了解關於什麼是 3D 或 3D 的一切

你想知道什麼是3D嗎？ 3D 或 3D 電影和圖像正變得越來越流行。由於我們處於現代時代，使用不同的工具製作 3D 電影很容易。但首先，我們需要了解所有關於 3D 的知識：背景、定義以及如何製作 3D 視頻。

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。什麼是 3D

3D 或 3D 對象顯示寬度、高度和深度。每天，我們都會看到 3D 物體，因為我們的物理環境本身就是 3D 的。由於我們人類具有3D感知，我們可以感知3D物體，也稱為深度感知。當你環顧四周時，我們眼睛中的視網膜形成了一個二維圖像，我們的大腦將這兩個圖像處理為 3D 視覺。但是你知道嗎？我們人類有用於深度感知的工具嗎？

以下是我們用於深度感知的人類工具：

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.

在我們的物理世界中也有不同類型的 3D。 3D 也被描述為一種圖像，可以產生不同距離的深度錯覺，通常用於計算機遊戲、圖形、虛擬現實和電影。

不同類型的 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 電影

既然您了解了 3D 的含義，請讓我們知道如何使用您可以使用的最出色的軟件應用程序播放 3D 電影。

藍光播放器是一個桌面應用程序，您可以在其中播放任何類型的視頻。使用此工具，您還可以在不使用任何插件的情況下播放 3D 電影。此外，許多人推薦這款媒體播放器，因為它的用戶界面簡潔乾淨。此外，這款強大的媒體播放器可以播放其他媒體播放器不支持的藍光光盤、藍光文件夾、DVD/文件夾/ISO 文件。您還可以欣賞 100% 無損音頻和震撼的高清環繞聲的高清視頻。更令人驚奇的是，您可以創建播放列表，這樣您就可以輕鬆地分離所需的視頻或音頻。

如何在藍光播放器中播放 3D 電影：

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。什麼是 3D 電視和 3D 眼鏡

有兩種類型的 3D 電視：主動快門式 3D、主動式 3D 和被動式 3D。這部分將區分它們的區別，並確定在觀看主動快門或被動 3D 電視時使用哪種類型的 3D 眼鏡。

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 與 3D

2D 和 3D 是計算機工作空間中的實際尺寸。二維或二維是使用水平和垂直維度（X 和 Y 軸）的平面對象。由於 2D 只有兩個維度，所以當您將它們轉到一邊時，您只會看到一條線。它只有高度和寬度，但沒有深度。而另一方面，3D 或三維包含高度、寬度和深度。三維圖像需要兩隻眼睛協同工作才能看到三維感知。如果 2D 使用 X 軸和 Y 軸，則 3D 會添加 Z 維度，以便您查看對象的深度。

如果你問哪個好用，2D 和 3D，答案都是。 2D 和 3D 有不同的優點和缺點。例如，您可以在任何設備上隨時隨地觀看 2D 視頻或電影，而無需佩戴任何特殊的 3D 眼鏡。但是，3D 電影產生的 3D 效果是驚人的，而且比 2D 更有趣。

第 5 部分。 如何將 2D 電影轉換為 3D
