ns2vspherex

Draw a textured sphere, with given centre, radius, colour and texture ID - vector input.

Prototype

void ns2vspherex(XYZ P, float r, COLOUR col, unsigned int textureid);

Description

Draw a textured sphere, with given centre, radius, colour and using a texture id as returned by s2extloadtexture. Uses vector data structures.

Code Example

#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"

int main(int argc, char *argv[])
{
   XYZ xyz = { 0.0, 0.0, 0.0 };			/* Position */
   COLOUR col = { 1.0, 1.0, 1.0 };		/* Colour */
   float radius;				/* Radius */
   char *texture = "firetile2_pow2_rgb.tga";
		/* Texture in directory pointed to by S2PLOT_TEXPATH */
   int texid;

   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 */

   radius = 0.4;

   texid = ss2lt(texture);			/* Load for later use */ 

   ns2vspherex(xyz, radius, col, texid);	/* Draw textured sphere */

   s2show(1);					/* Open the s2plot window */
   
   return 1;
}
