Help : enlarge a triangle strip


I have a surface being represented as triangle strip.  The surface has certain view (glulookat API).  If I want to enlarge the surface/triangle strip, what should I do?  glscalef API does not work for me.  Not sure it is due to glulookat()

Thanks in advance


Are you sure your matrix mode is set to model view?

Sorry, setting to model view does not help. Should I use gluPerspective()?

In my experience, glscalef() on triangle_trip has the same effect as gltranslatef(), e.g. the triangle_trip is moved but is not enlarged. I have seen working example of glscalef() on glutwirecube().

The API used is glscalef(2.0f, 2.0f, 1.0f). Could it be the triangle_strip does not look larger because it is viewed from z-axis? If you have any other ideas, please let me know.
