NOTE

PERSPECTIVE DRAWING

Perspective in art usually refers to the representation of three-dimensional objects or spaces in two dimensional artworks. Artists use perspective techniques to create a realistic impression of depth, 'play with' perspective to present dramatic or disorientating images.

Types of perspective Projection

Perspective projections are methods used in drawing to represent three-dimensional objects on a two-dimensional surface. Here's a brief overview:

1. One-Point Perspective (1PP): In this method, all lines converge to a single vanishing point on the horizon. It's often used for portraying objects viewed directly from the front.

2. Two-Point Perspective (2PP): This projection involves two vanishing points on the horizon, typically used when the object is viewed at an angle, showing two sides. It creates a more dynamic and realistic representation.

3. Three-Point Perspective (3PP): This projection includes three vanishing points – two on the horizon and one above or below. It's commonly used for portraying tall buildings or objects when viewed from an extreme angle.

Basic rules of perspective Projection

1. The farther an object is from the drawing plane, the smaller its perspective image in the drawing plane.
2. Lines that are mutually parallel and parallel to the drawing plane are depicted as parallel.
3. Mutually parallel lines that are not parallel to the drawing plane are depicted as intersecting lines.The intersection point is called the vanishing point.

EVALUATION: 1. What is perspective projection?

1. Identify and describe the types of perspective projection
2. Construct the object below in a one-point perspective view.
