Function:ss2ssr
From S2PLOT
ss2ssr
Set sphere resolution.
Prototype
void ss2ssr(int res);
Description
Set sphere resolution. Spheres are drawn with (res*res) flat surfaces. Larger spheres (or spheres that will be viewed closer-up) require higher sphere resolutions. Be warned that rendering time takes a severe hit with resolutions much larger than about 12.

| ns2sphere | Draw a sphere, with a given centre, radius and colour. |
Code Example
#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"
int main(int argc, char *argv[])
{
float radius = 0.5; /* Radius of sphere */
int resolution = 32; /* Sphere resolution */
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 */
ss2ssr(resolution); /* Set the resolution */
ns2sphere(0.0, 0.0, 0.0, radius, 1.0, 1.0, 0.0);
/* A yellow sphere */
s2show(1); /* Open the s2plot window */
return 1;
