3D modeling is the process of developing a representation of an object in the form of a 3-dimensional object. On a similar end, 3D simulation modeling is creating and analyzing a a digital design of a physical model of an object. 3D modeling and stimulation would be appropriate regarding a questions that focus on the effectiveness of 3D modeling on the preservation of historic artifacts and places around the world significant to the history of humankind.
Manual modeling would be appropriate for sculptures that want to replicate a piece of work or any object, in fact. This is more hands on work, getting your hands dirty. If the person is an artist, it would make sense for them to use manual modeling as it would favor their artistic designs and creativity. Procedural modeling would be most appropriate if a person is trying to replicate a plane, landscapes, or architecture. This is used in scenarios where it is more difficult to 3D models using basic 3D modeling software. Procedural modeling uses a set of rules to create its 3D models. A 3D model scanner analyses a real world object or environment by creating “point clouds” of data of the object’s or environment’s shape and/or color. This is pretty useful in modeling larger architecture as well as environments around the world. Photogrammetry uses pictures/photos to make measurements to get positions of the surface points of whatever photos were taken. With all of these techniques of modeling objects into a 3D form, this allows us to make visual representations of humanity and stimulate humanity and how humanity would function in many different scenarios in the the near future.
There was no readings for this week on the Moodle based on my knowledge, but I can add a few comments to the DH project we are working in as a class. Through the use of 3D modeling we are able to create architecture from the past and make a 3D representation of the of the city of Northfield during the Northfield Bank Robbery. We can create the various buildings present at the time. Nonetheless, there are some limitations to 3D modeling as well. Our representations cannot be 100% accurate due to the cost of using other modes of 3D modeling. We can use what we can get and get a fair amount of accuracy, but accuracy is definitely an issue in the project.
Yes, accuracy is indeed an issue in our Northfield 3D modeling. For example, I could not get any image that shows my building, the Lyceum Building, from any other angle but the front. Even when I visited the site, I could still not access those missing angles because of fences and other buildings surrounding it–which is quite annoying when you want a good accuracy for your model.
