Eye level and one-point perspective

Your hallway, then a street

Find the eye level, place a vanishing point on it, and draw a corridor and a street in one-point perspective.

2H, HB, 2B

Why this one

  • Unit 4 of the program: Line: the Draughtsman's Half.
  • A corridor and a street where every receding line meets at one point on the eye level, every vertical is plumb, and every cross-line is level.

The plan

  1. 1

    Find your eye level

    17 min

    Stand at the end of a hallway. Hold the pencil level at arm's length: whatever it covers on the far wall is your eye level. Notice that the floor lines rise toward it and the ceiling lines fall toward it. Sit on the floor and watch the eye level drop. That line is attached to your eye, not to the room.

    The hallway

    17 min

    Draw the eye-level line faintly across the sheet. Put a dot on it where the hallway's far end is. Sight the angle of the floor's left edge and draw it; it should aim at the dot. Same for the right edge, the ceiling edges, the top of the skirting. Door frames stay plumb. Cross-lines stay level.

    A street

    17 min

    From the photo, same method. Eye level first (it runs through the heads of any standing figures). Vanishing point. The two building fronts as receding lines. Then window sills and lintels, all aiming at the dot. Meryon's Petit Pont will show you the eye level through the figures on the quay.

    Self-check

    5 min

    Tick each item honestly. If one is a no, the session is not finished; go back to that step.

What it should look like

  • A corridor and a street where every receding line meets at one point on the eye level, every vertical is plumb, and every cross-line is level.

Where it goes wrong

  • Vanishing point above or below the eye level. Placed by guess. It is on the line. Always.
  • Verticals leaning inward. They started converging like the receding lines. Check each against the paper's edge.

Log this session

Start the clock when you pick up the pencil. Stop it when you put it down. Log it. Every session counts toward the box.
