PARAMETERS

*p

list of coordinates of points to be drawn.

n

number of points to be drawn

attr

attributes (specifies the drawing method)

RETURN VALUE

FUNCTION

• Draws n points.
• An array of NJS_POINT2COL type is used when drawing multiple points. n points of the specified color are drawn at the points specified by p in the global coordinate system.
  

  NJD_DRAW_NORMAL	Normal drawing.
  NJD_TRANSPARENT	Transparent drawing.
  NJD_USE_TEXTURE	Drawing with texture.

  
  The following 3 attributes can be used for drawing. These attributes can be used in mutually consistent combinations by using the "|" character as a delimiter.

  EXAMPLE

  The following draws 100 points at random.

  int i;
  NJS_POINT3COL p;
  NJS_POINT3 point[100];
  NIS_COLOR  color[100];
  
  p->p = point;
  p->col = color;
  p->tex = NULL;
  p.num = 100;
  
  for(i = 0; i < 100; i++){
      p -> p[i].x = njRandom()*1000.f-500.f;
      p -> p[i].y = njRandom()*1000.f-500.f;
      p -> p[i].z = -njRandom()*1000.f;
      p -> col[i].argb.a = (Uint8)(0x80*njRandom());
      p -> col[i].argb.r = (Uint8)(0x80*njRandom());
      p -> col[i].argb.g = (Uint8)(0x80*njRandom());
      p -> col[i].argb.b = (Uint8)(0x80*njRandom());
  }
  
  njDrawPoint3D(&p, 100, NJD_DRAW_NORMAL|NJD_TRANSPARENT);
  

  

  Since this function draws in 3D, be sure to make appropriate view, screen, and matrix stack settings before calling this function.

  NOTES

  • The NJD_DRAW_NORMAL may be omitted when it is used in combination with other attributes.
