Perspective.

Perspective is a tool which allows us to create the illusion of 3D depth, on a 2D surface.

Major Concept.

Diminution.

Concept.

The farther away the object, the smaller it appears.

Objects converge & foreshorten.

Vocab.

  • Horizon Line

    • The height level of the “eye.”

  • X, Y & Z Axes

    • Up & down, left & right, forwards & backwards

  • Face

    • The 6 side planes of a cube

  • Converge

    • Lines get closer together

  • Vanishing Point

    • The point where parallel lines converge towards

Minor Concepts.

Overlap.

Placing one object in front of another simulates depth.

ABO (Above, Below, On).

When an object is below the horizon line, we see the top, when it’s above, we see the bottom, & when it’s on, we see neither the top nor the bottom.

The Cube.

The simplest 3D form. Their are 3 sets of parallel lines & each set converges to their respective vanishing point. You can only ever see 1, 2 or 3 sides of this object.

Crating.

Creating a box around an object before drawing as a 3D guide.

1 Point Perspective.

Looking at the face of an object & all lines converge to a single vanishing point.

2 Point Perspective.

Looking at the corner of an object, & lines either converge to one of two vanishing points.

Elliptical Lines.

As horizontal lines move farther away from the horizon line, the more they bend.

Lens Distortion.

The Tile.

Use a flat 3D square to estimate the footing of a character.

Foreshortening.

The more an object points toward the camera, the flatter it appears.

3 Point Perspective.

Rule of Thumb.

Looking at the corner edge of an object, & lines either converge to one of three vanishing points.

The Brewer Method.

Estimate the angles for 2 point perspective.

Convergence.

As an object turns away, the lines angle more dramatically, and the width of the plane becomes smaller.
