How to plot 3d boxes in the most efficient way?

Hi,

I am working on a 3d matrix and I want to plot cubes or spheres for each point in 3d axes.

I tried plotcube function from the file exchange (<http://www.mathworks.com/matlabcentral/fileexchange/15161-plotcube>) but it really slows down the plotting.

I need something like the "line" command instead of plotting lines in traditional way.

I want to plot presized cubes/spheres at user defined points without slowing down plot screen.

What is the most appropriate way for that?

Thanks in advance.
