This will help your cube drawing look more voluminous and realistic. Recall again that the receding lines should become closer to each other and lose in contrast. Note that the top face should be flatter than the bottom one. Now, using four straight lines, depict the top edges of the cube. Recall that, in accordance with the rules of aerial perspective, the lines located closer to us should be darker and more contrast than the lines located further from us. Now, using four straight vertical lines, sketch the vertical edges of the cube.
Recall that in accordance with the rules of linear perspective, the receding lines should be slightly closer to each other. We depict these lines so as not to err in the proportions and fidelity of the angles in the figure. Now, using very light lines, sketch two more edges of the cube that are not visible to us.
