this trophy madel created in blender though they are not exactly the same. The term 3D model refers to the object, while the 3D file refers to the object as well as the corresponding file type. For instance, a Solidworks file and an STL file are both 3D files and can represent the same 3D object/moel. There are a two major representations of 3D models. A solid model defines the volume of the object that they represent. Solid models are useful for engineering simulations such has load analysis or heat heat transfer analysis. A surface model represents the surface of an object, like a shell. Surface models are useful for communicating model appearance and are common in video games and film.
It is a polygonal mesh defined by vertices and normal vectors that represent the surface features of the 3D model. The volume enclosed by the water-tight polygonal surface mesh contains no information.Blend files can be exported by almost any 3D modeling software.
