kristian,
in general i would avoid mixing glut with performer but hadn't had a chance to test the both together.
glut must be initialized by calling glutInit():
NAME glutInit - initialize the GLUT library.
SYNTAX void glutInit(int *argcp, char **argv);
ARGUMENTS argcp A pointer to the program's unmodified argc variable from main. Upon return, the value pointed to by argcp will be updated, because glutInit extracts any command line options intended for the GLUT library.
argv The program's unmodified argv variable from main. Like argcp, the data for argv will be updated because glutInit extracts any command line options understood by the GLUT library.
DESCRIPTION glutInit will initialize the GLUT library and negotiate a session with the window system. During this process, glutInit may cause the termination of the GLUT program with an error message to the user if GLUT cannot be properly initialized. Examples of this situation include the failure to connect to the window system, the lack of window system support for OpenGL, and invalid command line options.
glutInit also processes command line options, but the specific options parse are window system dependent.
if you want to get any events for some device you have to make sure this device has been properly initialized _and_ you have to register a callback function (glutDeviceGet (GLUT_HAS_SPACEBALL), glutSpaceballMotionFunc ()).
just try it.
j.
p.s: as ov version 3.2 (i think) you _must_ register an display callback function. without doing this glut will exiting. this could be a problem when trying to initialize performer rendering too in the same application.
