Three.js相机仅聚焦于原始点

Question

I have drawn a path(line) around the origin, i want to move the camera along with line. But the camera is always facing towards the Origin. But as per my Project specification i have to travel along the continuation of the line.]

camera is travelling(camera.Position.set(x,y,z) from A to B in a correct way. but when it is traveling from B to C and C to D etc , camera is facing origin not the Line.My requirement is camera should focus the line not the origin.

Answer 1

Make sure you don't have something like this in your code:

camera.target = new THREE.Vector3(0,0,0);
...
function render(){
    ...
    camera.lookAt(camera.target);
    ...
}

In that case upon reaching point B you should make point C a new camera target.

camera.target = pointC.position.clone();
