What is model geometry?

Model geometry refers to the physical shape and dimensions of a 3D model. It includes the size, proportions, angles, curves, and other physical properties that define the object's appearance and structure. Model geometry is crucial in computer-aided design (CAD), where accurate dimensions and shapes are necessary for precise engineering and manufacturing. In addition, model geometry is critical in computer graphics and visualization, where realistic rendering and animation require accurate representation of objects' geometry. Model geometry can be created from scratch using 3D modeling software, scanned from real-world objects using 3D scanners, or generated from CAD files in some cases. It is one of the fundamental aspects of 3D modeling and impacts the model's functionality, aesthetics, and usability.
