Create voxels from a sphere pack and store as boolean -


i'm trying convert output file matlab code has output of position vectors , sphere radius. intend create voxels these spheres , store in boolean form i.e 1 sphere, 0 void. please how advise go this. here's example of output.

pos (x) ,       pos (y),        pos (z)        radius      -0.34316     -0.18477     -0.00897   0.0900     -0.18425     -0.20463      0.08040   0.020     -0.46883     -0.49809      0.36954   0.020      0.24727     -0.19437     -0.28274   0.0876      0.39771      0.49293     -0.49469   0.0200     -0.04368      0.26251     -0.07504   0.0200     -0.34705      0.04092      0.37070   0.0200

here's snippet of matlab code i'm working with. spheres in lattice space.thanks

coords=zeros(n,3); % list of 3d positions of particles  overlap=(6*phi/(pi*n))^(1/3);  % create initial, evenly-spaced lattice numcell=(ceil(n^(1/3)));  cellside=1/numcell;  hh=linspace(-.5+.5*cellside,.5-.5*cellside,numcell);  ii=1:n  coords(ii,1)=hh(ceil(ii/ceil(n/numcell)));  coords(ii,2)=hh(floor(mod(ii,ceil(n/numcell))/numcell)+1);  coords(ii,3)=hh(mod(ii,numcell)+1);  end                                scatter3(coords(:,1),coords(:,2),coords(:,3),'filled');
