Code Example

#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"

void cb(double *t, int *kc)
{
   float qss = ss2qess();               /* Query current eye-separation */

   char string[32];                     
   sprintf(string,"Eye separation = %.2f",qss); /* Write to string */
   s2textxy(0,0,0,string);              /* Display text */

   float ess = (float)((*kc%10))/10.0;  /* Calculate new eye-separation */
   ss2sess(ess);                        /* Set the new eye-separation */
   
}

int main(int argc, char *argv[])
{
   fprintf(stderr,"Press the <spacebar> to change eye-separation");

   s2opend("/s2dsana", argc, argv);             /* Open in anaglyph mode */
   s2swin(-1.,1., -1.,1., -1.,1.);              /* Set the window coordinates */
   s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0);  /* Draw coordinate box */
   
   cs2scb(cb);                                  /* Install dynamic callback */
   s2show(1);                                   /* Open the s2plot window */

   return 1;
}
