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.

One point Perspective

When people start getting into drawing, they tend to use one point perspective a lot.
Some people dislike it - they think it's very dull, too simple and seems amateur.
But people often underestimate it.  One point perspective can actually convey a lot of meaning and power.
It's also great for showing depth if done well and it's nice to use for symmerrical images or designs.

Below are strong impressions that one point perspective can convey:

 Battle                                           Religion

Power                                        Wealth

Empires                                    Importance 

Informative

Exercise 01

A fun exercise to get to know one point perspective better 
is to create your own factory or garage. 
Make it full of boxes and other objects that belong in a 
 factory or garage. If you find it to hard to draw 
other detailed objects you can just stick to boxes.
(Always keep in mind the planes of the boxes in relation to the vanishing point).

                   Exercise 02

 Here are three rough drawings I drew in one point perspective, but the horizon line in each drawing is in a different place. The images below have the horizon line at the top, then in the middle, then in the bottom.

So this exercise is for you to draw whatever you want but to have the horizon line in a different place each time.

Perspective terminology

Let's get ready to learn the terminology of perspective and understand it too. There's a lot to remember and understand, so hang on and let's take it step by step. 

Knowing the fundamental rules of perspective and piecing them together will 

help you to make a more realistic picture.

This post will explain the rules that exist, which will help you to create the best illusion on paper. 

Knowing these rules will also mean you can choose to break them if you want to.

The image underneath shows the perspective terminology relating to what can we see.

                                   Here's a GIF showing the terminology in play step by step 
                                      from the Station Point (the person's point of view):

                                         

The next image is a different setting, looking through the Cone of Vision.

It shows how the proportions of objects outside of the Cone of Vision become distorted 

and this creates another vanishing point.

A good way to understand how objects are affected by the Horizon Line is to use a cup! 

Hold the cup out in front of you - when it is straight out in front of you, if you don't see the bottom or the top of the cup it's where the horizon line is (middle cup in the picture below).

If you move it down lower and you can see the top, it's below the Horizon Line (bottom cup)

When you hold it above the Horizon Line, you see the bottom of the cup (top cup) 

This trick can help you to see the effect of the planes on other objects in relation to the Horizon Line.

Helpful terms to know

Here are some great geometric terms to learn, they may be used when talking about perspective 

and will help you understand more of what's happening in an image. 

                                       (Oblique Angle)                                  (Right angle)

                                            (Parallel)                           (Obtuse angle) & (Acute angle)
