Is there a way to texture an polygon that has more than 4 vertexes using glTexCoord2f()?

Yep!

glBegin(GL_POLYGON);glTexCoord2f(0.5F + 0.5F * cos(2*PI/5*0), 0.5F + 0.5F * sin(2*PI/5*0)); glVertex(...);glTexCoord2f(0.5F + 0.5F * cos(2*PI/5*1), 0.5F + 0.5F * sin(2*PI/5*1)); glVertex(...);glTexCoord2f(0.5F + 0.5F * cos(2*PI/5*2), 0.5F + 0.5F * sin(2*PI/5*2)); glVertex(...);glTexCoord2f(0.5F + 0.5F * cos(2*PI/5*3), 0.5F + 0.5F * sin(2*PI/5*3)); glVertex(...);glTexCoord2f(0.5F + 0.5F * cos(2*PI/5*4), 0.5F + 0.5F * sin(2*PI/5*4)); glVertex(...);glEnd();

Yeesh!

I didn't get the math either

Take a look at this page on my website:

http://home.clara.net/paulyg/uv.htm

It shows one way of generating planar texture coords for arbitrary shaped surfaces.
