:snowflake: Mission

Our mission is to create the leading 3D globe and map for static and time-dynamic content, with the best possible performance, precision, visual quality, platform support, community, and ease of use.

Apache 2.0. CesiumJS is free for both commercial and non-commercial use.

:earth_americas: Where Does the 3D Content Come From?

CesiumJS can stream 3D content such as terrain, imagery, and 3D Tiles from the commercial Cesium ion platform and other content sources. You are free to use any combination of content sources with CesiumJS that you please. Using Cesium ion helps support CesiumJS development. :heart:

步骤

  1. 安装 nodejs 内网地址:"\192.168.11.11\Share3D\共享工具\编程工具\Web\node-v10.15.3-x64.msi"

  2. 安装依赖库

npm  install
  1. 组织编译
npm run build
  1. 生成合并但未压缩库(自己调试用)
npm run release
  1. 生成 合并压缩混淆(对外发行版)
npm run minifyRelease
  1. 生成说明文档
npm run generateDocumentation
  1. shader 代码中 uniform 变量数量说明
以如下电脑参数为例,使用uniform变量时,整体数量上限约为170,表现为
uniform sampler2D colorTexture;    代表一个uniform变量
uniform float u_factor;            代表一个uniform变量
uniform vec2 u_positionArray[64];  数组长度为64,代表64个uniform变量
使用限制中的uniform变量数量时,170情况下会显现出较明显的卡顿,100~128之间会有一点卡顿,64左右较为正常。

电脑参数如下:
Windows版本:Windows 7 旗舰版
处理器:Inter(R) Core(TM) i5-4590 CPU @3.30GHz 3.30GHz
安装内存(RAM):8.00GB
系统类型:64位操作系统
显示适配器:Inter(R) HD Graphics 4600  /  Oray Display Mirror Driver
