我在改變THREEJs旋轉方面困難重重。我基本上想讓我的相機圍繞我的物體旋轉,而不是圍繞標準點(0,0,0?)旋轉。其原因是,我的Vector3值是相當大的。(X,Z,Y)ThreeJS改變相機的旋轉焦點

我連接與行中的點,設置攝像機位置的邊框,並使用OrbitalControls走動。但移動相機不關注我的線幾何。我如何改變旋轉行爲?任何人都可以把我放在正確的道路上嗎?
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();
後來,我把我的數據,以幾何...
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);
};
墊,感謝您的時間和答案。我嘗試了兩種方法,但迄今爲止並不幸運。我必須首先添加一個位置到我的線上,對嗎?像'line.position.set(x,y,z);'? –
得到它的工作,我只需要改變'controls.rotateSpeed = 0.3', 'controls.zoomSpeed = 0.2'and'controls.panSpeed = 0.05',它們設置得太慢了。技巧是'controls.target = YourObject.position.clone()'感謝Mat! –
