This Open-GL based utility allows exploring single or multiple grid(s) and performing the following data processing, the results of which can be stored
in an auto-generated worksheet for further analysis or graphing purposes. The functions include:
Subtracting a grid Z-values from another (e.g., generating a grid for an isopach map)
Subtracting a grid Z-values from a user-defined XY plane
Subtracting a user-defined XY plane from a grid Z-values
Multiplying a grid Z-values by a constant, e.g., converting the Z-values from feet to meter
Resampling the displayed grid by user-defined number of grid cells along the X and Y coordinates; e.g., for increasing resolution of a grid for
volume or area calculations.
