css3加js做一个简单的3D行星运转效果

前几天在园子里看到一篇关于CSS3D行星运转的文章,原文在这里,感觉这个效果也太酷炫了,于是自己也就心血来潮的来尝试的做了一下.因为懒得去用什么插件了,于是就原生的JS写,效果有点粗超,还有一些地方处理的不是很好,如果有好的建议万望留言告知,不胜感谢.源代码已上传到github上,点这里获取.好了不说废话了,下面附上代码. HTML部分 <div class="path-Saturn"> <div id="Saturn" title="土

Three.js学习笔记 – “我和小伙伴都惊呆了”的特效和Three.js初探

什么是Three.js three.js是JavaScript编写的WebGL第三方库.提供了非常多的3D显示功能.Three.js 是一款运行在浏览器中的 3D 引擎,你可以用它创建各种三维场景,包括了摄影机.光影.材质等各种对象.你可以在它的主页上看到许多精采的演示.不过,这款引擎目前还处在比较不成熟的开发阶段,其不够丰富的 API 以及匮乏的文档增加了初学者的学习难度(尤其是文档的匮乏)three.js的代码托管在github上面. 上面摘自百度百科.依我来看就是一个在HTML5画布(ca

Web纯前端“旭日图”实现元素周期表

一.什么是旭日图 旭日图是在Excel 2016中新增的一种图表.有些类似饼图,饼图的优势是可以显示占比.但是饼图只能显示单级数据.旭日图用来表示多层级数据的占比.旭日图以一种分层方式显示,非常适合用来显示层级数据.层次结构中每个级别的比例通过1个圆环表示,离原点越近代表圆环级别越高,最内层的圆表示顶级结构,然后一层一层去看数据的占比情况. 我们通过一个简单的示例,初步感受一下旭日图的魅力. 季度 月份 周 销量 Q1 1月份 29 2月份 第一周 63 第二周 54 第三周 91 第四周 78

利用CSS3D效果制作简易旋转木马效果

最近看一下css3d的一些特性,想着也实验学习一下,制作个小demo之类的.就练习了一下.开发一个粗糙的选择木马效果,如图 其实就是找到角度和位置,计算每根柱子的旋转角度摆放到3d空间的置顶位置即可.然后利用css的animate属性让3d舞台无线旋转,就有了一简易的旋转木马效果.感兴趣的可以看一下,可以把代码中的图片路径改为自己的图片地址就行了.直接可用. 代码如下: <!DOCTYPE html> <html> <head lang="en">

js跨域

第一次写博客,好紧张,不知道能写成啥样,哈哈哈. 自己的一知片解,有错请多多指教,嘻嘻嘻. 一.何为跨域? 只要协议.域名.端口后任何一个不同,就是跨域. 举个例子: http://www.example.com 协议不同 https://www.example.com http://www.example.com 域名不同 http://www.test.com http://www.example.com 端口不同 http://www.example.com:81 注意:ip相同,域名不同
