Paper-thin Virtual Architecture Part 1

Hello and nice to meet you, my name is sabakichi, and I am a extended experience designer.

While working as a spatial designer, I enjoy creating Virtual Scenes and Experiences in the virtual world.(‘Extended Experience Design’ is a word that I invented, for the new way of thinking needed for ‘how to create and design new experiences in the new virtual era’.)

In this article series ‘Creating a virtual space’, I want to introduce and let my readers experience spatial designing in the virtual world. In each article, I will set a focus point to explain the unique natures and richness of virtual spaces, and the new potential that it holds.

For part 1 of my series, I want to talk about Architecture and spaces in the real world, and the virtual world. Then, I will go through a tutorial so that you can see what is possible in VR.

What is a virtual space?

So, what is a virtual space?

A virtual space is a information area that is created using 3D models and 3D technology.

In order to access these virtual spaces, one needs virtual reality equipment (such as Oculus or HTC VIVE). A ‘virtual space’ is the container, or saucer for these new fictional experiences.

It is a sort of abstract idea, but I am sure you have seen such a scene in science fiction movies. For example, in the Matrix Trilogy, mankind is sleeping continuously, but they are living and feeling inside a world almost as real as reality that is created by computers. The ‘computer generated world’ in this film is a virtual world created by virtual reality technology, and there exists many spaces that form a world. Those spaces, are the ‘virtual spaces’I was talking about.

My introduction became longer than I intended, but this abstract, science fiction dream is now a real technology!

There is no solid answer to the question, ‘What is a virtual space?’ yet. This is because people have only started to use virtual spaces. Yes, one can answer the basic concepts, but how it should be used, and what experiences it can create is still unknown. The fact that one can try to search for the answer that nobody knows yet, is another reason that creating virtual spaces is so interesting now.

Spatial designing and Architecture is more familiar to us than you think

Before going on details for ’spaces’, I have to explain Architecture properly. As nobody can explain fashion before talking about clothes, a space is definitely made with architecture/

.

The word ‘Architecture’ may seem bold, and you may associate it with huge churches or large institutional buildings, but if you think about it, the world and spaces we live in are all created from architecture. Any kind of artificial space is basically includes architecture. Building and designing may not seem familiar to most people, but that is not true.
If there are walls, a roof, a comfortable space, that is a architecture, and we all live in a world created by architecture. Architecture and space designing are very familiar things to us.

In order to live comfortably, we need food, clothing and shelter. We change our clothes everyday, and eat different menus everyday, but we do not change our shlelter space that often. This is because buildings take time to construct, and costs a lot too. But if we focus on our ‘living space’, things become much more familiar. For example, when we plan moving, or ponder on how to place our funiture, one can realize how important space design is.

To simply put it, we cannot live without living space.

Are you sitting in front of your desk now? or are you relaxing on a sofa? By creating ‘a space we belong to’, we are able to put our mind at ease. A ‘space’ is not simply a ‘space’ to us. Anywhere that people feel a strong sense of belonging may be called a living space too. Then, what creates such a place? The situation related to it? or the people related to it?

By examining these facts, we can see that the basic ideas of a ‘space’ originates from architecture, but there are numerous aspects to it. There is an old saying, ‘Everything is an architecture’ but the act of creating and designing such spaces is Architecture. By studying and pondering architecture, I came to the conclusion that spaces can be created from anything.

For example, for an increasing number of people, social services such Twitter and Instagram is where they belong. When you look at your mental home across a screen, where does your consciousness exist? Is it inside the SNS server or in your smartphone? There is no ‘real’ space there, but a living space as a structure can exist. VR technology may be able to visualize such electronic space.

Real? Virtual?

This whole article is becoming very complicated, so let’s stop around here and think about what a virtual space is.

In the first part of my article, I talked about how a space is not limited to physical ones, and may exist from various elements. A ‘space’ may be a mental space, and such spaces previously only existed as data, only visible through devices such as smartphones. But I believe that virtual technology may be able to create and visualize such spaces.

Or, we can make it more simple, and imagine a 3D space for each SNS, where people can communicate freely with each other. There are already such services in use, and are called social VR services.

I’m sure that by now, you will agree that a space, whether it be physical or mental, holds the same meaning to whom it concerns.

I sometimes see people trying to compare real spaces and virtual spaces, but I think that is nonsense. What can you gain by comparing the internet, or a game world with reality? It doesn’t matter if the space is physical or digital. It may even be in between, as in MR. Some people may even find virtual spaces much more precious.

In the new future, ‘how to create virtual spaces’will become a much more popular question. My introduction became longer than I intended, but what I want to do is to consider what I want and desire for new virtual spaces.

Virtual Architecture

Well then, before we start constructing a virtual space, let’s sort out what we need.

For now, VR platforms such as STYLY use game engines for creating uses.(STYLY also supports creating via the web). Game engines combine 3D models with other elements to create worlds and spaces.

