This document summarizes Angelea Langere's final project involving 3D modeling and scanning. It discusses how she used 123D Catch software to clean up and animate a 3D scan. It also details a scavenger hunt where she found 10 3D models online from various sites. The models ranged in quality and usefulness. Some provided detailed information that could help researchers and educators, while others lacked context or the ability to download the model. SketchFab was found to provide the most comprehensive models. The document examines the educational, research, and ethical considerations of the various 3D models.

Final Project

2. 1. 123D Catch
• The first part of this final project is to capture, create, and clean up a 3D
model using 123D Catch software. I started with an existing capture because
I ran into the same issues that I faced during exercise 1. I tried multiple
captures and followed all of the tutorial tips, including number of pictures,
even lighting, type of object, distance, and angles. After multiple failed
attempts with various items, I settled on using an existing capture from
exercise 1. However, I did start a completely new project, just with the
already existing capture.

3. These screenshots depict the multiple failed
processing attempts.

4. I started from the beginning of the only
successful capture I had.

5. I downloaded the model

6. Then, I opened the model in 123D Catch

7. I needed to use the “orbit” tool, to position my
model correctly on the screen.

8. After rotating the model, I needed to remove
the excess background, using the “polygon
selection” and the “rectangle selection” tools

9. I also needed to make sure to use the “orbit” tool to make
sure I deleted any background that wasn’t originally visible
to me. I missed much of the background during this step in
exercise 1

10. After using the tools provided, the model was
cleaned up and represented my original item.

11. After cleaning, I was able to make an animation
of the model using the “Animation Path”
button

12. After creating the animation path, it was time
to render the video.

13. After rendering the video, I was able to upload
it and share on YouTube

14. 2. Scavenger Hunt
• For the second part of the final project, I was able to find 10 different
models on different sites. These models vary in quality of capture as well as
content of data.

15. 1. Old Canon in Hong Kong
• This is a model that I found on Autodesk’s 123D models page. The only
information given is in the title “Old Canon in Hong Kong.” This model isn’t very
useful for any education applications because it doesn’t say what canon it is
supposed to be, what time period it’s from, or where the capture was taken. Without
this information it would be hard to conduct any research about the actual piece.
The quality of the piece is also somewhat low, without much detail on the actual
canon. Just from this model, it would require much work to form a watertight form
that would usable to 3D print. Also, once downloaded and opened in 123D Catch,
you can see that most of the pictures were taken above the piece rather than at
different angles, and this could cause problems when it comes to print.

17. 2. Alto Relieve
• This model was also found on 123 Catch’s models page. It appears to be a capture
of a sculpture, however there is no other information given. There is a tag on the
model for “Barcelona.” So, I would assume it’s in Spain. Without any other
information, anyone could assume that this a capture of the real piece, however, it
could be a capture of replica. There’s no way to tell from this model. The model
does appear to be cleaned well and of decent quality. With some work, I think this
model could be scaled down, made watertight, and 3D printed. The piece is one
color and judging from the capture, there’s not too many small tight details, so
various printers might be able to handle a small version of this piece.

19. 3. 1/1800 US CL Birmingham[1943]
• This model was found for purchase on Shapeways. It’s a model of a US
Navy ship during WWII. There’s no downloadable data on this product, but
rather an option to buy the already printed item. This model was found
under the “scaled models” section on the site, so the dimensions should be
accurate. However, there is no way to cross reference this information since
there’s no actual data given on it. A model such as this may be useful for
visual teaching purposes or may be intriguing to a collector of WWII or
Navy memorabilia.

21. 4. Bison Antiquus
• This model was found on the SketchFab website. This website provides
more data about the actual the model than other sites. The data on this
particular model is also available for download. This data could be very
useful for archeologists, students, or educators. The bison bones could be
compared to other bison from different areas and different times to
eventually make predictions about the similarities or differences among
different regions herding animals. Having this information could aid in the
research of many different fields.

23. 5. Chicanna, Mexico
• This is a model that was also found on SketchFab. It represents a palace in
the Rio Bec style, according to description. It’s a useful model, to some
knowledge of the landscape and some details of the building, however, there
is no downloadable data available for the model. Without this information,
the model is only useful for observable qualities, but this can still be useful
for people who are interested in architecture or history. The capture also
seems to be a low quality, with not very much attention to detail or even
more than a few sides of the building.

24. Chicanna, Mexico

25. 6. Astronomia
• This is another model from SketchFab. It depicts a sculpture of Astronomia from
the Royal Observatory in Greenwich, UK. It doesn’t have data available for
download either, however, it seems that the capture was of somewhat decent quality.
The downside to this model is that only captures one side of the sculpture, with the
back completely missing. This could be a result of the piece hanging on a wall or up
against flat surface. It would be difficult to study this piece without data or without
all surfaces of it being captured, but it may be of interest and use to an artist
looking to study different pieces or attempting to replicate pieces. There may be
some ethical considerations to consider if attempting to replicate an item including
whether or not this piece is protected under intellectual property rights.

27. 7. Mayan Statue
• This model was found on SketchFab and was captured by the same author as the
Bison Anitquus. The data and model are available for download, which is extremely
useful. This model depicts a Mayan statue. With this information available through
the internet, educators might be able to incorporate this into the classroom, giving
students a real life feel of a Mayan artifact without having to make a trip to the
museum. Museums across the world will also be able to use this information to
compare and contrast to different Mayan statues, aiding in the research process.
This kind of data is especially important when it pertains to an ancient people
because there’s not a large amount of information readily accessible. The capture
also looks to be high quality and is a complete 360 View. This may be able to be
watertight and able to be printed by various printers for either replicas or as small
scale novelty items.

29. 8. Two Acrobats
• This is a model of piece said to be by Mary Morse. The piece is called two
acrobats and was found on SketchFab. While the model is available for
download there are some ethical considerations for this piece. While the
description does mention the artist it doesn’t give any other information on
the piece or state whether or not the artist had given consent for this
information to be provided online. An artist may be concerned that someone
would replicate or change their piece to make it there own. Counterfeiting
could also be an issue here if the original is worth significant money.

31. 9. Leeds Library
• On Sketchfab, I was able to find a few different models of different places or
objects from Leeds Library. Having multiple items from one place can be extremely
useful for educational and research purposes. In both cases, “Leeds Library” may be
able to be studied as a whole if the models are put together to form a large 3D
model of the entire library. This would be extremely beneficial to researchers and
educators simply because the library could be studied in detail without having to
travel to the actual location. This allows for more time to be spent studying the
library, versus a traditional method of on site observation. These models,
unfortunately, aren’t available for download. I found the SketchFab website to be
the most cumulative as well the most user friendly site that I visited. I also found
much more quality models on this site than most of the other sites.

33. 10. Animaris Geneticus Gracilis Strandbeest
• The last piece I found was on Shapeways site, available for purchase. This
piece has no real application in education, except possibly the geometric
equations that may be done using this object. This piece is simply an art
piece, and one of many “Strandbeests” that this artist has created. It does,
however, exemplify the infinite possibilities for 3D printing. Artists are able
to create in ways that traditional technology never allowed for. This allows
for 100% personalized products that are completely customizable, and as this
technology progresses this will become more available to the average person.
