The approximation gets better as the triangles get smaller. You can read much more about animation techniques and encodings in this Bachelor thesis by Marcus Lundgren. It also supports skeletal animations and morphs.

Standards of the Khronos Group. You can take a look at it when you need to make a decision. Film industry, video game industry.
In this encoding, the surface of a 3D model is first 33d with a mesh of tiny imaginary polygons. For more information on the OBJ file format, you can see its Wikipedia page. The camera and light attributes can also be ignored since it is expected that the end users will change the camera position anyway as they navigate around a scene. In 3D printing, high precision is not a requirement because the current printers cannot print beyond a certain resolution.
However, since this format retains only ffiles most basic information about the 3D model, it cannot be used in situations where one does not want to lose information. In addition, most software also support reading and writing to a subset of proprietary formats that are so popular that they cannot be ignored.
Animation Some 3D file formats have the capability to store animations of a 3D model. Barnes,  it has since become the property of the Khronos Groupa member-funded industry consortium, which now shares the copyright with Sony. In addition, a surface can have a specular component indicating the color and intensity of true mirror reflections of light sources and other nearby surfaces. Scene information such camera position, lights can also be stored, but the format does not support directional light sources.
If you are looking for information about a certain 3D file format, you can skip the others and jump right to that 3D file format. Some 3D file formats have the capability to encode information about lights, as shown in this image.

A 3D model of a pigeon which contains color information, light sources notice the shadow and animations The basic purpose of a 3D file format is to store information about 3D models as plain text or binary data. Hence this is an approximate format. The basic purpose of a 3D file format is to store information about 3D models as plain text or binary data.
It was developed in the mid-seventies by the US Collaea Force. COLLADA defines an open standard XML schema for exchanging digital assets among various graphics software applications that might otherwise store their assets in incompatible file formats.
When rendering the 3D model, every surface point is assigned a coordinate in this 2-dimensional image. However, due to the complexity and size of the original standard, it has been later broken down into smaller, modular specifications in four major releases. It has been succeeded by X3D. In the discipline of high precision engineering such as aerospace engineering, the 3D models need to be smooth and precise at any scale.

The scene of a 3D model includes the position of light sources, cameras, and peripheral objects. It supports all features of the VRML format along with some additions.
The second important feature of 3D file formats is the ability to store appearance related information. Since STL is an approximate format, it needs very small triangular facets to reach this resolution, producing huge and unwieldy files in the process.
We wrapped up with a discussion of the 8 most important 3D file formats, focusing on their features, popularity and use cases.
