了解关于什么是 3D 或 3D 的一切

你想知道什么是3D吗？ 3D 或 3D 电影和图像正变得越来越流行。由于我们处于现代时代，使用不同的工具制作 3D 电影很容易。但首先，我们需要了解所有关于 3D 的知识：背景、定义以及如何制作 3D 视频。

In this article, we will dig into 3D and its parameters. So, if you want to learn about what is 3D, read this article.

第 1 部分。什么是 3D

3D 或 3D 对象显示宽度、高度和深度。每天，我们都会看到 3D 物体，因为我们的物理环境本身就是 3D 的。由于我们人类具有3D感知，我们可以感知3D物体，也称为深度感知。当你环顾四周时，我们眼睛中的视网膜形成了一个二维图像，我们的大脑将这两个图像处理为 3D 视觉。但是你知道吗？我们人类有用于深度感知的工具吗？

以下是我们用于深度感知的人类工具：

Stereoscopic vision - Stereoscopic vision is a sense of depth perceived by the two eyes. It is one of the abilities of the brain to register 3D shapes and visuals. In this vision, the objects look separated when closer than distant ones.

Parallax - The angles between two lines measure this type of vision. When you move your head side by side, closer objects move more than distant objects.

Size Familiarity - If you are familiar with the size of an object, even though it is far, you can approximately know how big it is to appear in size. In the same way, if two objects have the same size but the other one is bigger, it is assumed that the larger one is closer.

Accommodation - When you focus on a close object, your eye’s lenses physically change. In that way, you will know how far the object is. Also, it is the way of the eye to keep the focus on an object.

Aerial Perspective - In aerial perspective, you will see objects smaller because the view is far. Distant objects also appear to have less contrast and color saturation.

在我们的物理世界中也有不同类型的 3D。 3D 也被描述为一种图像，可以产生不同距离的深度错觉，通常用于计算机游戏、图形、虚拟现实和电影。

不同类型的 3D：

3D Computer Graphics - 3D computer graphics can generate 3D objects in a display screen or two-dimensional space. The pixels in 2D graphics have different properties, such as position, color, and brightness. The 3D pixels then lie on a Z-axis. When the pixels are combined with their depth, it will result in a 3D surface, also called a texture.

3D Films - 3D films are motion pictures that have 3D depth on them. With the help of 3D glasses, we can watch a 3D film. To make this kind of film, creators use stereoscopic vision, which means two images are shown simultaneously, each for one eye.

3D Printing - 3D printing is also known as additive manufacturing. It is a process of making a 3D in solid form from a digital file. Using a Computer Aided Design (CAD), you can print a 3D object from a digital model.

第 2 部分。 如何播放 3D 电影

既然您了解了 3D 的含义，请让我们知道如何使用您可以使用的最出色的软件应用程序播放 3D 电影。

蓝光播放器是一个桌面应用程序，您可以在其中播放任何类型的视频。使用此工具，您还可以在不使用任何插件的情况下播放 3D 电影。此外，许多人推荐这款媒体播放器，因为它的用户界面简洁干净。此外，这款强大的媒体播放器可以播放其他媒体播放器不支持的蓝光光盘、蓝光文件夹、DVD/文件夹/ISO 文件。您还可以欣赏 100% 无损音频和震撼的高清环绕声的高清视频。更令人惊奇的是，您可以创建播放列表，这样您就可以轻松地分离所需的视频或音频。

如何在蓝光播放器中播放 3D 电影：

Step 1. Download Blu-ray Player on your device. Follow the installation process, then run the app.

Step 2. On the software’s main interface, click the Open File button. Your device’s files will appear, where you will select your 3D movie.

Step 3. Then, your video will begin to upload. You can now wear your special 3D glasses and enjoy watching your 3D movie.

第 3 部分。什么是 3D 电视和 3D 眼镜

有两种类型的 3D 电视：主动快门式 3D、主动式 3D 和被动式 3D。这部分将区分它们的区别，并确定在观看主动快门或被动 3D 电视时使用哪种类型的 3D 眼镜。

Active-shutter or Active 3D is a type of 3D TV that displays high-quality 3D images alternately on the screen. Active 3D TV displays alternate images on the screen for the right and left eyes. The 3D glasses then shutter black alternately to portray the 3D effect seen on your TV screen. This causes each eye to see the image made for them. The 3D glasses you must use when watching in an Active-shutter 3D are 3D active glasses. This type of 3D glass needs a battery that it uses to block and shutter the lenses on the glasses electronically. These glasses are incorporated with LCD lenses to coordinate with alternating frames.

In contrast, Passive 3D TV is somehow similar to the 3D technology that movie theaters use. This type of 3D TV uses special filters on the screen to see 3D using polarized lenses in the glasses. Furthermore, Passive 3D TVs blend the two frames in one, alternately between the horizontal lines for the left eye and right eye. The glasses that these 3D TVs use are Passive 3D glasses which contain different polarization on each lens. The other eye only sees the odd lines, while the other sees the even lines to produce a 3D image. The Passive 3D glasses do not require batteries to work.

第 4 部分。2D 与 3D

2D 和 3D 是计算机工作空间中的实际尺寸。二维或二维是使用水平和垂直维度（X 和 Y 轴）的平面对象。由于 2D 只有两个维度，所以当您将它们转到一边时，您只会看到一条线。它只有高度和宽度，但没有深度。而另一方面，3D 或三维包含高度、宽度和深度。三维图像需要两只眼睛协同工作才能看到三维感知。如果 2D 使用 X 轴和 Y 轴，则 3D 会添加 Z 维度，以便您查看对象的深度。

如果你问哪个好用，2D 和 3D，答案都是。 2D 和 3D 有不同的优点和缺点。例如，您可以在任何设备上随时随地观看 2D 视频或电影，而无需佩戴任何特殊的 3D 眼镜。但是，3D 电影产生的 3D 效果是惊人的，而且比 2D 更有趣。