To create a real world space, an architecture is needed. This is because a ‘space’ is a concept to show what “isn’t present”.
Take a cup for example. A cup’s use is to hold liquid so it does not spill. In order to achieve such a function, a cup is created so it has a space that holds nothing, where it can hold something.

For a space to exist, there has to be an architecture like a cup. (Of course, there may be exceptions).

In the physical world, there are many architectural styles such as wooden, steel frame, masonry,and so on. There are many reasons for this, but one large reason is because of geographical reasons and a result of physical environments. But in the virtual world, there are none of these external factors, or one can even choose what environment he or she wants, meaning that creators can construct completely new, and pure virtual architectures.

Next, I will talk what forms a virtual world cup could take.

Structures and surfaces / Escaping from the prison of volume

What are the differences between real world and virtual place design? For this chapter, I will compare existing real world architectural styles to those in virtual, so you can see the differences with your own eyes and understand the reasoning behind. (I use the term “real world” as a word meaning the physical world that our bodies are living in).

If you simplify the basic concept of real world architecture, it eventually becomes simple shelter. A shelter is constructed by a simple space separated from the outside by boundaries.

Conceptual diagram of shelter

Imagine a cave, or a house made with just a roof.

An igloo made by children is also a good example, and shows how simple a shelter is. A shelter is necessary and sufficient in the real world, where humans need to protect themselves from enemies, or from the wild.

Well then, what will a shelter look like in the virtual world?

Are there any enemies? In a social virtual platform, there may be. There is a possibility some unhearted person could attack you in some way. But, unlike in the real world, there is little possibility that enemy will be able to attack you physically. The need for shelter as protection may be not as important compared to the real world. Instead, protecting yourself from sight may be higher on the list for virtual spaces.

What about external environments? There is no need for this. You can even control physic laws in the virtual world. You could create harsh environments if you desire, but that is another story.

Which means, a virtual space may be even more simple than a shelter.

 

Next, let’s think about the boundaries to separate the inside and the outside.

In the real world, boundaries are created from walls and roofs. By transforming objects, it protects the inside from external factors. Because of this, there has to be some amount of volume in order to act as protection.

 

architectural_border_image

Ideal, and realistic border volumes

 

Ideally, you want to make borders as thin as paper, but in order to fulfill it’s means, this is still impossible in the real world. But that is not true in the virtual world. There are no external factors, meaning you can use ideal paper-thin walls as boundaries.

Virtual worlds are made from surfaces. 3D models do not have any volume. Since no one can see through polygons, no volume is needed inside.(To be precise, there are certain industrial models that have volume, but we will ignore that for now)

So, all the 3D models you see in the virtual world, have pseudo volume but are in truth paper-thin existences. Ideal borders for a shelter are paper-thin walls, and you can realize how that can be achieved in a virtual world.

Let’s try and see what a space that is created from only paper-thin surfaces looks like.

Constructing samples

Let’s think what creating a space with just surfaces is like.

Simple examples would be a dome shaped shelter, and a box shaped shelter.

 

simple_surface_architecture1

A simple dome shaped virtual construction

simple_surface_architecture2

A simple box shaped virtual construction

These are simple ideal structures took from the real world, but as I mentioned before, the spacedoes not need to be completely separated. Let’s see what happens if we change the surface.

 

variety_of_surface1

Use slits for the surface

A surface can separate the inside and the outside. But creating slits, and adding angles to a surface weakens this function.

This idea is used for louvers in the real world, but in VR, the surface is used directly as boundaries, making it very uniques.

Let’s look at another example. To weaken the separating function of the surface, I changed the transmittance. This will be very hard to do in reality, but in VR, it can be adjusted by a simple slider.

 

variety_of_surface2

Controlling borders by changing the Transmittance

Another characteristic, intensity has been added to the walls. I think this is a very VRish technic. In worlds such as social VR, where visibility is a large factor, this technique could be a important factor.

Lastly, please let me introduce computer generated structures.
This scene is created by randomly lighted or shaded polygons.

 

random_generated_space

A space created by random surfaces

In this sample, the borders are very loose and obscure.

You can see that the boundary factor of surfaces are weakened in this scene. By fragmenting the surfaces, the surfaces created dispersed borders.

This was a simple sample, but I think you were able to take a glimpse at a new kind of spatial representation only possible in virtual.

Exceeding reality with virtual reality

As in my sample, in the virtual world, one can create spaces that cannot be created in reality very easily.

For the experiencer, the space feels as a space, whether it be reality or virtual, and it may be possible to create a truly rich and comfortable environment that nobody has ever seen before. Of course, I believe that one can gain precious experience and use it effectively in reality too.

You need to learn the basic functions of game engines, 3D modelling software, and the difference for each platforms, but by just that small effort, you can start exploring the newest technology areas before anyone else.

I hope you will try building your very own ‘Virtual space’.

In my next article, I plan to talk about the relationship between visible and invisible. Make sure you don’t miss it!
