[PyOpenGL-Users] opaque polygons

[Astan C. <st...@al...>]

Hi,
Im trying to make this:

    green = (( 0.0, 1.0, 0.0, 1 ))
    glColor4f( 0, 1, 0, .1 )
    glBegin( GL_POLYGON )
    glMaterialfv( GL_FRONT, GL_EMISSION, green )
    rad = 0.5
    for i in xrange(0,360,5):
        glVertex3f(x1+math.sin(i*math.pi/180.0)*rad , 
y1+math.cos(i*math.pi/180.0)*rad,z1)      
    glEnd( )

 to be opaque. I read that the last part of glColor4f() allows alpha 
channels for transparency levels. I changed it and it still remains 
solid. What am I doing wrong?
Thanks again for any help.
Cheers
Astan
