Gl_translate

allright correct me if im wrong but:

Code:

---

glTranslatef(3.0f, 0.0f, 0.0f);

---

will move the entry (?) point 3 units to the right on the x (seen from 0.0) no matter if you drew another GL_TRIANGLE on another place before that?

Yes....it will move 3 points from the origin (wherever that may be at the time).

You can draw in a place you have drawn before, but how it comes out depends on the z order and if you have any sort of blending set

so

Code:

---

glTranslatef(0.0f, 0.0f, 0.0f);

---

will always but the point in the middle of the screen as it were?

If the origin is set to the middle (because it will have no effect).....

[edit]
if you want to move to the middle, call glLoadIdentity()

ah i see now thanks !
