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.
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.
Other application types, such as CAD/CAM tools, usually need to convert the mesh data into a custom mesh format for more efficient data handling. OpenCTM uses a triangle index array to represent the triangle connectivity information , and several arrays for representing vertex data (vertex coordinates, normals , UV coordinates and custom vertex ...
CloudCompare is a 3D point cloud processing software (such as those obtained with a laser scanner).It can also handle triangular meshes and calibrated images. Originally created during a collaboration between Telecom ParisTech and the R&D division of EDF, the CloudCompare project began in 2003 with the PhD of Daniel Girardeau-Montaut on Change detection on 3D geometric data.

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 ...
Art of Illusion is 3D graphics software, [2] such as Blender and Wings 3D (which are both free software), and Autodesk 3ds Max and Autodesk Maya (which are both proprietary software). Although some sources seem to confuse 3D modeling with computer-aided design (CAD) , [ 5 ] Art of Illusion does not provide any CAD-like features, such as ...
One way is for the 3D modeller to unfold the triangle mesh at the seams, automatically laying out the triangles on a flat page. If the mesh is a UV sphere, for example, the modeller might transform it into an equirectangular projection. Once the model is unwrapped, the artist can paint a texture on each triangle individually, using the ...
