Cone Texture Mapping

[Jon Prime]

I'm trying to use pre3d to draw a cone with a texture mapped to it. I have the geometry working/rendering OK, but now I'm trying to get a texture mapped to the triangles that make up the sides of the cone.  I was hoping that there was just a way to set the uv in the textures for each slice such that the top (point) part of the images would be scaled down but that did not seem to work. Any recommendation how to go about this?

Thanks
