overlay a 3D polygon on a 2D grayscale image? [message #31871]

Hi,there,

I have a 3D polygon and a 2D grayscale image. I am trying to overlay the
polygon on the 2D image, so I can see the image through the
semi-transparent polygon. Also, I am NOT intending to use the 2D image as
a texture map.
I know David Fanning's website has an example of blending two 2D image
together using alpha channel. I tryied to make the 2D image transparent (
which is not what exactly I want), so I can see the polygon, but seems
like it won't work that way.
Appreciate any help....
