s2swin

Set up the world coordinate range for the device.

Prototype

void s2swin(float x1, float x2, float y1, float y2, float z1, float z2);

Description

Set up the world coordinate range for the device. This configures the mapping of the user's coordinates to the device coordinates. x1, x2 define the range of the X-axis; y1, y2 the Y-axis, and z1, z2 the Z-axis. We use a standard right-handed coordinate system with X negative to left, positive to right; Y negative out of the screen, positive into the screen; and Z negative down, positive up. A "fatal" error will occur if x1 > x2, or y1 > y2, or z1 > z2.

   s2swin(-5.,5., -3.,3., -1.,1.);		/* Set the window coordinates */
   s2box("BCDETMNO",0,0,"BCDETMNO",0,0,"BCDETMNO",0,0);	
						/* Draw coordinate box */
   s2show(1);					/* Open the s2plot window */
