Hello. Inform, please, on what site it is possible to find materials on
construction of the three-dimensional graphic of function z=f(x,y) with the
help of Visual Basic .NET and GDI+?
Beforehand many thanks for your answer. Best regards, Dr. V.A. Zharkov.

No, most of these enthusiasts write in basic vanilla C++ and use x86
assembly to optimise their code. They are attempting to get high quality 3D
engines using the power of todays CPUs, without using the GPU.
You won't find a reference for 3D graphics with .NET period. Sorry to say
this. Only by using D3D or GL will you find a book for a beginner. As I
say, you will have to read-up on first principles and implement this in your
own way in whatever language you like (I started learning 3D graphics ages
ago with a book containing "Basic" and "Psuedo-Code" which I implemented in
Borland Turbo C++ 2.0! It was painfull but it worked.
However, I am going to have a go at getting a GDI+ basic 3D rendering engine
going sometime this week; just to demonstrate to you some of the principles
involved. If you are patient, I will post it to this thread.
Just out of curiosity, why do you not wish to use DirectX or OpenGL?
Good luck!

1. Many thanks for your very valuable advice.
2. On a site http://www.magic-software.com/Books.html I have looked the
book, recommended you: Schneider P.J. and Eberly D.H. Geometric Tools for
Computer Graphics. Morgan Kaufmann, 2002. - 1056 p.
In this book are given the small slices of the program on a pseudo-code,
and the program of construction of 3D - graphics is absent.
3. In the previous answer you have written: "A few enthusiasts spend time
writing and optimizing their own software rendering engines with advanced
features (some of them are actually very good):"
How to find the programs of these enthusiasts on building the 3D -
graphics of function z=f (x, y) and only for Visual Studio .NET (without use
DirectX, OpenGL, MathCAD, MatLab, Maple and similar packages)?
Beforehand many thanks for your answer. Best regards, Dr. V.A. Zharkov.

Mr. Robin Tucker.
1. Once again many thanks for your very valuable advices.
2. Willingly I answer on your question (Just out of curiosity, why do you
not wish to use DirectX or OpenGL?).
Both DirectX, and OpenGL is the another's closed program ("black box"),
which we can not change, and we can only apply in the limited limits. At me
on a table lay the two books with the programs on construction of a surface
z=f (x, y) in the dialog box of Visual C++ .NET with the help OpenGL (in my
previous letter I have given the reference to one of articles in the
Internet from the book). It is the very complex programs, and that in them
to understand, it is necessary to spend a lot of time for initial study
OpenGL. In the books are constructed beautiful color cubes and surface for
demonstration to the schoolboys. At the decision of my engineering task it
is necessary to present this surface from sheet metal as a grid of finite
elements, to define through a finite element method (FEM) of strains and
stresses in nodes of this surface after treatment of the tool and from nodes
to construct the diagrams of strains and stresses. To construct such
diagrams, it is necessary to spend very many more time for the profound
study OpenGL, and still it is not known, whether the limited opportunities
OpenGL will allow to construct the diagrams at a good engineering level.
Naturally there is a question, what for to spend a lot of time for study
another's and complex OpenGL, when the same time can be spent for
development of the open program in the advanced platform Visual Basic .NET
2003, that I and try to make with your kind help.
3. I will be very grateful to you, if you will send materials on "GDI+ basic
3D rendering engine".
4. If this thread unexpectedly will break, it is possible to you to address

Ok, I think I'm starting to see where you are coming from here. Heres the
problem: you want your students to be able to code this graphics
assignment/s but you don't want them to have to learn a graphics API in
order to do so? There is no solution to this problem unless you develop
yourself a class handling the basics required in order to complete the
assignment and give it to them to fill in the details. I can only give you
suggestions on how to proceed here, because my time is limited! The
solution as I see it is to use an Excel spreadsheet and to use VB scripts in
Excel to modify a 3D graph object in the spreadsheet. Thus you will avoid
any/all consideration of 3D graphics and are able to concentrate on
representation of the data you are studying. If you want anything more
complex, I'm afraid the creation of a .NET GDI+ 3D graphics library usable
by your students will be the next step, but it will be time consuming and
limited in scope.
I imagine you will want a 3D "sheet" and that you will be modifying control
points on the sheet in the graph according to values returned from your
experiments. This is easily achieved in Excel - quite possibly without any
programming at all (create a 3D graph from data in Excel).
