Calculations behind Surface Plots

I'm generating surface plots with my x, y and Z data. And MathCAD generates a surface from it. Reading through Help, I understand the following: 1. It generates a function from the given data (something like genfit()). 2. It plots the function over the data range (something like CreateMesh()). I'm looking for default function generated by MathCAD. Looking forward for responses. Thanks Vish

If the x, y, and z data are matrices (the preferred form) then the data is simply plotted as given, using the given points. If the x, y, and z data are vectors (to be avoided if at all possible) then Mathcad does an interpolation onto a regular grid. The form of this interpolation is not documented, and I don't know what it is.
