展開 生成極小曲面的主要方法在下文都將簡(jiǎn)單介紹,也歡迎大佬指導(dǎo)
1、對(duì)于新手來說極小曲面建模其實(shí)是一個(gè)復(fù)雜的過程，但是現(xiàn)在存在兩個(gè)基于MATLAB的極小曲面建模插件可以幫新手快速建模
插件是基于MATLAB的，所以第一件事應(yīng)該是在電腦上裝MATLAB軟件
第一個(gè)軟件
FLatt Pack: a research-focussed lattice design program
DOI: 10.1016/j.addma.2021.102510（自己下載論文，看完論文然后按論文指導(dǎo)操作就行）
沒有裝MATLAB會(huì)閃退
軟件操作界面
第二個(gè)軟件
MSLattice: A free software for generating uniform and graded lattices based on triply periodic minimal surfaces
DOI: 10.1002/mdp2.205
主要優(yōu)勢(shì)是梯度結(jié)構(gòu)，自由性比較大
軟件操作頁面
3、用犀牛Rhino中的Grasshopper來進(jìn)行建模，這是我最開始的方法，但是當(dāng)時(shí)網(wǎng)上教程不全我就放棄了，有興趣的可以看知乎的一篇文章

這里面詳細(xì)介紹了極小曲面的建模過程，但是你用過以后就會(huì)發(fā)現(xiàn)還是比較復(fù)雜的；
4、接下來我介紹一種用數(shù)學(xué)建模軟件Mathematica建模的方法
mathematics和MATLAB其實(shí)建模效果是一樣的
