The OSG file type is primarily associated with OpenSceneGraph.

OSG	File extension: OSG
	File type:	3D scene description file

What is an OSG file?

OSG files mostly belong to OpenSceneGraph. OSG files are used with OpenSceneGraph libraries to store 3D scene information in a plain text format.
This file type describes the structure of a scene by listing nodes, geometry, transformations, and texture data that a 3D engine later interprets to render a model or environment.

They are the core files used by OpenSceneGraph for scene building and simulation.

They are often saved as editable text, which makes it possible to change the scene manually.

A small number of OSG files are used as save files in some .NET applications.

How do you open OSG files?

You need a suitable software like OpenSceneGraph to open an OSG file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your OSG file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a OSG file directly in the browser:. Just drag the file onto this browser window and drop it.

OSG file format:

A file format defines how the data in the file is structured. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our examination of the OSG files comes to the following conclusion:

The OSG file extension is not widely used. Such a file is used by different programs with different formats. The two most common formats are as follows:

• 30% of all OSG files have the same signature 34 01. They consist of illegible, cryptic characters. The average file size is 17 KB with most files being between 5 KB and 41 KB in size. The file type was created recently.
• 25% of all OSG files are associated with Open Scenegraph scene. These files contain text and words, not binary data. The file size is in the range of 3 KB to 16 MB. The files contain the following words: Group {, cullingActive TRUE, name, nodeMask 0xffffffff, UniqueID, DataVariance, Geode { and num_children 1. avatar.osg or cow.osg is a typical file name.

The remaining 45% of all OSG files are files with no common format, such as OSG and MatrixTransform. Tagged as tile or hatchback. If you want to find out which format your OSG file belongs to, just click on the button "Choose your .osg file to analyze".
