度:0.8})
    新THREE.MeshBasicMaterial({颜色:0x55CC00,透明:真实的,不透明度:0.8})
    新THREE.MeshBasicMaterial({颜色:0x000000处,透明:真实的,不透明度:0.8})
    新THREE.MeshBasicMaterial({颜色:0x000000处,透明:真实的,不透明度:0.8})
    新THREE.MeshBasicMaterial({颜色:0x0000FF,透明:真实的,不透明度:0.8})
    新THREE.MeshBasicMaterial({颜色:0x5555AA,透明:真实的,不透明度:0.8})
];
//创建一个MeshFaceMaterial,允许立方体对每一面不同的材料
VAR cubeMaterial =新THREE.MeshFaceMaterial(cubeMaterials);
VAR立方=新THREE.Mesh(几何,cubeMaterial);cube.position.set(0,0,0);
scene.add(立方体);
cube.scale.x = 2.5; // SCALE
cube.scale.y = 2.5; // SCALE
cube.scale.z = 2.5; // SCALE

在这里实现稍微高级的,动态的例子: http://www.echteinfach.tv/ formeln /几何学/ quader / (仍然是相同的缩​​放)

I have a cube geometry and a mesh, and i don't know how to change the width (or height... i can change x, y and z though). Here's a snippet of what i have right now:

geometry = new THREE.CubeGeometry( 200, 200, 200 );
material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );
mesh = new THREE.Mesh( geometry, material );
// WebGL renderer here

function render(){
    mesh.rotation.x += 0.01;
    mesh.rotation.y += 0.02;
    renderer.render( scene, camera );
}

function changeStuff(){
    mesh.geometry.width = 500; //Doesn't work.
    mesh.width = 500; // Doesn't work.
    geometry.width = 500; //Doesn't work.
    mesh.position.x = 500// Works!!

    render();
}

Thanks!

EDIT

Found a solution:

mesh.scale.x = 500;

解决方案

Just to complete comment and solution from question (and have an answer present with example code):

// create a cube, 1 unit for width, height, depth
var geometry = new THREE.CubeGeometry(1,1,1);

// each cube side gets another color
var cubeMaterials = [ 
    new THREE.MeshBasicMaterial({color:0x33AA55, transparent:true, opacity:0.8}),
    new THREE.MeshBasicMaterial({color:0x55CC00, transparent:true, opacity:0.8}), 
    new THREE.MeshBasicMaterial({color:0x000000, transparent:true, opacity:0.8}),
    new THREE.MeshBasicMaterial({color:0x000000, transparent:true, opacity:0.8}), 
    new THREE.MeshBasicMaterial({color:0x0000FF, transparent:true, opacity:0.8}), 
    new THREE.MeshBasicMaterial({color:0x5555AA, transparent:true, opacity:0.8}), 
]; 
// create a MeshFaceMaterial, allows cube to have different materials on each face 
var cubeMaterial = new THREE.MeshFaceMaterial(cubeMaterials); 
var cube = new THREE.Mesh(geometry, cubeMaterial);

cube.position.set(0,0,0);
scene.add( cube );
cube.scale.x = 2.5; // SCALE
cube.scale.y = 2.5; // SCALE
cube.scale.z = 2.5; // SCALE

A slightly advanced, dynamic example implemented here: http://www.echteinfach.tv/formeln/geometrie/quader/ (still the same scaling)
