如何围绕世界轴旋转物体而不是物体本身? 我找到了答案,但没有任何对我有用。
如果旋转我想要旋转,那么我制作了一个层次结构,使它看起来有点像波浪。不幸的是,尽管我已经检查并测试了我的所有角度,但它的摇摆不同,我不能让它保持正常。
以下是我正在使用的功能:
function spinThePortal(portal, axis, speed, rotation) {
if (axis === 0) {
portal.rotation.y += speed;
} else {
portal.rotation.x += speed;
}
setTimeout(function () {spinThePortal(portal, axis, speed, rotation);}, 50);
}
function createPortals(firstDoubleCoor, secondDoubleCoor, number) {
var direction = 1, notDirection = 0;
if (firstDoubleCoor[0][0] === firstDoubleCoor[1][0]) {
direction = 0; //vertical lines
notDirection = 1;
}
var amount = difference(firstDoubleCoor[0][notDirection], firstDoubleCoor[1][notDirection]);
var material = new THREE.MeshBasicMaterial({color: portalColorList[number]});
var block = new THREE.CubeGeometry(baseSize / 20, baseSize / 20, baseSize / 20);
function squiggle(coor) {
var root = new THREE.Mesh(block, material);
root.position.set(coor[0][0] * baseSize, coor[0][1] * baseSize, baseSize);
var parent = root;
for (var i = 0; i < amount * 43; i++) {
object = new THREE.Mesh(block, material);
object.position.x = baseSize / 30;
parent.add(object);
parent = object;
}
scene.add(root);
root.traverse(function(object) {
object.rotation.set(Math.PI / 10, Math.PI / 10, 0);
});
if (direction === 1) root.rotation.set(0, 0, -Math.PI / 4);
else root.rotation.set(0, 0, Math.PI / 4);
if (spinPortals) spinThePortal(root, direction, portalSpinSpeed, 0);
}
squiggle(firstDoubleCoor);
squiggle(secondDoubleCoor);
}
