DipView [aspect=dip,azi]
 
DipView makes a relief shading from the dip and azimuth, useful for
visualisation of dips in grids. The aspect parameter determines the position
of the "light" in the resulting image.
 
Input:
0       Inline Dip (as angle)
1       Crossline Dip (as angle)
 
Output:
0       view
