Support for SpaceNavigator in OpenGLUT and FreeGLUT

[mfalda]

I have added the support for SpaceNavigator in Linux OpenGLUT and FreeGLUT (see the Windows counterpart of this forum for the Windows version). You can find the precompiled libraries here:

OpenGLUT
FreeGLUT

I have sent the code to the FreeGLUT developers, in the hope that they will include it in future versions and they will add OSX support.

In practice, I have implemented two call-backs that were void in the original libraries:

Code: Select all

void glutSpaceballButtonFunc(int button, int state);

and

Code: Select all

void glutSpaceballMotionFunc(int tx, int ty, int tz, int rx, int ry, int rz);

In this way, you can write an application using a code as simple as:

Code: Select all

#include <GL>
#include <stdio>

void sbButton(int button, int state)
{
   printf("%d, %d\n", button, state);
}

void sbMotion(int tx, int ty, int tz, int rx, int ry, int rz)
{
   printf("%d, %d, %d, %d, %d, %d\n", tx, ty, tz, rx, ry, rz);
}

int main(int argc, char** argv)
{
   glutInit(&argc, argv);
   glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
   glutInitWindowSize (500, 500);
   glutInitWindowPosition (100, 100);
   glutCreateWindow (argv[0]);
   glutSpaceballButtonFunc (sbButton);
   glutSpaceballMotionFunc (sbMotion);
   glutMainLoop();
   return 0;
}
