Reallife Perspective

Parallel Lines Fence

Weak parallel lines of fence.

In some drawings, the vanishing points may be off the page; construction lines may still help with building the image.

Weak parallel lines of fence.

Vanishing points only occur if parallel lines are present in a scene. Many natural scenes have no - or only weak - parallel lines.

THE DEVELOPMENT OF PERSPECTiVE

Geometric perspective as used today was developed in Italy in the early 1400s, when Renaissance artist Filippo Brunelleschi painted the outlines of buildings on to mirrors, and observed that all the lines converged on the horizon. Before this innovation, the main method of showing distance was to overlap forms, which made for very poor architectural drawings.

Axonometric drawing Ignoring the foreshortening effects of perspective can result in an axonometric drawing, where verticals and horizontals are drawn to scale regardless of their distance from the viewer. The technique is widely used by architects.

Composition Perspective Images
Axonometric drawings allow architects to measure directly from the drawing, knowing that the scale is correct.

Partial transparency reveals the structure of the building.

Color in space

Before the advent of linear perspective, artists used color to suggest scale; bright figures and objects were read as being close, and therefore important in the composition. Color, combined with formal perspective, still plays a vital role in establishing depth. Color has a direct psychological effect on the viewer in which warm colors appear to advance, while cooler blues and greens appear to recede.

Subverting illusion

Absence of contrasting color tends to flatten an image, as does using color out of tonal sequence (right).
