.IGS File Extension
File Type 1Indigo Renderer Scene File
|Category||3D Image Files|
File format categories include Binary, Text, XML, and Zip. The format of this file type has not been determined.
3D scene used by Indigo Renderer, an application used for generating photorealistic images; often saved as an export from another 3D modeling package that has the Indigo Renderer plug-in, including Blender, 3ds Max, Cinema 4D, Maya, SketchUp, or Revit.
Once a 3D scene has been imported into Indigo Renderer, it can be rendered into a final image. The software supports GPU acceleration so that images can be generated more quickly.
File Type 2IGES Drawing File
2D/3D vector graphics format based on the Initial Graphics Exchange Specification (IGES); used by many CAD programs as a standard ASCII text-based format for saving and exporting vector data; can store wireframe models, surface or solid object representations, circuit diagrams, and other objects.
The IGES format was introduced in 1979 and became the standard for transferring three-dimensional models between CAD programs. In recent years, however, it has been replaced by the newer .STP format.
