This is my attempt to develop an easy scientific data visualization widget for the FLTK library. I am developing and improving the code day to day. The widget is an OpenGL based contour visualizer for Linux, which allow you to built 2D and 3D graph of contour and colour map for a xy regular or scattered data set. There is a good example with the topographic data of Poland with 5902 data to introduce yourself how to use it. There is not documentation but it is easy to use.

The 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. So all what you need is something like this:

#     X                  Y              Z         ! You can add comments !

22.87500  54.12500  186.48
22.95833  54.12500  178.26
22.04167  54.04167  145.43
22.12500  54.04167  149.76
22.20833  54.04167  143.56
22.29167  54.04167  155.24
22.37500  54.04167  166.12
22.45833  54.04167  175.07

and so on... get the latest version using Git:

git clone https://github.com/eetorres/fltk_contour.git

Could not even compile it, neither in windows, not in linux. Tried fltk-1.1 & 2.0-CVS Compilers say lots of errors.

Sorry but, I can help you if you send me something about the error, maybe you can can attach a file with the error displayed by the compiler and send me it to eterresa@uis.edu.co

Hey friend, this library work well a least for me, try with Fltk relase 1.2 or 1.3 on WinXX with MSVC++ and tell if you have any error message.

I would really enjoy to compile it, but don't know what is FLTK 1.2 && 1.3 As far as I could understand you work under windows; as soon as I can get it compiled under win I could port it to linux (you look like to reject ANSI C standarts ;), since I need something similar. Maybe you could help me with some derections on how you compiled it?

I don't reject the ANSI C standard, the main problem is that I needed to use another widget to make the graph in order to port the Fl_Contour to Fltk and this one was only for Win. But now the widget is working with OpenGl so it is easy to port it to Linux which I would like to do but I have not had enough time to build the Linux makefile, but if  you want to do it, you should try to build it for the OpenGl test  only, gl_2d_test.cxx or gl_3d_test.cxx, don't try with fl_test.cxx. An then you will only need to add the other folders, like: MSMVTL, src, FL. Also you can find some data files into the directory /vc6/data. Best,  Edmanuel

It's very interesting, but could you pay attention to case in directory/file names ? "Fl" and "FL" or "Fl_draw.H" and "fl_draw.h" are not the same on non-Windows systems.

It would be nice if a makefile was put into the package so that Linux users could also build the program. At present it contains only a (Visual C specific) project file for a MS-Windows version.
