3D 网站和应用程序
在过去的几年里，我一直在努力理解为什么互联网上真正有用的 3D Web 应用程序如此之少。 现在是 2009 年了，一切看起来仍然像西尔斯目录中的页面。 每天晚上你打开电视就能看到飞行的标志。 之后，您可以怀旧并打开 ol' N-64 并玩一些塞尔达或马里奥赛车。 在 PC 上，《模拟人生 2》已经推出快 6 岁了。然后还有《魔兽世界》。 当前这一代用户（比如说 Facebook 人群）在处理多维环境方面没有任何问题。
然而，网络上似乎没有发生任何真正身临其境的事情。 我听说 VRML 和 X3D 至少有 10 年了，而且……噗……——没有发生什么惊天动地的事情。 Java 3D ？ .. 凉爽的 ！ ..但是......仍然......等待和等待。
您认为人们是否需要一款杀手级网络应用程序才能习惯或寻求使用更具吸引力的网络体验？
我不是在谈论《第二人生》和其他专用下载应用程序。 我可能更关注 Lively、SceneCaster、Hangout 或其他六种可以“轻松”直接交付到网页的应用程序。
我自己特别感兴趣的是虚拟商店和沉浸式购物领域。 试图理解为什么普通用户不愿意浏览和漫步不断变化的购物中心空间（就像在现实世界中一样）并享受意外的发现是一个挑战。
3D网络总是在未来5年吗？
I have for the last several years been struggling to understand why the Internet has so few actually useful 3D web applications. It's 2009 and still everything looks like pages from a Sears catalog. You can turn on your TV and find flying logos every night. After that you can get nostalgic and flip on ol' N-64 and play some Zelda or Mario Kart. On the PC, Sims 2 is approaching 6 years old already.. And then there's WoW. Current generation of users - the Facebook crowd, let's say - has ~no~ problem dealing with multi-dimensional environments..
And yet, nothing really immersive seems to happen on the web. I've been hearing about VRML and X3D for at least 10 years and ... pffft .. - nothing earth shaking going on there. Java 3D ? .. cool ! .. but ...... Still .... waiting and waiting.
Do you think it will take a killer-web app before people become accustomed-to or will seek to use what could more more engaging web experiences?
I am not talking about Second Life and other dedicated downloaded applications. I probably am more focused on apps like Lively or SceneCaster or Hangout or a half dozen others that are delivered 'painlessly' directly into web pages.
My own particular interest is in the domain of virtual stores and immersive shopping. Its been a challenge trying to understand why an average user would not want to browse and wander a changing mall-space - like in the real world -- entertained by unexpected discovery.
Is the 3D web always going to be 5 years in the future ?

3D商店似乎将现实世界购物中心的缺点带到了互联网上。 人们真的想“步行”通过亚马逊来找到他们想要的东西吗？
滚动浏览页面上的搜索结果列表比浏览三维空间来查看相同的结果要快得多。
先前评论中给出的链接（http://www.windowshop.com/）很好地说明了这一点（尽管它基本上是一个带有缩放功能的 2D 界面）。
3D 在查看单个项目时占有一席之地。 一些网站已经推出了其商品的“全景视图”。 这似乎为客户增加了价值，这就是这样做的原因。
不过，我不太确定 3D 对于导航来说是否是一个好主意。
3D shops seem to bring the disadvantages of real world malls to the Internet. Do people really want to "walk" through Amazon to find what they're looking for?
It's much faster to scroll through a list of search results on a page than to navigate through a three dimensional space to look at the same results.
The link given in a previous comment (http://www.windowshop.com/) illustrates that quite well (even though it's basically a 2D interface with zooming).
3D has its place when it comes to looking at individual items. Several sites already feature "surround views" of their goods. This seems to add value for the customers, which is why it is being done.
I'm not so sure whether 3D is such a good idea for navigation, though.
W3C 和 Web3D 联盟之间正在进行关于将 X3D 集成到 HTML5 的讨论（就像 SVG 为 HTML4 所做的那样）。
初步项目：http://www.x3dom.org/。 自去年以来，该项目非常活跃。
阅读这里的论文，这很有趣。 鉴于 W3C 似乎密切关注该项目，并且计划使用多个渲染后端（实际上是 WebGL，但后来是 Google O3D），也许 VRML/X3D 人员的旧梦想可能在不久的将来成为现实。
然而，由于这取决于 HTML5 的采用，我认为至少 5 年......
There is an ongoing discussion between the W3C and the Web3D consortium about integrating X3D to HTML5 (much like SVG is done for HTML4).
A preliminary project: http://www.x3dom.org/. The project is really active since the last year.
Read the paper here, it is quite intersting. Given that the W3C seems to follow closely that project, and that several render backends are planned to be used (actually WebGL, but later Google O3D for example) maybe the old dream of VRML/X3D guys could become reality in a not so distant future.
However, since it depends on HTML5 adoption, I think 5 years to be a minimum...
创建基于 Web 的 3D UI 技术的一些主要问题：
我认为在谷歌之前您不会看到亚马逊或 eBay 推出 3D 界面有一种索引它们的方法。
Some of the major problems with technologies that would create web based 3d Uis:
I don't think you will see a push from amazon or ebay to roll out a 3d interface until google has a way of indexing them.
因为使用 3d 并不是传达信息列表和表格数据的有效方法。 这包括销售产品的电子商务网站。
我不想必须旋转 3D 摄像机角度、向前移动并最终左转才能到达 Amazon.com 销售花园软管的部分。 我只想输入“花园软管”，然后在搜索结果中查看易于理解的产品列表。
Because using 3d isn't an efficient means of conveying lists of information and tabular data. This includes e-commerce websites selling products.
I don't want to have to rotate a 3d camera angle, move forward and finally turn left to arrive at the section of Amazon.com selling garden hoses. I just want to type in "Garden Hoses" and look at my easy to digest list of products in my search results.
您必须等到所有浏览器（至少是主要的浏览器）都内置 3D 支持，就像 3D 图像支持一样，才能真正普及。 这需要一种或两种格式才能“获胜”，就像 gif 和 jpg 赢得图像竞赛一样。 我们可能会通过 Silverlight 和 Adobe Air 实现这一目标。
“普通”人不想安装插件和扩展 - 他们甚至可能不知道如何安装。 我们极客和书呆子总是会安装最新的小玩意，但我们只是普通大众的一小部分。
编辑：我刚刚意识到已经有一个大多数人都会安装的插件 - 它叫做 Flash。 真正的障碍是没有明显的需求。
编辑： Mozilla 和 OpenGL 结合在一起 - 这可能是 3D 需要起飞的，但我们必须拭目以待。
You'll have to wait until 3D support is built into all browsers (well the major ones anyway) in the same way that 3D image support is before it really takes off. This will require one or two formats to "win" in the same way that gif and jpg won the image race. We might get there with Silverlight and Adobe Air.
"Regular" people don't want to install plugins and extensions - they may not even know how to. We geeks and nerds will always install the latest gizmo, but we're a small section of the general populace.
EDIT: I've just realised that there is already a plugin out there that most people will have installed - it's called Flash. The real blockage is that there's no perceived need.
EDIT: Mozilla and OpenGL get together - this might be what 3D needs to take off, but we'll have to wait and see.
