This appendix lists IRIS GL functions and their equivalent OpenGL functions. The first column is an alphabetic list of IRIS GL functions, the second column contains the corresponding functions to use in OpenGL.
Note The following OpenGL functions listed may behave somewhat differently from the IRIS GL commands, and the parameters may be different as well. For more information on the differences between IRIS GL and OpenGL, see IRIS GL and OpenGL Differences.
