Transcripts

hi everyone well thanks for joining

um i i'm hoping that you guys can

see me now and and hear me as well

right i'm seeing some of you you're not

enhanced that that's great all right so

uh this is going to be 4 600

introduction to computer graphics

uh my name is januxil i'm going to be

your instructor for this course

um so today

my topic is

how this is going to go i'm going to

talk a little bit about computer

graphics

this is going to be a relatively light

lecture and um then i'm going to open it

up for

questions right so that's the that's the

idea from there just they have

so my camera is over here

you guys are over there so when i look

like i am not looking at you

that's when i'm going to be actually

looking at you so

don't feel good that i'm looking to

decide all right so

um first things first uh

so this course right now you're all

joined in zoom which is great this is

one place where you can

see this content and everything um it's

it's

it's nice i i like this i'll be able to

see you you can you guys can see me you

can

talk and i can hear this is all

interactive and i like that and i like

to keep my lectures interactive so it's

all good

um but sometimes you might have some

quality

issues so i'm not sure how

good the quality is on your hand like

when you look at these

these letters if they are looking sort

of pixelated sort of

blurry in some ways that means that

probably the quality of video that

you're receiving on your end

is not very good in zoom that's what it

means so

to alleviate this potential problem if

you're experiencing it

i'm also live streaming these lectures

on youtube

so that's the other option you can go to

youtube um

just go to my channel slash live

these lectures are publicly streamed

let me start by saying that i am

teaching this course for the very first

time

now i'm very familiar with computer

graphics but i haven't taught this

course

in the past uh so the problem for me

with that is that i just took over this

course couple of weeks ago

that means i need to prepare the whole

content for the

entire course now i didn't want to rely

on existing content i actually

uh wanted to sort of redesign this

course

uh so if you guys are familiar with how

this course

went in previous years this is going to

be slightly different of course there's

going to be a huge overlap in terms of

content

but it's not going to be 100 overlap

this is going to be um

my version of of this course and

how i think this course should be

thought um

but the caveat for me is that i'm going

to have to prepare these lectures

uh throughout the semester and that's

going to have some implications on you

that is

you know i'm not 100 sure exactly how

this course is going to go i think it's

going to go well

but that's not my point my point is that

i'm

you know i may need to shift things

around as we move forward

when i have better ideas about how this

course should be structured

right all right so let's um

jump right into computer graphics we

presumably

that's why we all are here so the three

pillars of computer graphics are

as i like to call them that it's that's

modeling

and rendering and animation right

modeling

is the the the process of

generating of the designing as some some

object some visual representation of

something this could be a 3d object it

could be something 2d doesn't have to be

3d

modeling is the the is the process where

we generate the data that we're going to

use for

all sorts of computer with us and there

are um

tools all sorts of tools out there for

modeling and there are also sort of

algorithms and data structures

out there for modeling in this course

we're going to concentrate on

the the math we're going to concentrate

on the algorithms we're going to

concentrate on the data structures of

modeling

we're not going to concentrate on the

tools how to use specific tools

we're not going to cover that part at

all we're just going to deal with the

computer science related part of it

right

the other pillar is rendering that's the

process of

generating images um that that

involves a whole bunch of things you get

the

data uh from from the model data and you

you generate an image a 2d image that

you look at at the end so that's the

final

output that you you wanted to use in

computer graphics

um rendering involves a lot of pieces in

this course we're going to cover some of

the basics

we're not going to go too deep on

every little detail but we're going to

cover the the main concepts behind

uh rendering right

the other one is of course is is

animation

and animation can be done in various

different ways uh

of course with with computer graphics

oftentimes we have

animating objects we have moving objects

we have deforming objects like

like in this example and they could be

generated in various different ways and

we're going to talk about those in a

little bit

so these are the the three pillars of

computer graphics

that we're mostly going to uh talk about

in this course

but this doesn't really this doesn't

really cover everything that's going on

in computer graphics computer graphics

is actually

a very wide and never expanding field

um and a whole bunch of other things

that can be considered

a part of compute graphics besides these

three core areas

for example using interaction is

oftentimes considered a part of cookie

graphics

and all sorts of user interaction tools

and

techniques uh visual reality obviously i

mean part of it is definitely computer

graphics so of course there are there

are parts

that may be arguably computer graphics

maybe not but you can think about

the whole concept of virtual reality as

a part of computer graphics

and of course if visual reality is

computer graphics then you know

augmented reality is computer graphics

too right

uh an organic value could be something

like this you're just

holding the enterprise or just you're

wearing some some goggles that

see-through bubbles

uh that's not visually augmented reality

is happening right

uh so you guys know the difference

between virtual reality and augmented

reality

in the visual reality you completely

lose

your connection with the actual reality

in augmented reality the

actual reality exists you just add stuff

to it you add some visuals to it so

that's why we're using

see-through glasses with augmented

reality or in the other example we're

using

a camera that's actually seeing the

actual scene

