Prototype

void s2svp(float x1, float x2, float y1, float y2, float z1, float z2);

Description

Set up the region of 3D space that is used for plotting. This is the "viewport" where graphics are drawn. The default values are [-1,+1] for all coordinates. A "fatal" error will occur if x1 > x2 or y1 > y2 or z1 > z2.

   s2svp(-1.,0., -1.,1., -1.,1.);		/* First view port */
   s2swin(-1.,1., -1.,1., -1.,1.);		/* Set the window coordinates */
   s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0);	/* Draw coordinate box */

   s2sci(S2_PG_RED);
   s2svp(0.5,1., -1.,1., -1.,1.);		/* Second viewport */
   s2swin(-1.,1., -1.,1., -1.,1.);		/* Set the window coordinates */
   s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0);	/* Draw coordinate box */
   
   s2show(1);					/* Open the s2plot window */
