ns2m
Draw a marker
Prototype
void ns2m(int type, float size, float x, float y, float z, float red, float green, float blue);
Description
Draw a marker at (x,y,z) with size and RGB colour (red,green,blue). Argument type should be one of:
- 0 = tetrahedron (pyramid)
- 1 = wireframe 3D cross
- 2 = shaded box
- 3 = octahedron (diamond)

Code Example
#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"
int main(int argc, char *argv[])
{
int i;
int marker; /* Type of marker to use */
float x, y, z; /* Position */
float r, g, b; /* Colour */
float size = 0.4; /* Size of marker */
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 */
marker = 0;
for (i=0;i<4;i++) {
x = drand48()*2.0 - 1.0; /* Random position */
y = drand48()*2.0 - 1.0;
z = drand48()*2.0 - 1.0;
r = drand48(); /* Randomish colour */
g = 1.0;
b = 0.3;
ns2m(marker, size, x,y,z, r,g,b); /* Draw the marker */
marker = (marker+1)%4;
}
s2show(1); /* Open the s2plot window */
return 1;
}
