假设有两个相机根据需求进行切换.
我的想法是设置渲染器切换渲染的相机即可:renderer.render(scene, camera);然后用visible 属性来判断渲染哪一个相机.
以下为参考例子:
<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(); // 场景
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 ); // 摄像机
var camera2 = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 ); // 第二个摄像机
camera2.visible = false;//虽然无效,但是通过这个属性判断渲染那个相机
var renderer = new THREE.WebGLRenderer(); // 渲染器
renderer.setSize( window.innerWidth, window.innerHeight ); // 渲染器宽度
document.body.appendChild( renderer.domElement );
var animate = function () {
requestAnimationFrame( animate ); // 循环渲染
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
if(camera.visible)
{
renderer.render( scene, camera ); // 渲染摄像机1
}
else
{
renderer.render( scene, camera2 );// 渲染摄像机2
}
};
animate();
</script>
</body>
</html>
