three.js补间对象到摄像头的前面 [英] three.js tween object to front of camera

问题描述

我有一个物体正在使用WestLangleys回答另一个问题（几乎）很好地过渡到相机的前面：

I've got an object that is tweening (almost) nicely to the front of the camera using WestLangleys answer to another question:

    var pLocal = new THREE.Vector3( 0, 0, -10 );
    var pWorld = pLocal.applyMatrix4( camera.matrixWorld );
    var target = pWorld.sub( camera.position ).normalize();

    var tweenMove = new TWEEN.Tween(object.position).to(target, 2000)

我正在努力的下一部分是使对象与相机保持一定距离（调整z = -10无效），因为完成补间时它会消失（太近了）

The next part I'm struggling with is to get the object to remain a certain distance from the camera (adjusting the z = -10 has no effect), as when it finishes the tween it disappears (too close to camera).

Camera.near is1。

Camera.near is 1.

有什么想法吗？

推荐答案

var pLocal = new THREE.Vector3( 0, 0, - 10 );

var target = pLocal.applyMatrix4( camera.matrixWorld );

var tweenMove = new TWEEN.Tween( object.position ).to( target, 2000 );
