I am trying to plot a rubiks cube, I currently have a 9x2 matrix with the coordinates of the peices. I have a seperate 9x3 matrix that has the color in RGB triplets.

I am trying to find a way to plot this, then eventually I would like to be able to watch it solve a cube.

I have this code here, which uses patch() to create a 3d cube, for some reason, only the top and bottom show up though.

axisLim=5;
figure
hold on 
for p = 1:9; %White Face D
    x = MwCoords(p,1);
    y = MwCoords(p,2);
    patch([x,x,x-1,x-1],[y-2,y-3,y-3,y-2],[0,0,0,0], MwC(p,:))
end
for p = 1:9; %Yellow Face U
    x = MyCoords(p,1);
    y = MyCoords(p,2);
    patch([x,x,x-1,x-1],[y-2,y-3,y-3,y-2],[3,3,3,3], MyC(p,:))
end
for p = 1:9; %Orange Face F
    y = MoCoords(p,1);
    z = MoCoords(p,2);
    patch([0,0,0,0],[y-3,y-3,y-2,y-2],[z,z,z,z], MoC(p,:))
end
for p = 1:9; %Red Face F
    y = MrCoords(p,1);
    z = MrCoords(p,2);
    patch([3,3,3,3],[y-3,y-3,y-2,y-2],[z,z,z,z], MrC(p,:))
end
for p = 1:9; %Blue Face F
    x = MbCoords(p,1);
    y = MbCoords(p,2);
    patch([x-1,x-1,x,x],[-2,-2,-2,-2],[y,y,y,y], MbC(p,:))
end
for p = 1:9; %Green Face F
    x = MgCoords(p,1);
    y = MgCoords(p,2);
    patch([x-1,x-1,x,x],[1,1,1,1],[y,y,y,y], MgC(p,:))
end
hold off

You can just use this MwC for the colors, as an example

Here are the all the coordinates

Sorry for this being a messy post, please let me know any ideas you may have

在 MATLAB Online 中打开

Maybe you will be intersted

create surface

[x,y] = meshgrid(1:5,1:4);
surf(x,y,x*0)

remove unwanted parts

z([1 4 13 16 17 20]) = nan;

assign Z coordinate

z([2 3 5 8 9 12:end]) = 1;

move X and Y coordinate

[x,y] = meshgrid([0 0 1 1 0],[0 0 1 1]);

add for loop

for i = 1:3
    for j = 1:3
        for k = 1:3
            surf(0.9*x+i, 0.9*y+j, 0.9*z+k, 'facecolor', rand(1,3))
        end
    end
end

So i am trying the code at the moment, and I am having some issues. I cannot remove unwanted parts with that line you gave. Whenever I apply the next line of code that you provide, nothing happens to the original 3x4 figure, any suggestions?
