>> Hi, I'm Amanda, a Community Manager at Epic Games.
And today we're talking about interactive 3D.
We're experiencing a major shift in the way
we work and communicate.
We've moved from text and images to video.
And now to a world where interactive 3D content
is the norm.
We're going to explore the technology that powers
interactive 30 content and the skills that
will be important in this immersive new world.
What do we mean by interactive 3D?
What we're really talking about is the ability
to interact with the digital world
the same way you do with the real one.
Playing a game like Fortnite on your phone or computer
is an example of this, or it could be a virtual reality
or augmented reality experience where
you need to use special glasses or hardware to view and take part.
But interactive 3D is not just for entertainment.
Now it can simulate the real world in a meaningful way.
For example, doctors can practice surgery
before ever touching a patient.
And it's possible to not only simulate what a surgeon would
see during the operation
but also how it should feel.
Car designers can try out new designs more easily.
Usually designers start with a full sized clay
model of a new car and that can cost a lot to produce and take
weeks to make.
Now they can try out and make changes
to their designs in a virtual design space.
And we can experience this in our everyday life too.
Before you buy a new cool graphic tee
you can turn around a digital version
and look at it from every angle or even
customize it with your own colors and designs.
So how does this work?
The technology that powers all of these experiences
is called real-time rendering.
This is how The Weather Channel creates realistic simulations
of hurricanes and storms that the newscaster can
interact with on screen.
In a traditional 3D animation,
the film you are watching is made up
of a collection of static images that are rendered by a computer.
Rendering is a process of converting a 3D model
to a 2D image.
Oftentimes it can take a computer or a collection
of computers days, weeks, or even
months to render an entire film.
To further complicate things if an artist wants
to make even the smallest change the entire thing
has to be re rendered.
With real-time graphics,
the 3D computer generated visuals
that you see are rendered and displayed almost instantly
making it easy for a director to make changes to special effects
instantly and collaborate on a virtual set with actors.
A real-time engine is the software
needed to create these immersive experiences
and Unreal Engine is an award winning real-time engine.
We call it an engine
but it's not like a car engine.
It's actually computer software created with code.
Their creation process for interactive 3D
involves bringing 3D models into a real-time
engine where behaviors and intelligence can be applied.
This can include lighting, materials, physics,
AI or artificial intelligence, user interaction, audio,
animation, VFX, cinematics, and more.
The result is not a simple image but a 3D world
that you can explore and interact with.
As you move around your view of the world changes
and you get to see different things
as though you've stepped inside a film.
As the industry changes
and we start to see interactive 3D everywhere,
the demand for people to create these experiences is
skyrocketing.
Real-time 3D skills are in huge demand.
In the future, everyone will be a creator.
