什麼是NFT？What's NFT?
NFT 指「非同質化代幣」，為英文Non-Fungible Token的簡稱。NFT是一種被稱為「區塊鏈」數碼帳本上的數據單位，有別於一般同質化的「加密貨幣」，由於相片、影片、聲音等形式的作品具創意獨特性，NFT被稱為「非同質化」。
因代幣可於區塊鏈上被完整追蹤，其不能互換的特性常令人視NFT作虛擬資產，並由其擁有者於NFT平台轉發或發售所有權證明。
NFT stands for non-fungible tokens. They are special digital assets that consist of digital data recorded in a blockchain. Because NFTs are uniquely identifiable, they differ from cryptocurrencies, which are fungible. NFTs typically contain references to digital files such as photos, videos, and audio.
Since blockchain is traceable and unalterable, some people deem NFTs as virtual assets whose ownership can be transferred, sold and traded by the owners, creating market values associated with the digital files they reference.
設計NFT的第一步 Where to start?
NFT 沒有特定的藝術規範。縱使藝術業界對NFT的興起持有不同意見，近年世界各地的博物館、畫廊及拍畫行都紛紛開設平台專門推廣、展示、甚至銷售NFT，令NFT越見普及化。
我們鼓勵學生根據自己的興趣自由創作，或根據作品的意念及發佈平台的要求預先進行資料搜集及規劃。事實上，NFT的藝術創作形式非常多元化，像素畫、3D模型、音樂影片、甚至數碼自拍圖像等都是常見的NFT作品。本文章將主要詳述衍生藝術的基礎創作方法。
There is no rule on the style of NFT. Although there is heated industry discussion over the surge of NFT, more and more museums, galleries and auction brokers are setting up new platforms specialised in promoting, displaying or even trading NFTs, making NFTs more accessible to the general public globally than ever before.
We recommend students to choose whatever styles they like to start their creation. By planning ahead and identifying why and where you would like your work to be published, students can narrow down options and pick the right style. Indeed, NFT art is very dynamic that it can be pixel art, 3D models file, music video or even selfies and more! In this article, In this article, we will focus talking about generative art, one of the most popular system of NFT art creation.
什麼是衍生藝術 ? What's generative art?
衍生藝術，又稱為演算法藝術或生成藝術，是指結合電腦程式運算的藝術創作形式。由程式開始運算至結束，創作過程並不涉及人為成份，故衍生藝術作品含有部分或全部非人為的特性。
Bored Apes 及 CryptoPunks系列是世界知名的衍生藝術NFT藏品之一。
Generative art, also known as algorithmic art and synthetic media, refers to art that has wholly or partially been created with the use of an autonomous system, meaning that the artwork consists of features that are non-humanly be determined. Bored Apes and CryptoPunks are some world-famous examples of NFT collections developed based on such a system.
學習利用程式創作NFT！ Design your own generative NFT!
假設你的創作目的為2D頭像設計，而你將會利用坊間入門的電腦程式作生成器。生成器將會以把不同組件以不同組合方式來建立各種圖像。所以你需要先構想你的頭像將包含什麼組件：
組件的數目
組件的種類（如：主體、配件、背景）
組件的變化程度（如：顏色、形狀）
Assuming that you plan to create artwork of 2D profile images and you will be using a generator which can be easily found online. Since the generator will assemble different attributes in different combinations to generate a collection of artwork, you will first need to create a selection of attributes by determining
No. of attributes
Nature of each attribute (e.g. body, accessory, background)
Variations of each attribute (e.g. color, shape)
下一步，你需要製作各種組件的設計原檔。創建組件文件夾（如：電車車身）。於文件夾內複製原檔，為各組件加入微妙變化，再另存作新檔（如：電車車身_綠色、電車車身_紅色）。請緊記有系統地組織及命名檔案，令生成器能夠正確地將對應組件及把它們組合起來。
Next, create a design master file for each attribute. Create a folder (e.g. tram body) for each attribute. Then, make multiple copies of each attribute and apply variations to further save them as new files (e.g. tram body_green, tram body_red). Remember to arrange and rename files in a systematic way so that the generator can correctly put them back in your desired order.
4個必讀設計Tips！4 Tips you must know!
確保同類組件的檔案大小一樣
確保所有組件擁有透明背景，並儲存作PNG
正確地排序組件文件夾
決定各組件的稀有度
設計師都在用什麼軟件？ What tools do creators usually use?
有適合學生使用的設計軟件嗎？ I'm a student, are there any free resources for creating digital art?
有！網上有不少免費又適合初學者使用的設計軟件。話些軟件功能齊全，而且容易上手。Jessica特別推介以下2個平台，並且提醒各位同學，你的創作意念比起用什麼軟件繪圖重要得多！
Yes, there're a number of free tools with comprehensive design functions. Indeed, some of them may even be more user-friendly for beginners! Remember, your ideas are always more important than the softwares you use!
