**stack pop.**Will get an image from the top of the Tina stack.**stack push.**Will push the displayed image back onto the Tina stack.**Grimson.**Will fill in the zero's of a sparse image assuming differential continuity and minimum elastic surface energy.**surface.**Will generate a projection of the current image surface in the*terrain*Tv according to the parameters in**Terrain Params**, which are;X interval Y interval Z scale Grimson iterations

It is advised that the X and Y parameters as set large initially until a good projection direction has been selected.
