Tested for GLX, but not WGL. * * Revision 1.9 2003/01/16 22:22:45 wes * Updated all source files to reflect new organization of header files: all * headers that were formerly located in include/rmaux, include/rmv and * include/rmi are now located in include/rm. * * Revision 1.8 2002/06/17 00:39:40 wes * Updated copyright line. * * Revision 1.7 2001/07/15 22:33:19 wes * Added rmPipeDelete to the end of all demo progs. For those that use * an initfunc, added a new RMnode * parm (which is unused, except for rm2screen). * * Revision 1.6 2001/06/03 19:44:05 wes * Add calls to new rmaux routines to handle window resize events, and * for keyboard event handling. * * Revision 1.5 2001/03/31 16:55:18 wes * Added procmode.h, which defines an RMpipe processing mode used in * most demonstration programs. The default processing mode is * RM_PIPE_MULTISTAGE_VIEW_PARALLEL. * * Revision 1.4 2000/12/02 17:24:32 wes * Version 1.4.0-alpha-1 checkin. See the RELEASENOTES file for * a summary of changes. With this checkin, these demo programs * are no longer compatible with versions of the OpenRM API that * are pre-1.4.0. * * Revision 1.3 2000/08/28 01:38:18 wes * Updated rmaux* interfaces - rmauxEventLoop now takes two additional * parameters (keypress and window resize app callbacks); replaced * rmauxUI with rmauxSetGeomTransform and, where appropriate, * rmauxSetCamera3DTransform. * * Revision 1.2 2000/04/20 18:04:34 wes * Minor tweaks and reorg for OpenRM 1.2.1. * * Revision 1.1 2000/03/13 02:40:18 wes * Initial entry. * */ #include <rm/rm.h> #include <rm/rmaux.h> #include "procmode.h" #define DEFAULT_ASPECT_MULTIPLIER .6 static RMnode *MyRoot;
