SurGe is a computer program which enables to generate a surface as an interpolation (approximation) function of two independent variables; implements an interpolation / approximation method called ABOS which produces a surface comparable to a surface created by Kriging or Minimum curvature method.
approximation, neural networks, B-splines and parametric curves least squares approximations, plus a library of over 300 industry-specific 2D formulas. Built-in Wizard helps to apply different curve fits to discover the model that best describes the data. Last version includes the peak fitting features. The software enables you to smooth, interpolate, apply FFT and Wavelet filters, subtract, differentiate, integrate, and transform data and curves

A Low carb Calculator to find unlisted carbs based on a food products nurtrition label. It works by using the formula Calories = (Fat X 9) + (Carbohydrate X 4) + (Protein X 4) . Note that this formula is not perfectly exact, but an approximation. The program takes the difference between the stated calories and actual calories and divides by 4 to yield grams, and then adds that to the Carbohydrate grams listed on the label.
Aquatica engine can be used to simplify the implementation of water surfaces in application with DirectX9 graphics.
