hi, friends

I have a 3D view with a polygon represent a data volume. I have put
three polygons with an image as a texture map. The image represent a
slice of the volume (i take the values of the position of slice in the
volume and make an image.

I'd like to make an image of slice data volume but:
1- The "points" with value different of 0 i want to see in the imge.
2- The "points" with value different of 0 i dont want to see, i want to
be transparents

Thanks.
