Two point Perspective

                            What happens when another vanishing point appears in one point perspective?

It becomes two point perspective!

Two point perspective is most people's favourite perspective to use because it shows a lot more information in an image and gives images more of a 3-D look.

Below is what two point perspective can convey: 

Scale                       Discovery

Controversy        Travel

Transitions

Knowing the Axes

Learning perspective requires the understanding of the X-Y-Z Coordinate system.

Each of the axes points towards a vanishing point and each plane is 

perpendicular to it's axis, as seen in the image below.

This understanding will help you break down the complexity of an image or object and 

will help you stay in control of your image. 

This image below shows what planes are affected by each axis. 

It's not just the large planes on the object that are affected, but the small ones too.

 Other uses for two point perspective 

As mentioned at the top of this post,
two point perspective helps to show more information about an object.

It is especially useful for showing vehicles, props and buildings in concept art. This is because it is a more natural view of the object which communicates scale and details clearly.

What not to do

A common thing that people get wrong in two point perspective is that they have 

the vanishing points too close and they are both in the picture plane. 

This will give it an unattractive fan look in which everything is in the cone of vision. 

The resulting central line is also unappealing.

 

The right way

The image below shows the right way of approaching two point perspective.

Placing the vanishing points further apart, then planning your view of the image 

will give you more freedom in placing the picture plane.

Exercises

These exercises are just like the exercises in the last post about one point perspective 

but using two point perspective instead.
