The program is three-dimensional drawing graphs of functions of 2 variables, type f (xy) ie f: R * R-> R,
where x - first variable, y - and the second variable z = f (x, y).
x, y, z - coordinates of the three-dimensional space.
How to use:
In the program f (x, y) = hammered an arbitrary function of two variables, the variable x and variable y.
For example - sin (x) + cos (y)
Press button to draw. The rotation schedule is drawing sliders.
X - it is that the rotation is about the axis Ox, ie the vector with coordinates (1,0,0).
Y - around Oy. Etc.
Zoom in and out the drawing done with the mouse wheel.
The shift schedule is done with the mouse.
Also in the program there is a certificate in which are listed all the standard mathematical functions.
With the aid of which, as well as functions of composition, addition +, multiplication and division * / build
The program has a number of shortcomings.
1) The coordinate axes are not signing, and no grid.
I do not know how to draw on the screen OpenGL text, so I'll read the documentation on OpenGL.
The rest of the program is quite workable.
