Imagine bisecting a parallelogram about the diagonal to form two equilateral triangles.

...
GL_TRIANGLE_FAN :
v1 v2 v3 v4 v5 v6 -> (v1 v2 v3) (v1 v2 v4) (v1 v2 v5) (v1 v2 v6)
...

Wouldn''t that be
GL_TRIANGLE_FAN :
v1 v2 v3 v4 v5 v6 -> (v1 v2 v3) (v1 v3 v4) (v1 v4 v5) (v1 v5 v6)

I am pretty sure that this one is correct. It doesn''t keep the 2nd vertex to all the other ones it keeps the first vertex.

like this to make a circle

  glBegin(GL_TRIANGLE_FAN);   glVertex3f(0,0,0);   for (float c=0; c<=PI; c+=PI/20)      glVertex3f(cos(PI),sin(PI),0);glEnd();

that would make a Circle with 20 polys.
