In our project, we mainly worked on creating a 3D model of our stepping stones through the usage of photogrammetry. To make a 3D model of an object, one needs to take photos from different angles and then use these photos to construct an image of the object. Through this process, photogrammetry allows one to look at the object from various angles. In this case, it enables us to view more of the object, which would not be possible using just one photo. The success of the technique will depend greatly on the images we will be starting out with.

As we created our 3D models of the stepping stones, it became apparent that the issue of how well an object can be recreated in its digital form is crucial. While we can create a model that resembles the actual object, it will inevitably lack some of its qualities. In our case, it will be impossible for the viewer to experience the actual weight, texture and feel of the stepping stones. The appearance of the objects will change depending on the viewer’s proximity. Although the model provides an opportunity to see the stones from different angles, it cannot fully reproduce the experience of seeing them. In addition, using the photos in the process allowed us to pay closer attention to the stones. It is possible to overlook the details and focus only on the general form of an object when observing it casually. However, while attempting to depict them in three-dimensional terms, it is easier to notice all those nuances. The irregularities of form and texture contribute to the unique appearance of each stone. The consideration of such details gave me an idea of how much information one may miss when not trying to depict something.

It was also very interesting to think about what we could do with the help of a digital model that was impossible to do with the original. It was possible to rotate the objects, observe them from different angles and pay attention to the separate elements. Thus, although the physical properties of the stones were lost in the process, the digital image gave another experience.

All in all, this assignment made us view the stepping stones differently. Initially, the assignment appeared quite simple: taking pictures of the object and converting it into a 3D model. However, it gave us a chance to look at this process from a different angle. Now we understand that there are many little details that distinguish our stones and that their conversion is quite problematic. Also, we have realized that modeling an object is not only about copying its form; it is about selecting its peculiarities and thus influencing the way others perceive this object.
