blender+Three.js 三维数据可视化：数字孪生
原来叫做系统仿真现在都叫做数字孪生了，我也凑个热闹，这个是一个仓库提货的场景仿真。延续上一个项目《blender+Three.js 三维数据可视化》2和3，有兴趣的可以去看。
环境：blender-2.93.6-windows-x64+Three.js 0.91.0+Echart2.0
这里是上一个场景的仓库部分，出货分为发货（直接从厂里发到客户，走内部流程）和自提（客户自己来取货），这里是自提部分，主要是这个自动装货机是我们项目的，所以借此机会客户加了一个这个需求。
废话说完，我们开始，首先分析需求和流程：
1、客户每天需要装车的订单是一个全集，这个全集会变化，我们5分钟更新一次；
2、拿到装货单排队等待的是一个子集，他们会入场等待；
3、有4个装卸口，4个自动装货机，每次装卸操作会记录装货的条码，可以通过条码得到品类、重量什么的信息；
需要模拟场景，拿到装货单的订单入场等待（模拟成一辆汽车，实际可能不止），在装卸口排队的或者装车的，模拟成装卸（车停在装卸口并且机械臂运动），装卸完成的，走人。
用blender创建仓库模型，用THREE.js加载进来。

主要是把停车位、机械臂和装卸口用数组保存起来，数组定义如下：
var orderObjects=[]; //订单信息
var parks=[]; //车位信息
var currentParkOrder=null; //当前进行停车场动画的订单
var handArr=[]; //机械臂
var workAreaArr=[]; //装卸口信息
var currentLoadOrder=null; //当前进行装卸口停车的订单
var currentOverOrders=[]; //出库的订单列表
然后是处理停车、进入装卸口和离场的动画部分：
/取得一个新的订单对象
function getOrderObject(id)
{
var orderObject={};
var object=new THREE.Group();
var truck=newOrderTruck.clone();
truck.position.set(0,0,0);

}在桢刷新时候调用（或者写一个定时器，这个比较稳定）
function animate_Frame()
{
animateOrder();
renderer.render(scene, camera);
requestAnimationFrame(animate_Frame);
}
主要的思路就是，在场景中放置标志点，然后将标志点连接成路径，均分为多少份，每次移动一个标志点的位置。
var curvePath=[];
var point=currentLoadOrder.points[currentLoadOrder.pointIndex-1];
curvePath.push(new THREE.Vector3(point.x,point.y,point.z));
point=currentLoadOrder.points[currentLoadOrder.pointIndex];
curvePath.push(new THREE.Vector3(point.x,point.y,point.z));
var curve = new THREE.CatmullRomCurve3(curvePath);
currentLoadOrder.path=curve;
currentLoadOrder.progress=0;取两个点生成一个路径。
currentLoadOrder.progress += 0.008;
var point = currentLoadOrder.path.getPoint(currentLoadOrder.progress);
...
currentLoadOrder.object.position.set(point.x,point.y,point.z);
根据点密度，调整这个progress，实现快或者慢的效果。
掉头主要是根据点的位置来计算，例如：
if(currentLoadOrder.pointIndex==2 && currentLoadOrder.object.rotation.y>- Math.PI / 2)
{
currentLoadOrder.object.rotation.set(0,currentLoadOrder.object.rotation.y-0.02,0);
}
实现左转。
