C++ code

MGL code

new a 60 50 40
modify a '-2*((2*x-1)^2 + (2*y-1)^2 + (2*z-1)^4 - (2*z-1)^2 - 0.1)'
rotate 40 60
box
surf3 a 'bgrd'

Pure C code

HMDT a = mgl_create_data_size(60,50,40);
mgl_data_modify(a,"-2*((2*x-1)^2 + (2*y-1)^2 + (2*z-1)^4 - (2*z-1)^2 - 0.1)",0);
mgl_rotate(gr,40.,60.,0.);
mgl_box(gr,1);
mgl_surf3(gr,a,"bgrd",3);
mgl_delete_data(a);

Fortran code

integer a, mgl_create_data_size
a = mgl_create_data_size(60,50,40);
call mgl_data_modify(a,"-2*((2*x-1)^2 + (2*y-1)^2 + (2*z-1)^4 - (2*z-1)^2 - 0.1)",0);
call mgl_rotate(gr,40.,60.,0.)
call mgl_box(gr,1)
call mgl_surf3(gr,a,'bgrd',3)
call mgl_delete_data(a)

Python

a = mglData(60,50,40);
a.Modify("-2*((2*x-1)^2+(2*y-1)^2+(2*z-1)^4-(2*z-1)^2-0.1)");
