The Strangers Guide to 3D Modeling In the Fields of Industry

3D modeling, in its broadest and most common sense is the act of taking simple

geometric shapes such as boxes or spheres and meshing them into a complex creations of any

magnitude. This paper will not be fully about the artistic side or the technical side of these

programs. This paper will not be fully focused on one topic but several. Finally, some of these

parts you might find fascinating and others dull. The range that I will be writing about will

include 4 different fields of industry and will describe how 3D modeling and 3D imaging

technology have improved key areas within them. The access to freedom of creativity has given

birth to many academic, scientific, commercial, and medical achievements throughout the

years. I will write about some of those achievements and their impact of how they have helped

for better procedures with other methodologies on the way things are done.

Before we dive straight into the many different fields where 3D modeling and 3D

imagining are used, I feel that I should explain more about how objects are made using the

commercial modeling programs. The process of making 3D models is rather simple, so long as

you can understand the tools. I have quickly made a short montage of pictures to help show the

process of taking a box and meshing it into a gremlin looking character.

2 3D Modeling Academic Comprehensive Essay

In Fg1, the total amount of time this took me to model the final image was about 15

minutes, which in modeling terms is relatively quick. I would like to apologize for the chaotic

order onto where the images are placed; the images came out a bit too large during the

rendering of each step and I had to resize them as I went along in photoshop. Most projects in

3D modeling take hours to days to complete and are usually comprised with such finite detail,

that takes just as long if not longer to render out (render means for the computer to create the

image or movie with full details in it such as lighting, shadows, effects, etc...) For further

example of rendering time, the movie, Toy Story 1, took an incredibly long time both to make

and render. A quote from an unknown columnist who works at Entertainment Weekly Online


who had a chance for to interview the producer stated that the movie took “A whopping

114,240 frames, 600 billion bytes (1,000 CD-ROMs hold the film's data), 160 billion pixels, and

800,000 machine hours…“ (EW1) The important bit of information here is the number of

machine hours it took for Pixar to render out the movie. Machine hour in technical

circumstances is a term used to state how many hours a computer has been left on to

continuously work on a task.

To further detail, a frame is like a picture. Each frame shows about a seconds worth of

imagery before moving onto the next frame, as in the case of movies. As for still frames, the

picture example I placed above is a perfect example of still frames. Each picture within it is a

still frame which I used to show the progression of making an object.

Now that we have gone over some examples of what 3D modeling is and how it is done I

want to also explain that for some fields of study such as Medicine, 3D modeling is labeled in a

different term and is vastly different from what you have seen and I will explain further once we

get to the subject. Since so far I have been talking mainly about the commercial side of the

topic, let us dive further into how the commercial industry feels about how it applies the use of

3D modeling.

- Commercial

The easiest topic to see the achievements of modern 3D creativity and ingenuity is from

commercially based entertainment. Top class movies like Avatar and Iron Man were all made

possible thanks to the prowess of 3D programs. James Cameron’s co-producer for Avatar, Jon

Landau, stated: “Avatar would not be possible, but for Autodesk. It made the impossible,


possible and for that, James Cameron and I are eternally grateful.” (AD1) Autodesk is the

leading company for innovative 3D modeling software in the world. It is evident how popular

and powerful their tools are, in that their top 2 modeling programs, 3ds Max and Maya,

generate the most competition between themselves, and are the top selling 3D modeling

programs in the world. The reason why Autodesk has become so popular and renowned as a

mainstream producer for 3D modeling software is mainly due to the fact of how old their

company truly is. Autodesk was started up in 1982 which in tech years is relatively old. They

started out with the release of the program AutoCAD, which is an architectural program

allowing users to make detailed and accurate blueprints. They quickly rose in the ranks of

industrial software designers. Each year Autodesk makes an expansion onto their already

existing products, fixing bugs and adding in new features that make new things possible and old

things easier and less time consuming. Having 20 years of experience in designing software and

gaining customers trust, Autodesk has become the ideal group with whom to work and buy

products.

Another reason people prefer Autodesk over the many other companies and groups

who offer efficient and at times free software, is the fact of just how expensive Autodesk

products cost. I know this may sound odd or off to you but the items you purchase from them

are not toys or simple play things, even if they are fun to play with. They are tools in which one

can invest. The current price for 3ds Max with a lifetime license is $3,495. Due to the significant

price for this piece of software, Autodesk makes sure that it’s as bug-free as possible and

provides extensive additional content. They provide tutorials for all levels of experience and

ensure that these can be easily accessed. New versions are available each year or two. There


are many other 3D modeling programs that each have their own abilities and specifications,

and most of these programs are made to work with each other. A quick list of other programs

that work along with 3ds Max and Maya includes:

Zbrush (sculpting and detail adding program),

MudBox (sculpting and detail adding program),

Blender (free 3D modeling program),

Softimage (free 3D modeling program).

