In the previous example, the line that indicated the bottom of the box
and the horizon line were one and the same. But this isn’t always the
case. Often, we’ll draw the bottom of a box or similar object so that it
dips below the horizon line. This results in a slightly more
exaggerated perspective. It also calls for an additional set of
vanishing lines.
- Vanishing point left
- Top left line of box
- Top right line of box
- Vanishing point right
- Horizon line
- Add a vertical line that starts where the two diagonal lines intersect.
Now continue that vertical line below the horizon line. The vertical
line represents the overall width of the box. So decide how you want
the box to be and draw the line to that length.
