Table A-1 contains a list of equivalent calls that you might find useful while porting. The first column is an alphabetical list of IRIS GL calls, the second column contains the corresponding calls to use with OpenGL, and the third column contains pointers to any relevant discussion in the text.
 | Note: In many cases the OpenGL commands listed will function somewhat differently from the IRIS GL commands, and the parameters may be different as well. |
Be sure to refer to the OpenGL reference pages in the OpenGL Reference Manual for detailed descriptions of the functions of the these commands and the parameters they take.
You might also need to refer to X or IRIS IM documentation; some appropriate X and IRIS IM manuals are listed in “Where to Get More Information”.
