Blender is a free and open-source 3D computer graphics software toolset used for creating animated films, visual effects, art, 3D printed models, motion graphics, interactive 3D applications, and computer games. Blender's features include 3D modeling, UV unwrapping, texturing, raster graphics editing, rigging and skinning, fluid and smoke simulation, particle simulation, soft body simulation, sculpting, animating, match moving, rendering, motion graphics, video editing, and compositing.

A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques.

OpenCV is a library of programming functions mainly aimed at real-time computer vision. Originally developed by Intel, it was later supported by Willow Garage then Itseez. The library is cross-platform and free for use under the open-source BSD license.

The Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations and narrative text. Uses include data cleaning and transformation, numerical simulation, statistical modeling, data visualization, machine learning, and much more.

In software engineering, a software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code.

In computer science, a sorting algorithm is an algorithm that puts elements of a list in a certain order. The most frequently used orders are numerical order and lexicographical order. Efficient sorting is important for optimizing the efficiency of other algorithms that require input data to be in sorted lists.

pointers 和 arrays 對於某些低階任務可能有存在的必要，但我們應該盡量避免使用它們，因為他們容易出錯又很難除錯。一般而言應該優先使用程式庫提供的抽象事物而非語言內建的 array 和 pointer，這一忠告在「多用strings，少用C-Style 字串（亦即以null結尾之字元array）」這件事上尤其合適。

C++中的 struct 和 class 基本是通用的，使用 class 時，類中的成員默認都是 private 屬性的；而使用 struct 時，結構體中的成員默認都是 public 屬性的。class 繼承默認是 private 繼承，而 struct 繼承默認是 public 繼承。class 可以使用Template(模板)，而 struct 不能。

我們不能從該Class的外部access該Class的private members。但是，如果將non member function聲明為class的`friend`，我們就可以使其access該class的private member。 這是通過在Class中包含此外部function的聲明並在其前面加上關鍵字`friend`來實現的。C++中的每個Object都可以通過稱為`this` pointer來訪問其自己的address(地址)。在member function中，`this`指 refer to the invoking object。
