9.2.6 Fall sample

C++ code

mglData a(50,40);
a.Modify("0.6*sin(2*pi*x)*sin(3*pi*y) + 0.4*cos(3*pi*(x*y))");
gr->Rotate(40,60);
gr->Box();
gr->Fall(a);

MGL code

new a 50 40
modify a '0.6*sin(2*pi*x)*sin(3*pi*y) + 0.4*cos(3*pi*(x*y))'
rotate 40 60
box
fall a

Pure C code

HMDT a = mgl_create_data_size(50,40,1);
mgl_data_modify(a,"0.6*sin(2*pi*x)*sin(3*pi*y) + 0.4*cos(3*pi*(x*y))",0);
mgl_rotate(gr,40.,60.,0.);
mgl_box(gr,1);
mgl_fall(gr,a,0);
mgl_delete_data(a);

Fortran code
