function christmas
% Anselm Ivanovas, anselm.ivanovas@student.unisg.ch
%Basically just a nice plot for some christmas fun.
%3D Plot of a hhristmas tree with some presents and snow
%% setup
snow=800; % number of snow flakes [0 .. 5000]
%% draw tree
h=0:0.2:25; %vertical grid
[X,Y,Z] = cylinder(tree(h)); %produce a tree formed cylinder
Z=Z*25; %scale to the right heigth
%Add some diffusion to the surface of the tree to make it look more real
treeDiffusion=rand(126,21)-0.5;%some horizontal diffusion data
%add diffusion to the grid points
for cnt1=1:21
for cnt2=16:126%starting above the trunk
%get the angle to always diffuse in direction of the radius
angle=atan(Y(cnt2,cnt1)/X(cnt2,cnt1));
%split the diffusion in the two coordinates, depending on the angle
X(cnt2,cnt1)=X(cnt2,cnt1)+cos(angle)*treeDiffusion(cnt2,cnt1);
Y(cnt2,cnt1)=Y(cnt2,cnt1)+sin(angle)*treeDiffusion(cnt2,cnt1);
%some Vertical diffusion for each point
Z(cnt2,cnt1)=Z(cnt2,cnt1)+(rand-0.5)*0.5;
end
end
%draw the tree
surfl(X,Y,Z,'light')
%% View and format
%Use as nice green color map (darker at the bottom, lighter at the top)
r=(0.0430:(0.2061/50):0.2491)';%red component
g=(0.2969:(0.4012/50):0.6981)';%green component
b=(0.0625:(0.2696/50):0.3321)';%blue component
map=[r,g,b];%join in a map
for cnt=1:6
%change the lower part to brown for the trunk
map(cnt,:)=[77,63,5]/265;
end
colormap(map)%set the map
view([-37.5,4])%Change the view to see a little more of the Actual 3D tree
lighting phong %some nice lighting
shading interp %remove grid and smoothen the surface color
axis equal %takes care of display in the right proportion
axis([-10 10 -10 10 0 30]) %give some more axis space (for the snow later)
axis off %but don't show axis
hold on %to draw the rest
title('HAPPY HOLIDAYS')%self explaining
%% Presents
%Draw some presents around the tree (each with random color)
drawPresent(2,-4,0,3,3,2);
drawPresent(-4,3,0,2,3,1.5);
drawPresent(5,3,0,4,3,3);
drawPresent(-14,-5,0,6,3,1);
drawPresent(-9,-10,0,2,2,2);
drawPresent(0,4,0,4,3,3);
drawPresent(-6,-13,0,3,3,3);
