[英]ThreeJS change rotation focus of Camera
我很難改變THREEjs的旋轉角度。 我基本上希望我的相機繞我的對象旋轉,而不是繞標准點(0,0,0?)旋轉。 原因是我的Vector3值相當大。.(x,z,y)

我將點與線連接起來,將相機位置設置為邊界框,並使用OrbitalControls來移動。 但是移動相機並不會專注於我的線條幾何。 如何更改輪換行為? 誰能把我放在正確的道路上?
var renderer,
scene,
camera,
controls
renderer = new THREE.WebGLRenderer({ antialias: true });
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.setClearColorHex( 0xeeeeee, 1.0 );
scene = new THREE.Scene();
var material = new THREE.LineBasicMaterial({
color: 0xff00cc,
fog: true
});
var geometryL = new THREE.Geometry();
之后,我將數據推送到幾何...
var line = new THREE.Line(geometryL, material);
geometryL.computeBoundingBox();
var bBox = geometryL.boundingBox;
console.log(bBox);
var x_max = bBox.max.x;
var y_max = bBox.max.y;
var z_max = bBox.max.z;
scene.add( line );
camera = new THREE.PerspectiveCamera( 60, window.innerWidth / window.innerHeight, 1, 5000000);
camera.position.set( x_max*1.01, y_max*1.01, z_max*1.01 );
controls = new THREE.OrbitControls( camera );
controls.addEventListener( 'change', animate );
controls.rotateSpeed = 0.01;
controls.zoomSpeed = 0.01;
controls.panSpeed = 0.08;
controls.noZoom = false;
controls.noPan = false;
controls.staticMoving = true;
controls.dynamicDampingFactor = 2;
animate();
function animate() {
renderer.render( scene, camera );
};
只需將相機應旋轉的對象的位置添加到相機的位置即可。
camera.position.set( x_max*1.01, y_max*1.01, z_max*1.01 ).add(YourObject.position.clone());
您也可以嘗試更改控件的目標:
controls.target = YourObject.position.clone();
希望我對您的理解正確,因為我目前無法運行您的代碼。
