3D Image File Types
3D image files include three-dimensional models, 3D animations, and 3D project files. 3D models are typically comprised of polygons and verticies and that create the model's shape. They may also include textures as well as lighting and shading information.
Common 3D image file extensions include .OBJ, .IGS, and .MA files.
Other image file categories include Raster Graphic and Vector Graphic files.