if we don't see anything at all if

everything is completely covered that

that will be visual reality

all right let's let's move on uh

visualization

is a field of its own but it's also

considered a part of computer graphics

while some people do

consider part of computer method

image processing is another um is

another

component of computer graphics in this

case you know you stop in an image and

you manipulate it with using all sorts

of algorithms

uh for this example if you're trying to

understand what's going on here there's

some cards

at the bottom here and the algorithm

sort automatically deletes those cards

and they don't exist anymore so this

doesn't

quite perfectly fit in our modeling

animation rendering paradigm but still

it's considered

image manipulation is considered a part

of computer graphics by most people

another one is a big one actually is

computational photography

so um this this is the

the process of uh generating photographs

so taking photographs

using computational tools so the actual

goal here is to take a photograph

but you don't want to just rely on a

good old

camera either analog or digital camera

but you want to

add some computational tools uh to to be

able to do things that you couldn't do

with with a regular camera

combining algorithms to enhance the

process

of capturing images uh

or being able to do stuff that you

couldn't do just by a

regular visual camera like this called

computational photography photography

3d scanning is definitely a big part of

computer graphics

this this can be considered a part of

modeling and

one way of generating model data could

be using 3d scanning tools

and if 3d scanning is a part of graphics

then

fabrication can also be considered a

part of graphics right

so in this case where taking some

bottles and we're converting them into

into

actual physical objects these examples

are done

uh through knitting actually these were

done

by hand knitting they could be done

using computer controlled

knitting machines as well of course we

could also have

additive manufacturing using 3d printers

there's a ton of work out there in

computer graphics

related to fabrication yeah so all this

stuff is considered

computer graphics by most people but

let's uh

briefly look at the applications of

computer graphics when i say computer

graphics most people think about

entertainment so let's start with that

the first one is

video games or one of my favorite video

games here

obviously video games are a huge part of

computer graphics and

and entertainment um there's really

i'm not gonna say anymore here

special effects also you start with some

live action and you

add some stuff to it either some

background or some some foreground

objects that's considered you know a big

consumer of computer graphics is also

the special effects industry

uh special effects can be um tools that

combine live action or could be just

purely compute graphics

without using any live action shots none

whatsoever right that's

also considered special effects and a

huge consumer of computer graphics as an

application

feature animation is another one so we

typically separate feature animation

and special effects because special

effects is typically connected to live

action

even if live action does not exist in

all scenes

it exists in some scenes right there

some actors

playing uh in some scenes with feature

animation we don't have any actors

and then the the ultimate goal does not

always have to be

generating realistic images

most often feature animation

would use uh more stylized images

uh and cartoonish looking characters not

completely 2d cartoons uh but

but you know 3d cartoonish-looking

characters is

what uh feature animation would

typically use

of course talking about cartoons

computer graphics is also used

in cartoons as well in this example uh

it's used for generating a background

i'm not exactly sure if this is a 3d

background

but it's definitely something that's

that's computer generated one way or

another

uh and then you can have some foreground

hand-drawn characters on top of that

this is actually a relatively widespread

use case of computer gap it's a

relatively widespread use case of

computer applications uh there are

applications that are outside of

entertainment as well of course

so this is an example that's using

computer aided design and computer

manufacturing uh this is very heavily

used in

all sorts of engineering applications as

you can imagine it's definitely a

big application of computer graphics uh

simulations uh simulations are used for

games they're used for special effects

but they're also used for the purpose of

simulation itself

in this case for example training

uh pilots right so this is another

big application of computer graphics

uh medical imaging is another big

application of computer graphics so

there are various ways that computer

graphics is used

uh in medical imaging as you can imagine

uh and visualization in general can also

be considered a

an application of computer graphics

either information visualization or data

visualization

can also be considered a big application

of computer graphics well basically

anything that involves some visual

component

is an application of computer graphics i

would even include

our cell phones right and the graphics

on those cell phones they

are a big application of computer

graphics

all right so enough about general talk

about computer graphics let's be a bit

more specific and get back to this

course and

talk about what we're going to cover in

this course uh so

mostly in this course we're going to

concentrate on these three builders

modeling

rendering and animation and about

these topics we're going to cover the

algorithms we're going to cover the data

structures

so the cg part of it we're not going to

talk about existing

tools uh obviously

what i would like to do in this course

is to give you a

broad overview of the important topics

in in these three pillars right

so we're going to cover a whole bunch of

topics here so for most of them

we're not for most of them we won't have

time to go into

too much detail and this is by design

because

in an introduction to computer graphics

course i would like you all to be

knowledgeable about all of these things

so this is not a modeling course it's

not a rendering course it's not an

animation course

this is an introduction to computer

graphics course that will cover

everything

