ss2tc

Enable/disable (1,0) camera translation.

Prototype

void ss2tc(int enabledisable);

Description

Enable (enabledisable = 1) or disable (enabledisable = 0) camera translation. This is particularly useful in fisheye display modes.

ss2sc Set the camera position, up vector and view direction.
ss2qc Query the camera position, up vector and view direction.
ss2sas Start/Stop the camera rotation.


Code Example

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

int main(int argc, char *argv[])
{
   int i, N = 20;                               /* Loop variables */
   float x, y, z;                               /* Random data */
   int trans = 0;                               /* Translation disabled */

   srand48((long)time(NULL));                   /* Seed random numbers */
   s2opend("/?",argc, argv);                    /* Open the display */
   s2swin(-1.,1., -1.,1., -1.,1.);              /* Set the window coordinates */
   s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0);  /* Draw coordinate box */

   s2slw(3);                                    /* Set line width */
   for (i=0;i<N;i++) {
      x = drand48()*2.0 - 1.0;                  /* Random (x,y,z) */
      y = drand48()*2.0 - 1.0;
      z = drand48()*2.0 - 1.0;
      s2sci(15*drand48() + 1);                  /* Random colour */
      s2pt1(x,y,z,1);                           /* Plot the point */
   }

   ss2tc(trans);                                /* Set translation state */
   s2sch(0.8);                                  /* Set text height */
   s2textxy(-1,0,0,"You can't translate camera with +/-!");

   s2show(1);                                   /* Open the s2plot window */

   return 1;
}
