Google Launches Virtual World Called 'Lively'

2008-07-09
[Source:Unkonwn ]



  Google (NSDQ: GOOG) on Tuesday launched a Web-based virtual world called Lively as a way to make the social Web more dynamic.

  "The Lively team wants to help people experience another dimension of the Web," said Google engineering manager Niniane Wang in a blog post. "We hope you will use the product to express yourself with and without words, and to do this in the places you already visit on the Web."

  Lively feels more like a Google Talk-powered chat room with 3-D camera controls than an immersive environment like Second Life. In part that's a function of the small in-browser window that presents Lively's various rooms -- full screen graphics are inevitably more compelling.

  And in part that's a function of performance. It's likely that the user experience is better with a better computer. The IBM (NYSE: IBM) ThinkPad T2500 (2GHz Core Duo) I used to visit Lively for the first time responded too slowly for the experience to be enjoyable. (Eerily, though Lively crashed Firefox 3, requiring that I restart my browser, sounds from the Lively world continued uninterrupted, even though I didn't try to log in again. As I write, there's intermittent canned laughter bubbling from my speakers.)

  Entering the Lively environment requires Windows XP or Vista, Microsoft (NSDQ: MSFT) Internet Explorer or Firefox, and the Lively browser plug-in. Mac support may be a long time coming. A Google help document says that Lively is a Google Labs project that's still being tested. "We hope to support other platforms in the future, but for now you'll need a Windows system to access Lively," the help document says.

  Lively rooms, created by users or already constructed, can be embedded in any Web site. Visitors to Lively can enter the various rooms to chat. They can also modify the appearance of their Lively Avatar and can add furniture to rooms.

  Lively rooms can display YouTube videos on virtual TVs and display Picasa photos in virtual picture frames. They can also display Google Desktop gadgets and play music uploaded from the user's computer -- insert your copyright lawsuit here.

  Google says in its help documentation that it is working with a small number of trusted testers, vendors and creative agencies on special items for Lively. The company says that it expects to enable more user content generation soon. At some point, there will almost certainly be virtual commerce and advertising.

  Lively is certainly easier to use than Second Life, but it lacks the latter's programmability. For Google developers and content partners that may not be an issue -- the inaccessibility of the Lively's code infrastructure won't matter much if Lively generates lots of gadget use and ad page views.

  If you like chatting and emoting online via a 3-D avatar, Lively looks like a winner. And if that sounds fatuous, you may be happier with Age of Conan, EVE Online, Shadowbane, or World of Warcraft.

基于flash的3D引擎: Alternativa3D

2008-05-11
[Original: istar]

  Alternativa3D 是由 Altenativa Game发布的一款由ActionScript3.0编写的Flash 3D引擎。近日,引擎的开发团队在blog中声称将在5月底把 SWC-library 开源,并且将为商业用途提供许可。下面是官方的几个demo:

1.3D互动人物头像

2.仿Quake的demo

3.XX神庙场景

以下是自己对该技术的一些思考:

*浏览插件的不统一,阻碍了WebVR的发展以及应用普及

大多数VR的浏览都需要一个插件, 使得用户感觉非常不方便。就拿VRML来说,一些VRML文件在这个浏览器中显示正常,但在另一个浏览器中看就会缺少东西或者报错无法显示, 对浏览器的兼容性不好。

这种基于flash的Web3D方案,确实可以很好地解决上面的问题。由于视频网站的推动,现在大多 数上网的用户也都会安装flash player插件,所以基于flash的webVR大有发展前景。

* 应用领域的相关思考

alternativa的blog上提到了该技术的应用领域:第一(三)人称的3D游戏、建筑效果模拟、多用户娱乐 媒体、促销网站、广告(包括"3D-banners")、科学和教育互动项目。

而结合网上的资料,我认为基于flash的Web3D在以下领域的应用至少在近1、2年内是不太现实的:

渲染效果和网络速度的限制,在1(3)人称3D游戏上的应用就很有限--游戏的流畅性很重要;
显示效果的局限性,也同样限制了该技术用于建筑效果模拟中--建筑效果对真实度要求较高;
现在的2Dflash用于科学和教育的案例就比较少,3Dflash也应该不会有太多应用,应用也主要只在集中在线互动教学上。

该技术大de应用潜力:

3D flash小游戏,把一些2dflash小游戏搬到3d空间中,趣味性会更强;
网上商店的虚拟展示,简捷的3D商品实体远远胜过无数的文字描述和图片介绍;
广告,广告从来就是从吸引人的注意力开始的,全新的Web3D广告形式也一定能起到较好的广告效果;
普通网站的3D互动元素,任何一个网站都可以在恰当的地方引入Web3D元素,使网站的展现方式从杂糅文字与图片的平板效果中解放出来,全面提升网站的观赏性和实用性。

其它领域的应用现在我还没想到,但是随着计算机技术的发展,web3D一定会有更多的应用。

* Alternativa3D的优缺点

优点:插件统一,浏览方便,渲染效果硬件无关,通用性,很好的技术开发团队。

缺点:由于应用于web上,对传输速度的考虑,限制了文件的大小和精细度,从而限制了应用的领域。