Most of these programs are used commercially and have sorts of Terms and Conditions of what

can and cannot be done or used when a project becomes ready to sell on the open market.

A video interview with a cinematic company called Blur, which does many of the

cinematic scenes for video games, gave much insight of how far the program and community of

3D modeling and game production has come. A quote from the interview that really stood out

to me:

If you look at 20 years of evolution of the products, the amount of flexibility that

we have to create. Character, worlds, effects that no one has dreamed of. With 3ds Max

anything is possible… We always have had a partnership with Autodesk. They have been

very attentive to what we need and they really realize that it’s not about selling

software, as much as it is about creating a great product that artists can use. (AD2)


It is through here that we gain some insight of the freedom that these products give to

the commercial world. The ability to be able to create a powerful message, story, or product

through visual art is something that helps build trust between companies and their customers.

Crysis, acclaimed to be one of the greatest 3D graphic games for the PC has always been on

the number one list to make people awe over the cinematic style scenery. The picture

above is a screenshot someone took while in the game to show just how breathtaking the

landscape was. Crysis was released in 2007 and to this day is still regarded as one of the


highest quality graphical games out on the market. This is relevant to 3D modeling because

not only did it allow consumers to own and create completely beautiful virtual worlds but

also forced the commercial companies to compete with this immense leap in graphic design

that game offered. Within 6 months of Crysis being released, 4 or 5 other games with close

or similar quality of graphics were placed on the market. Some used the same game engine

– an extensive program that runs all the behind-the-scene information for the game - and

others used engines that were made from the ground up, since previous models could not

compete. Nearly 4 years have passed since the release of Crysis; a few games have been

released where the in-game cinematics may beat those of Crysis, but not many have gone

beyond what it has to offer with respect to in-game graphics. The closest that comes to

mind would be Final Fantasy 13 (FFXII). While Crysis stunned people with its geographical

marvels, FFXIII excelled in very detailed and realistic character design.

And while the growth of 3D modeling industry has exploded in the last 20 years, we still see

more and more improvements being implemented. I find myself asking how much further

can we go? If we can achieve this level of design already using these programs, how much

more realistic will it be in another 20 years? This is already become a norm in society and is

used greatly in the all commercials we take for granted. We see it in television, movies,

music videos, video games, and all other sorts of media. As to how far it eventually goes, I


have no idea, but the pattern so far shows that it has come far and is not going to stop for

anyone.

- Medicine

The study of medicine is always changing; advancements in procedures to help those

who are in need are being introduced regularly. Within the last 100 years, new procedures have

allowed us to see patients bones (x-ray discovered 1895), view lymphatic nodes, ultrasound,

and so much more. Thanks to these advances, medical practitioners can now get accurate scans

of patients and be able to generate 3D models, referred to as 3D imagining, of whatever was

scanned to help doctors examine issues with their patients. Unfortunately most of this

technology is reserved for extreme concerns such as intense bone fractures, problems with

internal organs, and other issues. A quote from the academic article, A Survey of Medical Image

Registration by J. B. Antoine Maintz and Max A. Viergever;

The imaging modalities employed can be divided into two global categories:

anatomical and functional. Anatomical modalities, i.e. depicting primarily morphology,

include X-ray, CT (computed tomography a), MRI (magnetic resonance imaging b), US

(ultrasound c), portal images and video sequences obtained by various catheter’

scopes’, e.g. by laparoscopy or laryngoscopy. (M&V)


For the purpose of this paper, we will focus on the anatomical modalities. The procedures

listed in the quote have 3 different spatial dimensions onto which the data can be viewed and

transcribed by the computer; 2D-2D, 3D-3D, and 2D-3D.

In the simplest terms that spatial dimensions can be described as follows:

Spatial (infrequently spelled spacial) dimensions are those which we normally associate with the characteristics of height, length, width. It would be correct to say that a cube has three equal spatial dimensions. The term dimension is used to refer to the size of something, so spatial dimension is the aspect of the physical extent, or spatial extend, of an object. One may also speak of other measurements of size … A person's age is a size in the time dimension. The universe is known to have three spatial dimensions and one time dimension … The concept of dimensions is not limited to space and time … The concept of size or extent, hence the concept of dimension, goes beyond physics and mathematics and one can, for example, speak of the color dimensions something may have.In short, a spatial dimension refers to physical size in one direction in space and there are three spatial dimensions

and one temporal dimension that are intrinsic to the universe in which we live. (Answers.com)

I will try to ‘translate’ what I believe in much easier terms. In this world there are 3

spatial dimensions (2d-2d, 2d-3d,-3d-3d), from what I understand 2d-2d images are the

equivalent of a standard picture that you would find in a picture frame or what you would see

on TV or in a movie - a flat non popping out surface. 2d-3d is what I believe would be

considered what you would see in movies and TV, things that are really flat but with

technology, whether it be special glasses or whatever, it projects a 3d image to the human

brain. And as for 3d-3d this is where the image would actually have to be projected in a way


where it can be viewed in a manner where the user could move around it and see it in multiple

angles and views.

