假設有兩個相機根據需求進行切換.
我的想法是設置渲染器切換渲染的相機即可:renderer.render(scene, camera);然後用visible 屬性來判斷渲染哪一個相機.
以下爲參考例子:
<html>
<head>
<title>My first three.js app</title>
<style>
body { margin: 0; }
canvas { width: 100%; height: 100% }
</style>
</head>
<body>
<script src="../static/three.js-master/build/three.js"></script>
<script>
var scene = new THREE.Scene(); // 場景
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 ); // 攝像機
var camera2 = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 ); // 第二個攝像機
camera2.visible = false;//雖然無效,但是通過這個屬性判斷渲染那個相機
var renderer = new THREE.WebGLRenderer(); // 渲染器
renderer.setSize( window.innerWidth, window.innerHeight ); // 渲染器寬度
document.body.appendChild( renderer.domElement );
var animate = function () {
requestAnimationFrame( animate ); // 循環渲染
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
if(camera.visible)
{
renderer.render( scene, camera ); // 渲染攝像機1
}
else
{
renderer.render( scene, camera2 );// 渲染攝像機2
}
};
animate();
</script>
</body>
</html>
