Real-Time Evaluation

The Quick Eval option offers the means to evaluate a few basic properties of a surface in real time as algorithms and settings are changed. Simply enter an X and Y value in order to have a Z computed automatically with each change in the surface.

Since optimizations are such an important part of surface science, the Surface Min and Surface Max checkboxes allow for the display of the X,Y,Z coordinates of the minimum and maximum of the surface. These are found by a two dimensional minimization algorithm that seeks 1E-8 fractional precision. Note that the minimum and maximum computations may be slow with procedures that are inefficient with individual function evaluations.
