Welcome to the realm of complex numbers!
Change-log for MathMod-11.1 (16/06/2021)
1) Support of graphing functions with complex numbers Z=u+iv in 3D and 4D spaces (demo scripts: "Complex3D_xx" and "Complex4D_Saddle")
2) Added support for HSV (hue, saturation, brightness) coloring model (script: "Complex_Domain_Coloring")
3) Texture definitions (RGB and HSV) for parametric surfaces can now be expressed as functions of complex numbers
4) Added a software implementation for the OpenGL variable gl_FrontFacing (fixed an issue with GPU drivers on MacOSX Catalina).

TPlot is a component for Borland Delphi, Kylix and BC++ Builder to graph and manipulate sets of real X/Y (and Z) data, and to do all the usual GUI things such as file opening and saving, printing, copying, and saving in different image formats.
A program to calculate and represent the Mandelbrot set
...The user disposes of a graphical interface to control the program and modify conveniently some parameters, like the XY-scales, the XY map area, the Julia seed for the complex series
iteration of Z(n+1)=Z(n)^2+a, being Z(0)=(X0,Y0) the seed, and
"a in XY" the points to be calculated.
The user can enter (among other parameters) the desired convergence-radius R for the series, and/or the number of maximal iterations N for the generator-equation in Z.
2D and 3D contour and colour map of regular or scattered data
...There is a good example with the topographic data of Poland with 5902 data points to introduce yourself how to use it. There is not much documentation but it is easy to use. The input data are in XYZ format, where Z is a function of XY of the form Z=F(X,Y). The data file is in plain text format.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
Project is intended to plot 2D colour maps using 3D data, set of X, Y, Z numbers in 3 columns of data file. The data are assumed scattered, experimental points. The Z coordinate coded as colour.
FRIDA (flexible rapid interactive data analysis) is a generic program for manipulating, fitting, and plotting x,z,y data. It is primarily aimed at spectral analysis, especially in neutron scattering. Note: project has moved away from sf.net.
Ray aims to be a full-featured extensible raytracer portable among POSIX and Windows with native support for multi-threading and network distribution. It will provide a scene programming langage with a VM [more features to be added once available].
NOTE: Use Fltk_Contour insted this code! FMesh is a simply scientific data visualization tool based on OpenGL. FMesh can generate 2D and 3D graph of contour and color maps for any (x,y,z) scattered data set, many other options are included.
NrdbView is GIS (Geographic Information System) for displaying and editing of spatial data stored in .shp shapefiles( M, Z and Multipatch). NRDB View Use FreeImage lib to display georeferenced images. Actually MFC c++ but working on WxWidget migrating.
