    You have to turn on blending, I think.

    maybe something like this:

    glEnable(GL_BLEND);
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
    glEnable(GL_DEPTH_TEST);

    But with blended trinagles you should proceed the following:

    1. draw all non-transparent primitives
    2. code above
    3. draw your transparent primitives depth-sorted(furthest first, nearest last)

    if primitives are texture-mapped or not doesn't matter.
