Obj files support higher-order surfaces using several different kinds of interpolation, such as Taylor and B-splines, although support for those features in third party file readers is far from universal. Obj files also do not support mesh hierarchies or any kind of animation or deformation, such as vertex skinning or mesh morphing.
The FBX can be represented on-disk as either binary or ASCII data; its SDK supports reading and writing both. While neither of the formats is documented, the ASCII format is a tree structured document with clearly named identifiers. For the FBX binary file format, the Blender Foundation published an unofficial specification, as well as a higher level unofficial spec (work in progress) for how ...

Additive manufacturing file format (AMF) is an open standard for describing objects for additive manufacturing processes such as 3D printing.The official ISO/ASTM 52915:2016 [1] [2] standard is an XML-based format designed to allow any computer-aided design software to describe the shape and composition of any 3D object to be fabricated on any 3D printer via a computer-aided manufacturing ...
Wings 3D is a free and open-source subdivision modeler inspired by Nendo and Mirai from Izware. Wings 3D is named after the winged-edge data structure it uses internally to store coordinate and adjacency data, and is commonly referred to by its users simply as Wings.
COLLADA (for 'collaborative design activity') is an interchange file format for interactive 3D applications. It is managed by the nonprofit technology consortium, the Khronos Group, and has been adopted by ISO as a publicly available specification, ISO/PAS 17506.
The image is called a UV texture map. [1] The UV mapping process involves assigning pixels in the image to surface mappings on the polygon, usually done by "programmatically" copying a triangular piece of the image map and pasting it onto a triangle on the object. [2]
[1] [2] [3] Three-dimensional (3D) models represent a physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. [4] Being a collection of data (points and other information), 3D models can be created manually, algorithmically (procedural modeling), or by scanning.