At the current stage, 3D imaging is used more in a study-based case instead of what can

be called action-oriented case into where the technology is issued on the spot. One of the lead

areas of 3D imaging is Stanford’s department of radiology, sub department 3D Radiology.

“Using the 3D imaging lab has allowed us in pediatric urology to identify and assess renal

scarring and damage that has not been recognized by any other imaging means, and has

changed my management and thinking about children with vesicoureteral reflux.” (SF1)

Thanks to many universities, like Stanford, achievements in 3D imaging have allowed

practitioners to be able to apply 3D imaging to the following

Surgery (general, vascular, cardiothoracic, neuro, plastic, and orthopedics) Pulmonology Gastroenterology Cardiology Urology/Nephrology Pediatrics Medicine Neurology Emergency/Trauma

(SF2)

- Academics

The study of 3D modeling in academics is still relatively new but has been steadily

growing over the years. 3D modeling application in academia started off by the use of awful

looking (self opinion) instructional videos and it wasn’t till the commercial industry started to


use 3D effects that students took more of an interest in the topic. Today you can apply to

schools dedicated strictly to the subject, such as Full Sail University. Full Sail is a pure

multimedia college located in Winter Park, Florida. The reason I chose to discuss this university

instead of others is because of the number of the distinguished achievements that their alumni

have made as a result of their education. One grad is has been nominated for an award for

doing the special effects for Lady Gaga’s music video Bad Romance.

“We offer prospective 3D artists a complete program of study through a combination of fine

art and high technology,” says Bandstra, director of the computer animation and game art

programs. “When students emerge from Full Sail University, they will be 3D content developers

capable of creating content for the film, television, games, architecture, medical, and all

manner of other industries.”

3D modeling in schools has allowed freedom and creativity to flow freely within the

students who attends them, giving them the tools and power to innovate, impacting their own

lives and the work and lives of many others.

Another academic center with a focus on 3D modeling (commercially at least) is an

online school called The Game Institute. While focusing mainly on gaming they do offer courses

on Robotics, Physics Emulation in programs, AI Path-finding and much more. Even though this

school does not really have any significant “achievements”, it helps its students by using

working professionals in their faculty who have practical experience working in industries that

use 3D modeling. I personally can vouch for the method and have been happy with their

lessons on programming and do wish to do their 3D modeling course one day. Due to the fact


that it is online, students can take as long as they need to complete the work and once finished

they can go to a specific testing location to take a true paper final to get college credits. (…)

- Scientific

3D modeling in the field of science has greatly increased the ability with which scientists can

create accurate recreations of they are studying. A short article from NASA shows how they

used 3D modeling to recreate the landscape of Mars by using the Mars Reconnaissance Orbiter

to gather data. NASA used this data to recreate the terrain. The image is a bit exaggerated due

to the lack of complete and accurate data.

Such digital terrain models are superior to standard stereo images viewed with

blue-red glasses, which show only relative changes in elevation instead of absolute

numerical data. Digital terrain models can be used for rendering perspective views from

any angle or even fly-by movies. More importantly, they can be used for detailed

quantitative analysis, such as profiles, slopes, morphometry, numeric modeling, etc.

(NASA1)

Another person thought up of a very similar idea using both a combination of 3D

modeling, aerial photography, and GIS to be able to create accurate and detailed scenes of

cities and rural areas.

3D urban models provide a better visual representation of urban space and

urban features than 2D maps (Ranzinger and Gleixner 1995). The importance of 3D

urban models with multiple levels of detail has been evidenced by a wide range of

applications, such as urban planning, architecture, navigation, public safety studies,

http://www.nasa.gov/mission_pages/MRO/multimedia/pia12840.html


transmitter placement for telecommunication, and flight simulation.”(GIS-BASED 3D

URBAN MODEL1)

WEI-MING, LIN, the author of the article, CONSTRUCTING A GIS-BASED 3D URBAN

MODEL USING LIDAR AND AERIAL PHOTOGRAPHS, and the quote above, believes that with

his hypothesis of using 2 different data gathering sources and importing it into a 3D generating

program we will be able to gain highly detailed models onto which people of all fields of work

will be able to use. Wei-Ming also goes into greater detail of the multiple tools which he wishes

to try to combine.

The panoramic imaging method allows the user to look around an urban scene

with a full 360° view… Virtual reality modeling language (VRML) is a computer language

that can be used as a framework to create a virtual 3D view for a small urban

scene… The computer-aided design (CAD) technique is a very sophisticated and

powerful tool. CAD technique has strong capabilities in storing and managing large

amounts of geometric information about urban objects, and it is an efficient tool for

designing and creating urban objects. (GIS-BASED 3D URBAN MODEL2)
