Hi, I'm trying to output a value which a variable is carrying, in to my graphics. Here is how I'm trying to do it:
void *font = GLUT_BITMAP_9_BY_15;
char s[100];

void outputCharacter(float x, float y, float z, char *string) 
  int len, i;
  glRasterPos3f(x, y, z);
  len = (int) strlen(string);
  for (i = 0; i < len; i++) 
    glutBitmapCharacter(font, string);

void RenderScene(void)
	sprintf_s(s,"%d", disp);
outputCharacter(- ((gridspace * n)/2-(gridspace/2)) - 42, (gridspace * n)/2-(gridspace/2) - 9, 0, s);

				// Restore transformations

				// Flush drawing commands



Obviously this is just bits and bits and you won't be able to compile it. The variable which carries the value that I want is called 'disp'. It is a big number (a pressure value up to 500,000 Pa). But it will just display a zero at the momment. I double checked to see that disp is carrying the correct value of 500 Kpa.
