For this week’s lab, we performed 3D modeling of buildings on the Carleton College campus. I used Hunt House as my building that I performed my models on. Hunt House is one of the townhouse style housing options on the Carleton College campus, and can be selected for living through a group draw process. It includes its own kitchen, and also has a shared living room area for the residents that choose to live there. It is a space that allows a greater independent experience where students can choose the people they live with. The townhouse is also conveniently located near downtown Northfield, giving residents quick access to restaurants and small businesses nearby.
In terms of the modeling, in using Scaniverse, the process was much easier. I simply circled the townhouse using the Splat feature, and it gave me a pretty decent 3D model of the house as opposed to when I used Agisoft MetaShape (formerly PhotoScan) for my 3D model. This software was much more difficult for me because first I had to take many individual photos of all the different sides of the house to use for this program. I ended up taking what I believed to be a good 35 angles of the house, and when I uploaded them into the Agisoft software, in order to make the 3D model it needed to align the photos. However, the program found it incredibly difficult to align all of my photos and out of the 35 I took, only 8 were able to align no matter how hard I messed around with the software to try to increase this alignment. You can see this as only one side of Hunt House is portrayed. That being said, to answer some of the questions, building a model as opposed to simply viewing one through photographs or maps was incredibly different, and it made me realize just how difficult making these models can be. It has really made me appreciate how greatly models can aid visualizations, and how much work might be required in creating them. Additionally, this process of photogrammetry definitely does encourage close looking and attention to details you might have ignored. This is because in this process, creating these visualizations requires the precise inclusion of all parts of the house. If you forget even a little part, the alignments may not be able to work, or the collective scan might blank in some parts. That all being said, this lab was both fun, yet more challenging than I initially imagined.
Brandon, I totally agree with your reflection on the lab. I agree that it was definitely a challenge to work with the software and align the images due to the number of photos required. I ran into those same problems and learned that the continuity of the images is imperative in the success of this project. Yet, it was really cool to see that you had a fun time interacting with the lab material. It showed in your hard work, as you displayed Hunt House interactively!
I’m glad to read your reflection on both softwares: Scaniverse and MetaShape. I spent hours on that one with lots of difficulty. I didn’t try out Scaniverse but still wondered how that software compared to the other. Similarly to you, I had about 50+ images, but the software would not close to none of them no matter what I changed about the formatting. Eventually, I was able to have about 5 images align. I ended up with a similar looking model but with no detail.
