3d Model Definition. 3d model and 3d file can be synonymous though they are not exactly the same. 3 d modeling is the use of software to create a virtual three dimensional model of some physical object.
This allows us to create a virtual model of how the object will behave in the real world even before it is ever built. A collection of vertices that form an object. The types of information included are geometric dimensioning and tolerancing component level materials assembly level bills of materials engineering configurations design intent etc.
A 3d model is a mathematical representation of something three dimensional.
Material weight size optical properties physical properties etc. Available in number of file formats including max obj fbx 3ds stl c4d blend ma mb. An artist uses special software to manipulate points in virtual space called vertices to form a mesh. A 3d model is the digital representation of a three dimensional object that is created in dedicated 3d modeling software.
