# Difference Between Parallel and Perspective Projection

## Difference Between Parallel and Perspective Projection in Computer Graphics

### Parallel and Perspective Projection Comparison

• Process of converting three-dimensional coordinates into the two-dimensional scene is known as projection.
• There are two projection methods namely.
1. Parallel Projection.
2. Perspective Projection.
• The Key Difference between Parallel and Perspective Projection is that Parallel projection represents the object in a different way like a telescope. Perspective projection represents the object in three dimensional way.

### Comparison Chart

Parallel Projection Perspective Projection
1 Parallel Projection represents any given object in a different way like a telescope. Perspective Projection represents any given object in a three-dimensional manner.
2 In Parallel Projection Centre Of Projection is located at infinite. In Perspective Projection Centre Of Projection is located at a finite point in 3 spaces.
3 Give an accurate view of an object. Can not give an accurate view of the object.
4 Projection lines are parallel to each other in Parallel Projection. Projection lines are not parallel to each other in Perspective Projection.
5 A projector in parallel projection is parallel. A projector in perspective projection is not parallel.
6 Parallel projection divided into Two type

1. Orthographic Parallel Projection
2. Oblique Parallel Projection
Perspective Projection divided into Three type

1. One point perspective
2. Two point perspective
3. Three point perspective
7 Parallel Projection does not generate a realistic view. Perspective Projection generates a realistic view.
