Thanks for that, but it doesn't seem to work. Well, it gives coordinates
of x,y(,z) but when the camera changes angle (but not position), the
coordinates don't change. What else do I need to be doing in this?
Anyway, I also forgot to mention this is how I make the text images:
def __init__(self):
pygame.font.init()
self.font = pygame.font.Font(FONT,18)
self.char = []
for c in range(256):
self.char.append(self.CreateCharacter(chr(c)))
self.char = tuple(self.char)
def CreateCharacter(self,s):
try:
letter_render = self.font.render(s,1,(255,255,255), (0,0,0))
letter = pygame.image.tostring(letter_render,'RGBA',1)
letter_w,letter_h = letter_render.get_size()
except:
letter = None
letter_w = letter_h= 0
return (letter,letter_w,letter_h)
Since I make the text this way, I'm thinking of just doing it billboard
but I'm not sure how to implement half of this.
Thanks again for any help.
Cheers

Er, the last three arguments return the data in C. In Python, the
syntax is different:
C: gluProject(objx,objy,objz,model,proj,view,winx,winy,winz)
Python: winx,winy,winz = gluProject(objx,objy,objz,model,proj)
And yes, it returns a z-coord, which should take into account the near
clipping plane. As long as the plane is ~0, (x,y) should be fairly
accurate.
Keep in mind that the (x,y) coordinates are *real* coordinates, (i.e.,
the y is not flipped). (0,0) is the bottom left. If you rasterize
the font as you were, it shouldn't be a problem.
