Color Blob Cube

on 19 Oct 2022

% Color Cube made of blobs

% Step one, set of vertices that make up the cube.

n=5;

v=zeros(0,3);

for x=1:n

for y=1:n

for z=1:n

v(end+1,:)=[x y z];

end

% Create the blobs and call isosurface

b=64;

B=blinnblob(v*10,b,b,b);

S=isosurface(B,.5);

% Cube runs r,g,b across the 3 dims, same as the vertices

% so by rescaling vertices into 0..1, it will get the right colors.

S.FaceVertexCData=rescale(S.vertices,0,1);

% Make it look nice.
