Z3=f(Z1,Z2) command (Generate menu)

This command generates a new 3D surface with amplitudes equal to the result of operating on the amplitudes of two existing surfaces. That operation might be subtraction, addition, multiplication, division, finding the arctangent of surface A divided by surface B, or finding the minimum or maximum amplitudes of those surfaces.

The command is disabled if there are not two or more 3D surface plots open.

Given two surfaces A and B, DPlot produces a new plot with the X and Y coordinates from surface A. Z values from surface B are obtained from the plane equation of the triangle bounding those X, Y values. If a given point is outside the extents of surface B (in other words if there is no triangle that bounds that point), then the point is discarded from the generated surface.
