I'm trying to draw 2 cubes in one M file. This is my code:
format compact h(1) = axes('Position',[0.2 0.2 0.6 0.6]); vert = [1 1 1; 1 2 1; 2 2 1; 2 1 1 ; ... 1 1 2;1 2 2; 2 2 2;2 1 2]; fac = [1 2 3 4; ... 2 6 7 3; ... 4 3 7 8; ... 1 5 8 4; ... 1 2 6 5; ... 5 6 7 8]; patch('Faces',fac,'Vertices',vert,'FaceColor','r'); % patch function material shiny; alpha('color'); alphamap('rampdown'); view(30,30);
Now, I want to draw second cube and replace inside first one. Does anyone know how I can do that?
Maybe you want something like this:
you just need to slightly modify your original code: 1. define a new cube which should be placed inside the first one. 2. please remember add 'hold on' after 'patch'.
clf;
figure(1);
format compact
h(1) = axes('Position',[0.2 0.2 0.6 0.6]);
vert = [1 1 -1;
-1 1 -1;
-1 1 1;
1 1 1;
-1 -1 1;
1 -1 1;
1 -1 -1;
-1 -1 -1];
fac = [1 2 3 4;
4 3 5 6;
6 7 8 5;
1 2 8 7;
6 7 1 4;
2 3 5 8];
% I defined a new cube whose length is 1 and centers at the origin.
vert2 = vert * 0.5;
fac2 = fac;
patch('Faces',fac,'Vertices',vert,'FaceColor','b'); % patch function
axis([-1, 1, -1, 1, -1, 1]);
axis equal;
hold on;
patch('Faces', fac2, 'Vertices', vert2, 'FaceColor', 'r');
material metal;
alpha('color');
alphamap('rampdown');
view(3);
