From naked 3D to three-dimensional information architecture

About &http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Nintendo 3DS

February 25 this year Nintendo 3DS officially sold! This is all the small n party is an exciting news ~ believe that the speed of the students have started the new host bar @@!

The official opening of the 3DS, accompanied by the naked eye can directly watch the 3D effect of the technology of the public, so that we can discard 3D glasses. And Nintendo has created a new control called 3D Volume (3D Volume). The following is the Nintendo official website on the naked eye function of some explanations:

"NINTENDO3DS image is to use the principle of the left and right visual difference to generate three-dimensional." But viewing 3D images is a personal difference. For example, the left and right eye vision difference of the person (* 1), different people see the stereo image may have some difficulty, there may be a complete view of the stereo image. Nintendo 3DS to allow more customers to enjoy the joy of 3D video, the introduction of the 3D Volume control. 3D Volume slide down, the image of the three-dimensional will gradually weaken (* 2). Slide down to the bottom and see the full 2D image, which allows people who like to use 2D video to play games to enjoy the process.

* 1 for the use of glasses and other corrective vision of customers, wearing glasses to play games to more easily feel the icing on the cake.

* 21 part of the software, you can switch 3d 2d mode. ”

About stereo Images

Stereo image will give users a completely different use experience, it is not only a new sense, but also can carry more than the previous two-dimensional media more information, but also to the software business will bring many new creative points. Maybe most players have a vague idea of the technology, so first of all, I'm sure you'll have a superficial understanding of it after you finish this article ... (Although I don't know what Nintendo is doing.) Second, the new possibilities of three-dimensional images will be diffused.

In fact, before the naked eye 3D appeared, there are a variety of 3D products. For example, we have seen the three-dimensional painting as a child, there are now 3D movies and so on. But when looking at the east, we have to use a little bit of equipment (glasses) or some special training (eye, etc.). , otherwise it is absolutely not good ~ But why now can the naked eye.

As we all know, the creation of the three-dimensional sense and the parallax of the left-right eye has a great relationship.

So, above. I looked at the image of the left and right eye and measured it with a ruler. The largest ball in the picture, the left eye can see the content is about from F to i.9; the right eye can see the content from g.5 to I.6. So what we really see with the naked eye will be these things. However, purely graphic images are not able to express these, only to see the content from F.6 to J (middle picture).

Another example is the camera. There is a difference between the shutter and the frame, so there's always a subtle difference between the photos we actually get and the pictures we expect.

is actually carrying more information

The two eyes see something different. So we can not see the hidden things, the right eye on the right to see some of the time ~ so actually can see a little behind the things ~ like such a picture after the synthesis of a sense of proximity. That's why three-dimensional images can convey more information.

But as we usually touch the computer screen, it is actually a plane, although your content is so stereo, you can only take it flat on a plane to see. So it is absolutely impossible to see a bit of the blocked part, because this information in the flat image does not exist at all.

Open-hole synthesis

The main differences in 3D technology are actually synthesized above, that is, let the left and right eyes look at the different pictures respectively. The information on both maps is enough to generate a 3D image. ~ The brain is so effective and quick to synthesize two different images together and produce three-dimensional. It's just that we don't realize it under normal circumstances. Now, the process must be simulated manually.

1. Three-dimensional drawings of the way is the head-up or the method of the process. This method is relatively blunt and simple, but it is best to achieve.

2. Rely on a variety of principles of the filter, so that the left eye only see the left, the right eye only see the right picture (3D film). The method of filtering red and green light will produce chromatic aberration, but the method of polarizing is very good to solve the problem of chromatic aberration.

3. With a special screen, this screen allows you to look from left to right and from right to left to see things different. This is a bit like when we were a child bought a card, from this point of view is the Monkey King, turning the card into a pig ... Maybe the naked 3D uses a screen of a similar nature.

It can be seen that the naked eye actually just changed a new way to solve the problem of image synthesis.

For continuous animation, the easiest way to do this is to tie two cameras together to simulate a person's two eyes.

Three-dimensional information architecture

With the addition of 3D elements, the information architecture of digital media may change greatly. For example, an application like a browser, the address bar and various other functions of the control in a certain layout to arrange the example to a screen. So the question is, how to arrange these controls is more reasonable and efficient. Because the area of the computer screen is limited, to increase the size of the control area is bound to reduce the size of the page, so it will appear like the chrome design, a very important goal is to show as much of the content of the page as possible rather than the browser itself.

But in the 3D world, the problem has suddenly become less obvious. The reason is that the information of 3D space is no longer only can expand to the top and bottom of the tile, but also can be vertical depth. Controls no longer occupy a site with the page content, and they are distributed across different layers. Even the content of the Web page itself can be distributed across different layers. So maybe even web design is very different from the present. In this way, all of our layout and interactions will be different. The space for creativity is also getting bigger. Of course, the current application of 3D technology is still the electronic entertainment field, where the expansion of novel entertainment is essential. Nintendo as an established company, has always been very important game and creativity, here I wish they sell ~
