ns2text
Draw text at a given position, with right and up vectors, a specific colour, and a text string of course.
Prototype
void ns2text(float x, float y, float z, float rx, float ry, float rz,
float ux, float uy, float uz, float red, float green, float blue, char *text);
Description
Draw text at a given position (x,y,z), with right vector (rx,ry,rz) and up vector (ux,uy,uz), RGB colour (red,greeen,blue), and text string (text).

Code Example
#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"
int main(int argc, char *argv[])
{
float x = 0, /* Position */
y = 0,
z = 0;
float rx = 0.4, /* Right vector */
ry = 0.3,
rz = 0.2;
float ux = 0.2, /* Up vector */
uy = 0.8,
uz = -0.6;
float r = 1.0, /* Colour */
g = 0.0,
b = 0.4;
char *text = "S2PLOT is great!";
s2opend("/?",argc, argv); /* Open the display */
s2swin(-10.,10., -10.,10., -10.,10.); /* Set the window coordinates */
s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0); /* Draw coordinate box */
ns2text(x,y,z, rx,ry,rz, ux,uy,uz, r,g,b, text);
/* Display some text */
s2show(1); /* Open the s2plot window */
return 1;
