OpenGL Performer was a Silicon Graphics (SGI) toolkit for developing real-time 3D graphics applications. The .glut2 file extension identifies data associated with its OpenGL GLUT 3.6 support.
It should be treated as an application-specific data file for the OpenGL Performer environment, which was available on multiple platforms.
Open a .glut2 file on a system with OpenGL Performer installed. Use the Performer tool or workflow that created the file; it is not normally intended to be opened directly in a text editor or a general-purpose graphics program.
OpenGL Performer was available on multiple platforms, but support depends on having a compatible legacy installation and the associated application files.
If conversion is required, open the file in a compatible OpenGL Performer environment and use an export function only if that version provides one.
