00:00:00,009 --> 00:00:03,003
- [Joel] Whilst creating visualization projects

2
00:00:03,003 --> 00:00:07,000
can be an enjoyable experience, they can come

3
00:00:07,000 --> 00:00:09,008
with their fair share of challenges.

4
00:00:09,008 --> 00:00:12,009
By the end of a project though, the fact that we can see

5
00:00:12,009 --> 00:00:15,008
and experience spaces or environments

6
00:00:15,008 --> 00:00:18,006
that probably don't even exist yet

7
00:00:18,006 --> 00:00:22,007
definitely makes all of the hard work worthwhile.

8
00:00:22,007 --> 00:00:25,001
This process can be taken even further though

9
00:00:25,001 --> 00:00:28,009
when we start to talk about real-time visualizations

10
00:00:28,009 --> 00:00:32,004
as we can now give a user the ability to control

11
00:00:32,004 --> 00:00:35,005
or interact with that environment as well,

12
00:00:35,005 --> 00:00:38,006
making the whole experience feel more personal

13
00:00:38,006 --> 00:00:41,003
and more engaging than just watching a video

14
00:00:41,003 --> 00:00:43,007
or flicking through some still renders,

15
00:00:43,007 --> 00:00:46,004
although it perhaps should be noted that when working

16
00:00:46,004 --> 00:00:48,007
with real-time environments, we can actually

17
00:00:48,007 --> 00:00:51,003
have the best of both worlds.

18
00:00:51,003 --> 00:00:53,006
With this in mind then, we are for the duration

19
00:00:53,006 --> 00:00:56,000
of this course going to be looking at creating

20
00:00:56,000 --> 00:00:59,002
several opportunities inside our office space

21
00:00:59,002 --> 00:01:03,004
to add this extra immersion element to our projects.

22
00:01:03,004 --> 00:01:05,006
So we will see how we can interact

23
00:01:05,006 --> 00:01:08,008
with the computer monitors that we have in the office,

24
00:01:08,008 --> 00:01:12,003
turning them both on and off as well as getting them

25
00:01:12,003 --> 00:01:14,005
to display both video and sound

26
00:01:14,005 --> 00:01:16,005
when the user clicks on them.

27
00:01:16,005 --> 00:01:19,002
We will then see how we can add a switch to turn

28
00:01:19,002 --> 00:01:23,004
any user-selected light fixtures on and off in the scene,

29
00:01:23,004 --> 00:01:26,006
all the while making sure that the tool is flexible enough

30
00:01:26,006 --> 00:01:29,001
to be used with either just a single light

31
00:01:29,001 --> 00:01:32,004
or a whole batch of them, after which we will move on

32
00:01:32,004 --> 00:01:35,008
to building a swinging door that can change swing direction

33
00:01:35,008 --> 00:01:38,006
depending on which side of the door the user decides

34
00:01:38,006 --> 00:01:42,000
to interact with it from, meaning we can be confident

35
00:01:42,000 --> 00:01:44,004
that the client won't be getting accidentally stuck

36
00:01:44,004 --> 00:01:48,005
behind it and thus breaking the illusion of immersion.

37
00:01:48,005 --> 00:01:51,000
Finally, we will create a material that can be used

38
00:01:51,000 --> 00:01:54,006
to add an outline around each of these interactive actors

39
00:01:54,006 --> 00:01:58,002
in the scene so that as the user approaches them,

40
00:01:58,002 --> 00:02:01,005
well, they will know that they can be interacted with,

41
00:02:01,005 --> 00:02:05,004
this requiring the use of several material nodes in Unreal

42
00:02:05,004 --> 00:02:08,001
in order to pull the effect off.

43
00:02:08,001 --> 00:02:10,006
With lots of work to dig into then,

44
00:02:10,006 --> 00:02:12,009
we can get going and dive right in.
