Hi there,

You need to run:

glEnable(GL_BLEND);

You should also specify the way OpenGL will perform the blending:

Try:

glBlendFunc(GL_SRC_COLOR, GL_ONE);
 or
glBlendFunc(GL_SRC_ALPHA, GL_ONE);

Your ALPHA value in glColor4f will specify how Opaque your poly is.
0.0fwill be invisible and
1.0f will not be transparent.  There are lots of different options for
glBlendFunc that act differently.  Also, having lighting enabled will affect
how the blending interprets your alpha values.

Regards
Richard
