GLUT, the OpenGL Utility Toolkit, provides a programming interface for creating OpenGL applications. The GLUT3 file extension is associated with version 3.6 of this toolkit.
This is a software data file rather than a general-purpose document or 3D model. Its exact contents and role depend on the GLUT 3.6 installation or application that created it, and it is normally used by GLUT rather than edited manually.
GLUT 3.6 is legacy software, so the GLUT3 format is not commonly encountered in current OpenGL development.
Use the GLUT software for Microsoft Windows that is associated with the file. GLUT3 files are generally intended to be read by the toolkit or by an application that uses it, not opened as standalone documents.
If the file came with an older OpenGL program, keep it in the location expected by that program and start the program through its normal Windows shortcut or executable.
There is no standard conversion process for a GLUT3 file. It is an internal data file associated with GLUT 3.6, so it should normally remain in its original form and be used with the software that requires it.
