This article mainly introduces how to use Matlab to draw a lovely pumpkin, the text is very detailed, has a certain reference value, interested friends must read!
Effect and Principle
The effects are as follows:
Adjust the data and change it to triangular eyes:
principle
The pumpkin body function comes from a graph of Zhiyou [Nine Chapters Algorithm], which is roughly a piecewise function of the melon body and handle, and then rotates around the z axis to get a curved surface. I have made fine adjustments to the values. The original image and the original data:
implementation method
Here I deliberately kept the grid to make the pumpkin look a little bit like a rag doll.(You can also rewrite it according to your own preferences, such as setting 'EdgeColor' to 'none' and lighting it up.)
% construct grid [t,p]=meshgrid(linspace(0,2*pi,200),linspace(0,pi-.05,200));% bivariate piecewise function foutline=@(t,p)(p.14).* (cos(20.* t)+70).* (p.* (pi-p+.1)).^. 2;% spherical coordinates converted to X,Y,Zh=cos(p).* foutline(t,p);R=sin(p).* foutline(t,p);R=R;X=cos(t).* R;Y=sin(t).* R;% Color matrix construction CMap=ones([size(t),3]);tMap=ones(size(t));c1=[253,158,3]./ 255;c2=[76,103,86]./ 255;for i=1:3 tMap(:,:)=c1(i); tMap(p50&maskX130&maskY45&maskX90&maskY85&maskX90&maskY45&maskX90&maskY80&maskX90&maskY45&maskX90&maskY-35))=1;% mask(maskX>45&maskX90&maskY80&maskX90&maskY45&maskX90&maskY80&maskX90&maskY