to a certain extent right so if you find

yourself

interested in any of these topics any of

the topics that we covered

you'll find that in the university of

utah we have

all sorts of specialized computer

graphics courses

that dive much deeper into these topics

for example i teach uh

two rendering courses one of them is

about interactive graphics is about

interactive rendering

and shader programming the other one is

ray tracing for graphics is about

generating highly realistic images

uh starting from from scratch and we

also have

computer animation courses so if you

find yourself interested in these topics

you can find specialized courses in

these topics but in this course we're

gonna

have a sort of broad uh relatively

higher level overview and we're gonna

cover the basics of these topics right

so this is our textbook it is

recommended

but not required and there's a good

reason for that

while designing this course i actually

had an extensive

discussion with steve martin and pete

shirley those are the the main authors

of this book

and uh you know we talked about all

sorts of stuff and

how this book could be used i i got to

tell you that

both steve marshall and pete shirley are

two

very strong very well known graphics

researchers

but on top of that they are people who

are

really really good at explaining things

uh

so i'm i'm pretty sure you're gonna be

happy with

uh with this book and i i haven't read

the entire book just yet i've read

parts of it uh quite a bit of it

actually and

i've been very very happy with it um and

i'm pretty sure you guys will be happy

with it as well so we're gonna

follow this book let me actually zoom in

but i'm not saying that this is

required this is recommended uh so

my my recommended style for for this

course

for you guys to be able to get the most

out of this course would be

attending these lectures live uh if you

can

uh and listen to this listen to these

lectures

and ask your questions live and then go

back

and and go go to the book and read the

related chapter i'm going to highlight

the related chapter

so i'm not planning to cover everything

that's in the book

right and for the stuff that i cover in

the book i'm not planning to cover

every detail necessarily

but the book is not going to be a full

substitute for these lectures either

because i might actually provide more

information or additional information

that does not exist in the book uh so

that's why i would recommend that you

uh use both these lectures and the book

uh at the same time in connection with

each other so

this particular introduction uh lecture

is related to the very first chapter of

the book

it's not covering everything that's in

the very first chapter but it's covering

quite a bit it has a few additional

stuff in there as well um

but actually mostly i'm talking about

how this course is gonna go

right so you don't necessarily have to

purchase the book

uh if you don't want to we also

as university of utah students you

should have online access to this book

as well the details

are uh you can find the details on on

canvas

there's a fairly easy way of accessing

an online version of this book

using your uh university of utah

accounts

now let's talk about these seven

projects

uh the de facto language of compute

graphics

is c plus plus which we're not going to

use

so a lot of people and a lot of graphics

people

actually really don't like c plus plus

i'm not one of them i love c plus plus i

use c plus plus all the time all of my

other courses use c

plus plus but not this one in this

course we're going to use javascript

and we're going to use webgl uh now

i'm not a big fan of java but i love

javascript

um mainly because it works on the

browser it's

uh it's a your platform independent just

works on pretty much any browser now

it's reasonably fast in the past way

way back when it was kind of slow to

today you can do a lot of really

complicated stuff with javascript and it

works just fine

um so it's uh and and the debuggers

are okay uh not great but it's actually

pretty decent uh i would recommend uh

that you guys use chrome chrome actually

has a very good java debugger javascript

debugger

i i do use that extensively um

and i would i would recommend it um i'm

not sure if there are

other good debuggers for javascript as

well but we're going to be using

javascript

and the main reason for that is that

first of all i wanted this to be

sort of platform independent second of

all i would like you guys to be able to

showcase the stuff that you're doing

easily so this is going to be javascript

so you can just put it on your web pages

and it's going to work right

well i don't want you to be sort of uh

publicly uh publishing your

uh your your projects which is going to

be

a part of plagiarism so we're not going

to go there but you know

at the end of this course you will be

able to easily do stuff

with computer graphics and javascript

and that that's one of my intentions

that you guys will be able to

do this and if you're not familiar with

javascript

i would say don't worry too much about

it because i think you guys

can learn javascript fairly easily if

you're not familiar with it and you

really should be familiar with it it's a

very very

widely used language and and you guys

should know i think

so we're going to be using javascript

and that's going to make things

quite a bit easier uh because um

we're not going to be battling with the

programming language too much uh

doing simple stuff in um

relatively lower level languages like c

plus plus

uh can be can require a bit more effort

uh with javascript things are going to

be quite a bit easier and we can use

html as

our user interface so things are going

to be much easier

uh from user into interface perspective

right

all right guys um thank you all for

joining in

um we'll do the same on thursday so

thursday's topic is going to be some

math background and it's uh

the if you want to take a look at the

related chapter in the book uh just be

warned that the the book

is the chapter two of the book is more

extensive than what i'm planning to

cover it's covering

a lot more math than i am planning to

cover

on thursday so i'm just gonna talk about

a part of it

uh and i'm gonna talk about the rest

when it becomes relevant to the topics

that we're covering

all right thanks for coming in i'll um

i'll see you next time

thank you thank you thank you thank you

thanks
