Would it be possible to render a quad that is completly transparent? Invisible? If so how, I need to make hidden spots that you can''t see that you can click on for special power ups. Thanks Matt

Sure, just draw it in a colour that has an alpha component of zero:

glColor4f(0.0f, 0.0f, 0.0f, 0.0f);
