Appendix A: OpenGL and IRIS GL
The first step in porting a RealityEngine IRIS GL application to OpenGL is to consult the OpenGL Porting Guide. It covers all the core IRIS GL and OpenGL functionality, window and event handling, and OpenGL extensions up to and including those in IRIX 5.3.
This appendix provides some additional information about porting IRIS GL to OpenGL, pointing to the extensions discussed in earlier chapters of this book where appropriate. In order to make it as short and comprehensible as possible, it won't repeat any information from the OpenGL Porting Guide.
