Some popular formats available include FBX, STL, OBJ, glTF, and DAE among others. They are used in video games, 3D printing, engineering, movies and so much more. These are used to store the appearance of a model, encoding the model animations, encoding the geometry, and storing the physical appearance of the model. Examples that allow free downloads are Sketchfab and Google Poly among others. There are many sites with different 3D models. One can modify existing templates that are on the computer or were previously created for another project to suit your needs. This method is much simpler and more preferable, since one can use 2D images generated with a smartphone and obtain live 3D models. Photogrammetry can be simply defined as the art of acquiring reliable measurements from 2D images by overlapping them to form a 3D model. ![]() Photogrammetry is another process that one may use. You can create one by scanning the item with your scanner of choice. One may also design it online at 3D modeling sites. One may create 3D objects from scratch using 3D model creation software, which is downloadable into the computer. We are going to look briefly at each of the methods mentioned above. We can obtain 3D Objects by either creating one from scratch, scanning real-life objects, modifying templates to suit your need, and downloading online models. If this question is in your mind, we can easily answer it by saying that 3D objects or 3D models are shapes with three dimensions: length, width, and height. In our case, we will be using Visual Studio Code.
