Difference Between Parallel and Perspective Projection in Computer Graphics
Contents
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.
- Parallel Projection.
- 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. |
