3D modeling (or three-dimensional modeling) is the process of developing a mathematical representation of any surface of an object in three dimensions via specialized software. The product is called a 3D model.
Photo rendering is the 3D computer graphics process of automatically converting 3D wire frame models into 2D images on a computer. 3D renders may include photorealistic effects or non-photorealistic rendering.
Video rendering is the 3D computer graphics process of automatically converting 3D wire frame models into a animation video on a computer. Video renders may include realistic effects or non-realistic rendering.
