What is Perspective view?

perspective view

Perspective view is a three dimensional view of a different object which shows height, width and real depth of the object’s body when observed by our eye or portrayed on a sheet of paper.

Everything we see in daily life is naturally observed in perspective. Objects like building exterior, interior, streets etc. is what we normally observe in perspective.

What are different types of perspective views

There are basically three types of perspective view – one point perspective view, two point perspective view and three point perspective view.

One point perspective view

One point perspective is a view which has one vanishing point. All the orthogonals of the object are directed toward a single point on the horizon line (eye level).

We mainly observe one point perspective view in streets and railway tracks.

Two point Perspective view

Two point perspective is a view which has two vanishing points; one on each side of the horizon line. 

Right side orthogonals of the object vanish toward the right vanishing point and the left side orthogonals of the object vanish toward the left vanishing point.

Buildings or small objects like rubix cube is what we observe in two point perspective.

Three point perspective view

Three point perspective is a view which has three vanishing points; one on each side of the horizon line and one at the very top of the object.

It is the same as two point perspective view but the vertical lines of the object are directed toward the very top vanishing point.

We observe three point perspective view in tall buildings and skyscrapers.

Bird’s eye view in perspective

When we look at any object from the top, the top surface with one or two sides of the object is seen. That is what a bird sees. So this view is called bird eye view. This view is normally used for visualizing and making urban planning. In a bird’s eye view the observer’s eye level must be above the object.

To observe bird’s eye view in one point perspective, the observer’s eye level should be above the object where all the orthogonals are directed toward a single vanishing point.

To observe bird’s eye view in two point perspective, the observer’s eye level should be above the object where right orthogonals are directed toward the right vanishing point and left orthogonals are directed toward the left vanishing point.

Bird’s eye view in three point perspective is the same as bird’s eye view in two point perspective but the vertical lines of the object are directed toward the very top vanishing point.

Normal eye view in perspective

When we look at any object from a human perspective normal eye view is observed. In this view we can observe the front with any one side of the object. Both the top and bottom side are hidden. Here, the observer’s eye level should be in between the objects. Generally, normal eye view is used for making building exterior with the surrounding landscape and designing interior.

To observe normal eye view in one point perspective, the observer’s eye level should be in between the objects. Here, all the orthogonals are directed toward a single vanishing point on the observer’s eye level.

To observe normal eye view in two point perspective, the observer’s eye level should be in between the objects. Here, the right orthogonals of the object are directed toward the right vanishing point and the left orthogonals of the object are directed toward the left vanishing point on the observer’s eye level.

Normal eye view in three point perspective is the same as normal eye view in two point perspective but the vertical lines of the object are directed toward the very top vanishing point.

Worm’s eye view in perspective

When we look at any object from the bottom, the bottom surface with one or two sides of the object is seen. That is what a worm sees. So this view is called worm’s eye view. In real life it is not possible to see the bottom face of the object unless it is levitated or lifted up. Here, the observer’s eye level must be below the object.

To observe worm’s eye view in one point perspective, the observer’s eye level should be below the object where all the orthogonals are directed toward a single vanishing point.

To observe worm’s eye view in two point perspective, the observer’s eye level should be below the object where right orthogonals are directed toward the right vanishing point and left orthogonals are directed toward the left vanishing point.

Worm’s eye view in three point perspective is the same as worm’s eye view in two point perspective but the vertical lines of the object are directed toward the very top vanishing point.

Conclusion

In this post I have talked about what is perspective view and what are the types of perspective view. Visualizing perspective is not that hard when you know some basic principles of perspective. Perspective rulers will guide us where the orthogonals of the object vanish and it becomes easier to observe perspective in real life objects. I hope this post will help you understand the basics of perspective view.
