【中文标题】3D 对象在我的网站中显示为黑色背景【英文标题】:3D object appears with a black background in my website 【发布时间】:2021-10-21 05:23:08 【问题描述】:我从 three.js 中找到了一个 3d 对象,它有一个 404 文本,带有一个浮动球体,而不是零。当我导入它的代码时,它可以工作,但背景是黑色的。我尝试使用这些值并尝试向其容器添加背景颜色,但它不起作用。我也使用了检查器,但没有任何效果。我想让背景透明。
(我也尝试新建一个网站并添加,但出现了同样的问题)
这里是代码
html:
<div class="cont-404">
<p class="mega">4<span class="boom">0</span>4
<div class="bola"></div>
</p>
<p class="mini">That's an error.</p>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r79/three.min.js"></script>
CSS:
.cont-404
float: right;
.mini
font-size: 1em;
color: #fff;
line-height: 9em;
text-indent: 2.5em;
position: absolute;
left: 50%;
top: 50%;
.mega, .bola
line-height: 1.65em;
font-weight: bold;
font-size: 11em;
color: #fff;
font-family: 'Roboto', saappeared
width: 300px;
height: 300px;
position: absolute;
left: 50%;
top: 50%;
margin-left: -150px;
margin-top: -150px;
.boom color: #f5f5f5;
JS:
var $container = $('.bola');
var renderer = new THREE.WebGLRenderer( antialias: true );
var camera = new THREE.PerspectiveCamera(80, 1, 0.1, 10000);
var scene = new THREE.Scene();
scene.add(camera);
renderer.setSize(300, 300);
$container.append(renderer.domElement);
///////////////////////////////////////////////
// Camera
camera.position.z = 200;
// Material
var pinkMat = new THREE.MeshPhongMaterial(
color: new THREE.Color("#C3073F"),
emissive: new THREE.Color("rgb(0,0,0)"),
specular: new THREE.Color("#C3073F"),
shininess: 50,
shading: THREE.FlatShading,
transparent: 1,
opacity: 1
);
var L1 = new THREE.PointLight(0xffffff, 1);
L1.position.z = 100;
L1.position.y = 100;
L1.position.x = 100;
scene.add(L1);
var L2 = new THREE.PointLight(0xffffff, 0.8);
L2.position.z = 200;
L2.position.y = 400;
L2.position.x = -100;
scene.add(L2);
// IcoSphere -> THREE.IcosahedronGeometry(80, 1) 1-4
var Ico = new THREE.Mesh(new THREE.IcosahedronGeometry(75, 1), pinkMat);
Ico.rotation.z = 0.5;
scene.add(Ico);
function update()
Ico.rotation.x += 2 / 100;
Ico.rotation.y += 2 / 100;
// Render
function render()
requestAnimationFrame(render);
renderer.render(scene, camera);
update();
render();
【问题讨论】:
您没有正确发布您的HTML
代码。
现在是正确的还是你的意思是我需要添加 和 ?
看看***.com/questions/16177056/…
非常感谢
var scene = new THREE.Scene(); // initialising the scene scene.background = new THREE.Color( 0xff0000 );
这个代码有帮助
【参考方案1】:
var renderer = new THREE.WebGLRenderer( antialias: true );
像这样创建渲染器:
var renderer = new THREE.WebGLRenderer( antialias: true, alpha: true );
var pinkMat = new THREE.MeshPhongaterial(
错字。应该是MeshPhongMaterial
。
color: new THREE.Color("#C3073F")appearedssive: new THREE.Color("rgb(0,0,0)"),
这行没有意义。试试吧
color: new THREE.Color("#C3073F"),
var $container = $('.bola');
这是您在示例代码中未使用的 jQuery 代码。
这是一个固定的实时示例:
var $container = document.querySelector('.bola')
var renderer = new THREE.WebGLRenderer( antialias: true, alpha: true );
var camera = new THREE.PerspectiveCamera(80, 1, 0.1, 10000);
var scene = new THREE.Scene();
scene.add(camera);
renderer.setSize(300, 300);
$container.append(renderer.domElement);

// Camera

shininess: 50,

);
var L1 = new THREE.PointLight(0xffffff, 1);
L1.position.z = 100;
L1.position.y = 100;
L1.position.x = 100;
scene.add(L1);
var L2 = new THREE.PointLight(0xffffff, 0.8);
L2.position.z = 200;
L2.position.y = 400;
L2.position.x = -100;
scene.add(L2);

var Ico = new THREE.Mesh(new THREE.IcosahedronGeometry(75, 1), pinkMat);
Ico.rotation.z = 0.5;
scene.add(Ico);
function update()
Ico.rotation.x += 2 / 100;
Ico.rotation.y += 2 / 100;
// Render

renderer.render(scene, camera);

【讨论】:
对不起,我认为发生了一些事情弄乱了我的 js 代码我重新复制它并编辑了问题 我已经更新了代码。创建WebGLRenderer
的实例时必须应用alpha
参数。以上是关于3D 对象在我的网站中显示为黑色背景的主要内容,如果未能解决你的问题,请参考以下文章
