As the real cube, its shadows looks.
Sideways we add still as the shadow will be placed. The light source to be on the right from above.
We paint over a shadow and we shade. Already show us a cube not the top view, but review points.
We shade the parties.
Napkin which shaded, we are taken place on outer edges to create light tone. Then we take a ruler and a rubber, and an edge of an eraser we equal the parties of a cube.
We do more dark shades.
A little from above we cut off a sheet of paper, flowing round part of a corner of a rhombus.
We put subjects on paper for giving of more realistic image of a 3D cube.
Watch still a 3D cube rubik, a 3D ball, a fence, nuts.
