A Complete Advanced Graphics Solution
Developers take advantage of the power of Indigo2 graphics using an array of graphics libraries and development environments.
OpenGL is an industry-standard environment embraced by more than 30 companies. 2D, 3D, and imaging applications can be developed for a variety of hardware platforms with different operating and window systems. OpenGL includes operators for geometric and raster primitives, viewing and modeling transformations, as well as lighting, shading, blending, fog, hidden surface removal, texture mapping, and other graphics functions. These graphics functions are provided for every conforming OpenGL implementation, whether on a Silicon Graphics system, another vendor's workstation, or a PC. This makes applications written with OpenGL easily portable between platforms.
The IRIS Performer toolkit gives developers the means to achieve a fast, consistent frame rate for applications such as visual simulation, interactive entertainment, and simulation-based design. The IRIS Performer libraries are highly tuned for Indigo2 IMPACT, and build on the functionality of OpenGL and the IRIX operating system. With the intelligence to evaluate underlying hardware, IRIS Performer simplifies the management of the visual database, and renders scenes at maximum speeds on all Silicon Graphics workstations.
The ImageVision Library (IL) toolkit is an object-oriented extensible library for creating, processing, and displaying images. Its robust core set of image processing functions includes color conversion, arithmetic functions, radiometric and geometric transforms, statistics, spatial and non-spatial domain transforms, and edge, line, and spot detection. These functions simplify the extension of standard function sets to suit specific image processing needs.
