1)在上一篇貼文裡,我介紹了 #tezos 以及 #genart 的獨特性,而在這一篇貼文中,則是要有系統的教會大家,如何欣賞生成式藝術。時間回到1896年,當觀眾首次看到盧米埃爾兄弟的『火車進站』電影時,他們嚇得驚慌失措而逃離,而這正呈現新媒體的特質,人們必須習慣新的敘事方法後,才能開始理解其內涵。
2)生成式藝術在區塊鏈的推波助瀾下,跟過往的(2021年前)的型態很不同。早些年前,生成藝術因其可複製性,我們在創作時較重視表演性, audio/visual 的形式,是市場主流;嚴格的控制frameRate、與其他媒材的協調性(聲音、光線),然而當區塊鏈讓生成藝術固定型態後,一切的發展又都不同了。 https://vimeo.com/133222869
3)現今的生成藝術追求的是:
a.演算法美學(perlin noise、cellular、fractal..
b.自訂系統的個人宇宙
c.迷因文化擴張(pepe、pixel art、ape..
d.當代繪畫性的延伸

演算法是生成藝術的基底,就像是繪畫中我們會使用縫合法、渲染法、重疊法等,如果你能夠看懂其中奧秘,發現藍籌就不會是碰運氣 https://www.notion.so/That-Creative-Code-Page-c5550ef2f75741
a)以下介紹幾件經典的作品,以及其演算法
首先是 #fxhash 的genesis代表RGB by @ciphrd
rgb 使用的演算法是細胞自動機,由數學家馮·諾依曼為了模擬生物細胞的自我複製而提出的,並經由康威的生命遊戲等應用,逐漸被世人所熟知。

簡單的規則,卻可以製造有機的結構,成為fx上最經典的作品。 https://www.fxhash.xyz/generative/slug/rgb-elementary-cellul
a.2) Perlin noise 、flow field, 流場演算法。
流場演算法是最被人知曉的算法,原因來自於AB #fidenza by @tylerxhobbs 取得的巨大成功。

該算法能夠製造平滑的亂數分佈,並可以運用在2維或3維的座標系統裡,因此特性易於模擬流體、甚至自然植物的生長狀態。

#TurnerLight 也混合此算法以及FBM https://www.fxhash.xyz/generative/slug/turner-light
a.3)L-system(簡稱LS),也是模擬植物生長的常用的算式。
在fxhash上面有許多模擬自然的佳作,包含Garden, Monoliths by @zancan 、Mediterranean by @kira0art
、Deep Forest by @nudoru 、Rudeneja by @rhaegar_art

LS搭配遞迴可以產生許多有趣變形,它也成為結構化造型必備的算式。 https://www.fxhash.xyz/generative/19642
a.4) 遞迴算式也就是差分方程式,透過一次次的迭代,子繼承父,能表現出非常複雜的結構;許多生成藝術家都透過遞迴來製造,無止境可以被探索的世界。

碎形也是其主要運用,常見於自然結構的模擬上。

Microgravity by @iRyanBell 、Mandaloids by @jamportz 、Chrysalis by @arsiliath &
@_monotau https://www.fxhash.xyz/generative/11248
a.5)packing 常用來產生亂數的位置,可以有效的避免物件重疊,透過距離偵測碰撞,可以產生留白的間隔。
當然你也可以透過更進階的quadtree算法來偵測,讓運算效能更好。

你可以見到 Maplands by @amygoodchild 、Sierras by @_NatSarkissian、Automatism by @Yazid,都使用這方法。 https://www.fxhash.xyz/generative/5713
a.6)另外使用particle system以及Reaction–diffusion ,也能產生類細胞的組織以及運動狀態,藝術家常用此方法來模擬黏菌 Slime mold (physarum)。
你可以見到 stigmergy by @gengrdn、Primordium by @mxsage、Ethereal Microcosm by @ciphrd 都使用類似方法。 https://www.fxhash.xyz/generative/12345

1)When I was younger and working at museums, some of the indigenous art I saw had a great influence on me. The vibrant lines, bold color choices, and respect for nature left a deep impression on me.
I especially appreciate artists like Max LIU, whose works fully express the thoughts and compassion of humans towards all things.

In terms of the expressionist use of color and lines, I am deeply influenced by Paul Klee, and this often becomes a recurring subject of contemplation in my programming creations.

If one day both #tezos and #eth cryptocurrencies suffer a flash crash and their values return to zero, would NFTs still have value on these chains?
My guess is: 1. Trading on the market will come to a complete halt in the short term and many NFTs will truly die.
2.However, as the market panic subsides (which may take some time), NFTs on the chain will survive in some other form, possibly through other means of changing the way transactions are made, or by re-establishing the value of the chain.
