What is a SGI file?
SGI (or RGB) is the native raster graphics file format for Silicon Graphics workstations. It supports 8 to 32 bits of color depth and is often used in 3D texture mapping.
Although Silicon Graphics machines are rare today, the format persists in legacy 3D applications. Our Online SGI Viewer makes it easy to view these files on modern devices.
