Rectilinear objects
in one- and two-point perspective
Duration: 90 min.
Subject:
Rectilinear objects (card
boxes, stools, tables, desk
other pieces of furniture in
your bedroom or home,
large and small hard surface
objects, plus a few small
details – a vase, cups, pots,
a desk lamp, etc.) set in the
corner of your room,
kitchen, or hallway.
Be sure to send me pictures
of your set up and your
specific view you decide to
draw from for my approval
before you start drawing.
Technique: measured,
direct observation adhering
to laws of one- and/or twopoint perspective
Materials: Any combination of 2B, 3B, & 4B pencils on 18x24 inches Strathmore paper
Goals:
See and apply the rules of linear perspective to objects observed in your environment.
This drawing allows you to see the connection between careful/analytical observation
and application of laws of perspective that if used in combination improve the illusion of
space. Review elements & principles of design that create depth (diagonal line, overlap,
scale, value) and gain a firm understanding of a cone of vision, horizon line, converging
lines (Orthogonals), and vanishing points.
Method
1. Set up various rectilinear objects against two walls meeting in the corner of your
room/home interior and position yourself facing the corner best several feet
away from you. It is important that you preserve the biggest possible distance
between you and that corner.

2. Start with light gesture of the two walls meeting in the corner (make sure that
the corner you draw is in your picture plane slightly off center and not in the
exact middle of the page.)
3. Work intuitively at first. Draw all the shapes quickly the way you see them. Then
pause and take/check measurements (proportions, angles, relative sizes
between objects on/at walls, and on the floors, ceilings).
4. Once a reasonably accurate drawing has been achieved by eye in gesture, focus
on one large rectilinear object in front of your still life set up (such as a card box
in the image above.) Carefully transfer observed angles of top edges of that
object and simply extend by drawing them as orthogonal lines beyond the
picture plane. The horizon line and vanishing points can be established at the
intersection with the two receding edges, which, as extended lines, became now
converging lines of the object.
5. Be prepared that in the process of establishing all these elements, the lines,
angles, and vanishing points may need to be slightly readjusted and redrawn a
few times until they appear correct.
Questions to consider
•
•
•
•
How effective is the use of design principles (Composition)?
How well do you use measuring methods and line in describing the quality of
objects, their volume, and space (Skill / Proportion/Rendering form)?
How neat/clean is your drawing technique? Work presentation and paper
preservation (Craftsmanship)
How well do you apply concept of one- and two-point perspective? Does your
drawing adhere to laws of perspective (ability to rely on orthogonals when
drawing receding edges, consistency in converging lines at o two vanishing
points on the shared horizon line); expressing space through line variation,
overlapping, definition of shapes and scale
