By Daniel Du After a long time waiting, IE11 finally supports WebGL, which enables us viewing our 3D/2D models on Internet Explorer with view and data API if IE is your favorite browser or your only option for whatever reason. Here are some tips to m…
大家经常会问到,使用View and Data API怎么做界面的本地化,来显示中文,现在好消息来了,从v1.2.19起,View and Data API开始支持多国语言界面了.你需要制定版本号为v1.2.19. 其实,总是推荐大家在引用viewer的Javascript类库时要指定版本号,因为View and Data API一直在快速演进中,有些API难免会有变化,为了防止你的Web应用受被变化的API影响,建议你加上版本号,并且及时关注view and data API的最新进展情况,及…
什么是View and Data API? 使用View and Data API,你可以轻松的在网页上显示大型三维模型或者二维图纸而不需要安装任何插件.通过View and Data API,你可以对模型进行视点控制.选择控制.属性信息查询等等,而且还可以把这样无插件的模型浏览器和您自己的其他信息系统集成起来. 一些PPT: 基于Web的智能建筑BIM运维方案 View and Data API 分为两部分: REST API - 用于模型的上传和转换 Client JavaScript AP…
By Daniel Du I have been studying Meteor these days, and find that Meteor is really a mind-blowing framework, I can talk about this latter. I was inspired by this question on forum and started to looking at the possibilities of using View and Data AP…
By Daniel Du When working with View and Data API, you probably want to contain viewer into a <div> tag, the position and size of <div> can be defined with CSS. The HTML can be simple as below, a <div> tag as a container, the position and…
By Daniel Du With View and Data API, you can hide some elements in viewer by calling "viewer.hide(dbIds)", when the elements are hided, it actually make it transparent with a shallow mark to it, or make it ghosted. It is a nice feature as user p…
大家使用View and Data API做三维模型开发,必然首先要理解View and Data API的坐标系统,即XYZ三个轴向分别是怎么定义的.Three.js里面提供了一个AxisHelper,但如果你直接运用的话,你会发现在viewer中并不显示,并且控制台中会有这样的错误信息:"Only THREE.Mesh can be rendered by the Firefly renderer. Use THREE.Mesh to draw lines." 原因是因为View…
大家在使用View and Data API开发过程中,经常会用到的就是改变某些元素的颜色已区别显示.比如根据某些属性做不同颜色的专题显示,或者用不同颜色表示施工进度,或者只是简单的以颜色变化来提醒用户以示区别.作为开发者,一定会喜欢看的这样的API: //load the extension viewer.loadExtension('Autodesk.ADN.Viewing.Extension.Color'); // an array of node Id var elementIds= […
对于云API服务,常见的方式就是按照API调用次数收费,某些API调用也就有某些限制,比如在特定时间内只允许调用指定的次数以免造成滥用.虽然Autodesk的view and Data API目前还没有应用这样的限制,但我们最好也能实现这样的机制,比如对于或者Access Token这样的操作,一个Access Token是有一定的有效期的,在这个token的有效期内,我们就没必要重复发出API调用获取新的Acces Token,只有返回仍然有效的token就可以了.下面是c#实现的简单的逻辑,…
