Python&Matlab实现樱花的绘制

作者:电力系统与算法之美

正值樱花飘落的季节,本文将利用Python和Matlab分别绘制一颗樱花树,文中的示例代码讲解详细,感兴趣的小伙伴快跟随小编一起动手尝试一下

1.锦短情长

为什么选择这个标题,借鉴了一封情书里面的情长纸短,还吻你万千

锦短情长

都只谓人走茶凉,怎感觉锦短情长?

一提起眼泪汪汪,是明月人心所向?

2. 一场樱花雨(Matlab)

hold on,axis equal
axis(0.5+[-10,50,0,50])
set(gca,'xtick',[],'ytick',[],'xcolor','w','ycolor','w')

number_branch=15;
alp=pi/10;
length_branch=k1*length_trunk;
width_branch=k2*width_trunk;
trunk=[12,0;12,length_trunk];
plot(trunk(:,1),trunk(:,2),'color',[0 0 0],'Linewidth',width_trunk)
begins=[trunk(2,:),pi/2,1];
grow=begins;
plotdata=[0 0 0 0 0 0 0 0];
plotdata(1,:)=[];
for i=1:number_branch
    control=randi(25,[length(grow(:,1)),1])>=10;
    ag=grow(:,3);
    l=length(ag);
    parta=[length_branch.*k1.^grow(:,4).*cos(ag+ones(l,1)*alp),length_branch.*k1.^grow(:,4).*sin(ag+ones(l,1)*alp),ones(l,1)*alp,ones(l,1)];
    partb=[length_branch.*k1.^grow(:,4).*cos(ag-ones(l,1)*alp),length_branch.*k1.^grow(:,4).*sin(ag-ones(l,1)*alp),-ones(l,1)*alp,ones(l,1)];

    congress=[parta;partb];
    grow=[grow;grow];
    judge=[grow,congress];
    judge=unique(judge,'rows');
    grow=judge(:,5:end);
    plotdata=[plotdata;judge];
end
for i=1:number_branch
    temp_w=width_branch*0.8^i;
    temp_branch=plotdata(plotdata(:,4)==i,:);
    plx=[temp_branch(:,1),temp_branch(:,5)];
    ply=[temp_branch(:,2),temp_branch(:,6)];
    plx=plx';ply=ply';
    plot(plx,ply,'color',[0 0 0]+i*[0.3020 0.3020 0.3020]./number_branch,'Linewidth',temp_w)
end
 
bloom_pos=plotdata(plotdata(:,8)==number_branch+1,[5,6]);
scatter(bloom_pos(:,1),bloom_pos(:,2),10,'CData',[0.8549    0.6824    0.6824])
bloom_pos=plotdata(plotdata(:,8)==number_branch,[5,6]);
scatter(bloom_pos(:,1),bloom_pos(:,2),8,'CData',[0.7451    0.5961    0.5961].*0.97)
end
