行星轨迹制作_用3ds max制作三维行星运动动画 3ds max是一款广泛用于建筑、装饰、机械设计、模具制造等行业的专用软件，用它不仅可以制作形象逼真的物理模型，而且能够创作精巧的三维空间动画，用它来制作物理课件，可谓是巧夺天工．现以人教版新教材必修2第七章第1节行星的运动为例，展示用3ds max制作三维动画课件无与伦比的优越性．万有引力定律教学是通过分析太阳系行星的运动规律逐渐深入的．由于行星的运动我们我无法直接观察，要让学生了解行星的运行特... 阅读详情

AI摘要

本文详细介绍了如何在Vue应用中安装和配置Mars3D库，实现三维地球场景的创建，以及如何通过TLE数据展示卫星轨迹。涵盖了主库安装、Cesium模块引入、配置文件设置、组件使用和卫星列表生成等内容。

1、安装

//安装mars3d主库
npm install mars3d --save

2、引入
main,js

import 'mars3d/dist/mars3d.css'
import * as mars3d from 'mars3d'
~~mars3d-space不引入，无法使用卫星的功能~~ 
import 'mars3d-space'
Vue.prototype.mars3d = mars3d;

vue.config.js
